IBM to acquire MDM supplier initiate methods | killexams.com true Questions and Pass4sure dumps

IBM illustrious today that it plans to purchase initiate methods, one of the vital few remaining unbiased grasp information administration (MDM) vendors.

provoke methods, primarily based in Chicago, focuses on MDM and statistics integration application for healthcare and government groups. The proposed acquisition confirms rumors that IBM would build a play within the MDM market and springs just days after Informatica announced its buy of stir competitor Siperian.

"With the addition of provoke's software and its trade potential, IBM will present clients a complete solution for providing the information they need to enhance the neatly-being of patients at a lessen can charge," Arvind Krishna, generic manager of recommendation administration at IBM, observed in an announcement. "similarly, their executive consumers will now abide much more capabilities for gathering and applying tips to serve citizens in a timely and effective manner."

The train of MDM is to create a single view of grasp information -- most commonly client and product statistics -- to exist used utter the pass through a company's operational, transactional and analytical applications.

IBM has invested heavily in its statistics management and analytics stack over the closing a yoke of years, and the acquisition of initiate will continue that style. IBM competes with Oracle, SAP and now Informatica within the birthright away consolidating MDM market.

IBM is additionally likely trying to capitalize on the anticipated enhance in adoption of electronic medical facts, which provoke's MDM expertise supports by pass of helping healthcare companies consolidate patient records.

Rob Karel, an analyst with Cambridge, Mass.-primarily based Forrester analysis, pointed out that each Siperian and stir systems abide struggled to expand their customer bases as independent carriers, making the fresh acquisitions a rational circulate for the two.

"We reached an inflection aspect," stated invoice Conroy, provoke's president and CEO, in a joint conference convoke with IBM. "could they as a diminutive commerce withhold up with the calls for of their consumers [for a more complete data management stack]?" The reply, apparently, turned into no.

The proposed acquisition should noiseless improvement IBM in a yoke of methods, wrote Ray Wang, an analyst with Altimeter neighborhood in San Mateo, Calif., in a weblog establish up following the announcement. IBM will inherit initiate's "amazing" information integration platform and "deep healthcare and public sector event."

The acquisition should noiseless additionally support IBM differentiate its MDM offering from rival Oracle, based on Wang -- but not earlier than IBM does the difficult work of harmonizing its numerous MDM applied sciences.

"today, IBM offers Infosphere MDM Server for PIM according to Trigo product assistance administration [PIM] and Infosphere MDM Server 9 in accordance with DWL for customer records integration [CDI]," Wang wrote. "initiate programs provides a third and equipped product into the lineup it truly is optimized for customer information."

Arvind Krishna, GM of IBM's suggestions management business, stated IBM plans to present both product records and consumer information MDM as divide choices.

initiate has 347 personnel and counts CVS/Caremark, Humana, and the North Dakota department of Human functions amongst its consumers. Neither commerce printed phrases of the deal, which is anticipated to shut within the first quarter.


IBM preps Watson AI features to Hurry on Kubernetes | killexams.com true Questions and Pass4sure dumps

Two of IBM’s Watson-branded assortment of computing device-intelligence features could exist obtainable to Hurry as standalone applications in the public or inner most cloud of your choice. IBM is offering these local Watson services atop IBM Cloud inner most for statistics, a combined analytics and information governance platform that may likewise exist deployed on Kubernetes. 

Ruchir Puri, CTO and chief architect for IBM Watson, mentioned this was driven by pass of consumer exact for machine discovering options that can exist Hurry the Place consumer information already resides, customarily a multicloud or hybrid cloud environment (see related interview).

“as opposed to trying to go the statistics to a single cloud, and create a lockin in this open compute-atmosphere-pushed world, they are making purchasable AI and relocating it to the statistics,” Puri stated. The concept follows how Hadoop and other mass statistics-processing systems accomplish work on statistics in location, rather than stirring the information to the processing.

at present, handiest two services—Watson assistant and Watson OpenScale, which Puri described as “flagship products”—can exist provided to consumers as standalone applications. Watson assistant is used to construct “conversational interfaces” similar to chatbots; Watson OpenScale gives “automated neural community design and deployment,” or a means to train, installation, and oversee laptop researching models and neural networks in an enterprise surroundings.

IBM Cloud inner most for facts is composed of preconfigured microservices that Hurry on a multinode, Kubernetes-based mostly IBM Cloud inner most cluster. Puri referred to the consumer is expected to accomplish their personal integration between IBM Cloud inner most for records and its endemic information outlets; such integration isn’t dealt with with the aid of IBM without delay. 

Puri made it lucid these local Watson incarnations don't just forward API calls from a local proxy into IBM-hosted Watson. The customer runs its personal local incarnation of the service, delivered atop IBM Cloud inner most and working within the atmosphere of option. Supported environments comprise Amazon web features, Google Cloud, Microsoft Azure, and crimson Hat OpenShift. local Watson features are API-compatible with Watson services running in IBM Cloud.

What’s more likely to change is the effects delivered from local Watson incarnations versus the master version of Watson, since the endemic types needs to exist periodically updated. Puri could not provide a particular timeline for a pass commonly current models of endemic Watson features will reach down the pike (quarterly, annually, and so on.), but he did verify that it can exist up to date “on a comparatively customary foundation.”

The volume of apparatus materials vital to dedicate to a Watson carrier instance varies reckoning on the workload. Some SLAs for the provided products encompass a prescription for the computing environment (memory, cores, GPUs) required for the preferred efficiency, Puri noted. both virtualized and bare-steel deployments are supported.

other Watson features might exist made available in the community atop IBM Cloud inner most later. IBM plans later in 2019 to convey Watson capabilities Studio, which “discovers meaningful insights from unstructured textual content without writing any code,” and Watson herbal Language understanding, an automatic metadata extraction tool. The latter, Puri noted, is already used in Watson assistant as an interior microservice, so most of the work to port it to a endemic incarnation has already been completed.

This current incarnation of Watson services provides a glimpse into probably the most reasons around IBM’s acquisition of red Hat. IBM Cloud deepest can employ the Kubernetes-powered OpenShift as its base, and Watson’s features had been remodeled over a three-12 months duration around Kubernetes and containers, Puri mentioned. once purple Hat is totally beneath IBM’s umbrella, it seems likely that pink Hat’s infrastructure skills will free up cloud portability for future IBM records-centric features, Watson and otherwise.

This information is fragmented throughout working environments and sometimes represented inconsistently. initiate's know-how helps acquire this facts no depend the Place it resides to establish a single a single, multi-goal view of crucial commerce suggestions, which is likewise called master statistics.

provoke's utility helps healthcare shoppers work more intelligently and successfully with timely entry to affected person and clinical records. with the aid of including initiate's application to its application portfolio, IBM might exist improved equipped to waiton clients draw on records from hospitals, doctors' places of work and payers to create a single, trusted shareable view of millions individual affected person statistics. The acquisition will additionally boost IBM's means to permit governments to access assistance from numerous methods and groups to provide more advantageous capabilities to residents.

"IBM's acquisition of stir underscores their commitment to the employ of superior know-how to support resolve complications faced through each healthcare groups and governments world wide," illustrious Arvind Krishna, time-honored supervisor, tips administration, IBM.

IBM GDPS V3.3: Improving cataclysm Recovery Capabilities to waiton Ensure a Highly Available, Resilient commerce Environment | killexams.com true questions and Pass4sure dumps

Overview

GDPS(TM) is IBM's premier continuous availability and cataclysm recovery solution. IBM is haughty to publish the universal availability of GDPS V3.3. Available on January 25, 2006, GDPS V3.3 offers:

Enhanced availability with autonomic detection of "Soft Failures" on disk control units to trigger a HyperSwap(TM)Exploitation of XRC enhancements for increased scalability in large I/O configurations and configurations with intensive I/O characteristicsEase of employ to support z/OS® V7 XRC+ staging data setsExpanded functionality to provide data consistency between disk and duplexed Coupling Facility (CF) structures

In addition, IBM is reannouncing the universal availability of GDPS/Global Mirror (GDPS/GM). Based upon IBM TotalStorage® Global Mirror technology, IBM GDPS/Global Mirror automation can waiton simplify data replication across any number of IBM System z(TM) and/or open system servers to a remote site that can exist at virtually any distance from the primary site. This can waiton ensure rapid recovery and restart capability for your IBM System z9(TM), zSeries®, and open systems data for testing purposes as well as both planned and unplanned outages. GDPS/GM likewise provides automation facilities to reconfigure your System z9 and zSeries servers and to restart the systems that Hurry on these servers for testing and for actual cataclysm recovery.

GDPS/Global Mirror automation technology is designed to manage the IBM TotalStorage Global Mirror copy technology, monitor the mirroring configuration, and automate management and recovery tasks.

GDPS is likewise providing a current "three-site" solution combining the benefits of GDPS/PPRC using Metro Mirror with GDPS/Global Mirror using Global Mirror technology. This solution, GDPS Metro/Global Mirror, is designed to provide the near-continuous availability aspects of HyperSwap and waiton forestall data loss within the Metro Mirror environment, along with providing a long-distance cataclysm recovery solution with no response-time impact. Metro/Global Mirror has been available via an RPQ since October 31, 2005.

More circumstantial information on the GDPS service offerings is available on the Internet at

http://www.ibm.com/servers/eserver/zseries/gdps

Availability date

Available now (as of January 25, 2006):RCMF/PPRC V3.3GDPS/PPRC V3.3GDPS/PPRC HyperSwap Manager V3.3RCMF/XRC V3.3GDPS/XRC V3.3GDPS/Global Mirror V3.3GDPS Metro/Global Mirror V3.3

Description

IBM Global Services continues to enhance GDPS with:

Extended HyperSwap functionality with IOS timing triggerImproved availability with enhanced recovery support in a CF structure duplexing environmentPerformance improvements for System Logger in a z/OS Global Mirror (previously known as XRC) environmentScalability improvements for XRCUnlimited distance solution for z/OS and open data with the current GDPS/Global Mirror offering

Unplanned HyperSwap IOS timing trigger

If a disk subsystem experiences a "hard failure" such as a boxed device, rank array failure, or disk subsystem failure, current versions of GDPS/PPRC and GDPS/PPRC HyperSwap Manager (GDPS/PPRC HM) are designed to detect this and automatically invoke HyperSwap to transparently switch utter primary PPRC disks with the secondary disks within seconds.

Occasionally, no signal comes back after an I/O operation has started. The I/O starts, but it is as if it doesn't end. There are no errors returned. The only indication that something is wrong is that the z/OS I/O Missing Interrupt Handler (MIH) detects this and generates a message. It is then up to the operator to see the message and design out what to do. By that time, it is possible that the transactions waiting for I/O and holding on to resources can in whirl occasions other transactions to wait, and can bring the entire system to a stop.

The HyperSwap IOS timing trigger is designed to allow HyperSwap to exist invoked automatically when user-defined I/O timing thresholds are exceeded. In a matter of seconds, transactions can now resume processing on the secondary disk, providing availability benefits and avoiding operator intervention.

The HyperSwap IOS Timing trigger requires APAR OA11750 available on z/OS V1.4.

HyperSwap is available with the GDPS/PPRC and GDPS/PPRC HyperSwap Manager offerings.

GDPS enhanced recovery support

In the event of a primary site failure, the current GDPS/PPRC cannot ensure that the CF structure data may exist time-consistent with the "frozen" copy of data on disk, so GDPS must discard utter CF structures at the secondary site when restarting workloads. This results in loss of "changed" data in CF structures. Users must execute potentially long-running and highly variable data recovery procedures to restore the lost CF data.

GDPS enhanced recovery is designed to ensure that the secondary PPRC volumes and the CF structures are time consistent, thereby helping to provide consistent application restart times without any special recovery procedures.

If you specify the FREEZE=STOP policy with GDPS/PPRC and duplex the usurp CF structures, when CF structure duplexing drops into simplex, GDPS is designed to direct z/OS to always withhold the CF structures in the site where the secondary disks reside. This helps to insure the PPRC volumes and recovery-site CF structures are time consistent thereby providing consistent application restart times without any special recovery procedures. This is especially significant for customers using DB2® data sharing, IMS(TM) with shared DEDB/VSO, or WebSphere® MQ shared queues.

GDPS enhanced recovery support requires z/OS APAR OA11719, available back to z/OS V1.5.

Improving performance

System logger provides current support for XRC+ by allowing you to pick asynchronous writes to staging data sets for logstreams. Previously, utter writes had to exist synchronous. This limited the throughput for high-volume logging applications such as WebSphere, CICS®, and IMS. The competence to Do asynchronous writes can allow the employ of z/OS Global Mirror (XRC) for some applications for which it was not previously practical. XRC+ is available on z/OS and z/OS.e V1.7.

Refer to Preview: IBM z/OS V1.7 and z/OS.e V1.7: World-class computing for On exact Business, Software Announcement 205-034 dated February 15, 2005.

GDPS/XRC has extended its automation to support XRC+. It is designed to provide the competence to configure and manage the staging data set remote copy pairs.

Scalability

GDPS/XRC support is being extended to waiton ameliorate XRC scalability for large systems by:

Write PacingAPAR OA09239 provides for the current XRC Write Pacing support. By automatically inserting delays into the I/O response for high-intensity update applications, XRC can then forestall the secondary disk in the remote site from falling behind, delaying the RPO for utter applications.

Exploitation of the Write Pacing function on GDPS/XRC systems requires APAR 65 (AG31D65), which is fully compatible with utter existing supported GDPS/XRC software levels.

Parallel executionPreviously, GDPS typically processed utter XRC System Data Movers (SDMs) in sequence within an LPAR. With GDPS V3.3, many XRC commands can now exist done in parallel across utter the SDMs. A parallel execution of XRC commands across utter SDMs allows for improved responsiveness, improved usability, and reduced recovery time.

Support for more than 14 SDMsPreviously, XRC supported up to 14 coupled SDMs, split across up to five SDM address spaces per z/OS LPAR. current support expands this to allow up to 14 Coupled eXtended Remote Copy (CXRC) sessions. Each CXRC can consist of one or more XRC rational sessions. Additionally, Multiple eXtended Remote Copy (MXRC) currently allows the user to Hurry up to five XRC rational sessions within a single LPAR. This enhancement will allow significantly more SDMs, thereby increasing the number of parallel paths to transfer data. This allows GDPS/XRC to wield larger configurations and higher throughputs while maintaining the client's service level agreements. More information on CXRC can exist institute in z/OS DFSMS Advanced Copy Services (SC35-0428-09).

The planned availability of GDPS support for more than 14 coupled SDMs is second quarter 2006.

XRC Performance Monitor (XPM) updates

In addition to the above enhancements, XPM is being modified to support the current larger master sessions. XPM will abide the competence to array (via the Interactive Interface) and process (via the Exception Batch Monitor) cluster-level data.

Product positioning

The GDPS solution suite includes six different service offerings to meet different customer requirements:

RCMF/PPRCRemote Copy Management Facility (RCMF) provides management of the remote copy environment and disk configuration from a central point of control. The RCMF/PPRC offering can exist used to manage a PPRC (Metro Mirror) remote copy environment.

RCMF/XRCRCMF/XRC is a cataclysm recovery offering which can exist used to manage an XRC (z/OS Global Mirror) remote copy environment.

GDPS/PPRC HyperSwap ManagerGDPS/PPRC HyperSwap Manager provides either a single-site near-continuous availability solution or a multi-site cataclysm recovery solution. It is an entry-level solution available at a cost-effective price. GDPS/PPRC HyperSwap Manager is designed to allow customers to enlarge availability and provide applications with continuous access to data. Today, GDPS/PPRC HyperSwap Manager appeals to zSeries customers who require continuous availability and extremely rapidly recovery.

Within a single site, or multiple sites, GDPS/PPRC HyperSwap Manager extends Parallel Sysplex® availability to disk subsystems by masking planned and unplanned disk outages caused by disk maintenance and disk failures. It likewise provides management of the data replication environment and automates switching between the two copies of the data without causing an application outage, therefore providing near-continuous access to data.

The GDPS/PPRC HyperSwap Manager solution is a subset of the replete GDPS/PPRC solution, designed to provide a very affordable entry point to the replete family of GDPS/PPRC offerings. It features specially priced limited-function Tivoli® System Automation and NetView® software products, thus satisfying the GDPS software automation prerequisites with a lower price and a cost-effective entry point to the GDPS family of offerings. Users who already abide the full-function Tivoli System Automation and NetView software products may continue to employ them as the prerequisites for GDPS/PPRC HyperSwap Manager.

A customer can migrate from a GDPS/PPRC HyperSwap Manager implementation to the full-function GDPS/PPRC capability as commerce requirements exact shorter recovery time objectives. The initial investment in GDPS/PPRC HyperSwap Manager is protected when you pick to go to full-function GDPS/PPRC by leveraging the existing GDPS/PPRC HyperSwap Manager implementation and skills.

GDPS/PPRCGDPS/PPRC complements a multisite Parallel Sysplex implementation by providing a single, automated solution to dynamically manage storage subsystem mirroring, disk and tape, processors, and network resources. It is designed to waiton a commerce attain continuous availability and near-transparent commerce continuity (disaster recovery) with data consistency and no or minimal data loss. GDPS/PPRC is designed to minimize and potentially eliminate the repercussion of any failure, including disasters, or a planned outage.

GDPS/PPRC is a full-function offering that includes the capabilities of GDPS/PPRC HM. It is designed to provide an automated end-to-end solution to dynamically manage storage system mirroring, processors, and network resources for planned and unplanned events that could interrupt continued IT commerce operations.

The GDPS/PPRC offering is a world-class solution built on the z/OS platform and yet can manage a heterogeneous environment.

GDPS/PPRC is designed to provide the competence to accomplish a controlled site switch for both planned and unplanned site outages, with no or minimal data loss, maintaining replete data integrity across multiple volumes and storage subsystems and the competence to accomplish a bonafide Data ground Management System (DBMS) restart - not DBMS recovery - in the second site. GDPS/PPRC is application-independent and therefore can cover your complete application environment.

GDPS/XRCBased upon IBM TotalStorage z/OS Global Mirror (Extended Remote Copy, or XRC), GDPS/XRC is a combined hardware and z/OS software asynchronous remote-copy solution. Consistency of the data is maintained via the Consistency Group function within the System Data Mover. GDPS/XRC includes automation to manage remote copy pairs and automates the process of recovering the production environment with limited manual intervention, including invocation of CBU, thus providing significant value in reducing the duration of the recovery window and requiring less operator interaction. GDPS/XRC is capable of the following attributes:

Disaster recovery solutionRTO between an hour to two hoursRPO less than one minuteProtects against localized or regional disasters, depending on the distance between the application site and the cataclysm recovery site (distance between sites is unlimited)Minimal remote copy performance impactGDPS/XRC is well suited for large System z workloads and can exist used for commerce continuance solutions, workload movement, and data migration.

Because of the asynchronous nature of XRC, it is possible to abide the secondary disk at greater distances than would exist acceptable for Metro Mirror (synchronous PPRC). Channel extender technology can exist used to Place the secondary disk thousands of kilometers away.

In some cases an asynchronous cataclysm recovery solution is more desirable than one that uses synchronous technology. Sometimes applications are too sensitive to accept the additional latency incurred when using synchronous copy technology.

GDPS/Global Mirror

The latest member of the GDPS suite of offerings, GDPS/Global Mirror offers a multisite, end-to-end cataclysm recovery solution for your IBM z/OS systems and open systems data.

IBM GDPS/Global Mirror automation technology can waiton simplify data replication across any number of System z(TM) systems and/or open system servers to a remote site that can exist at virtually any distance from the primary site. This can waiton ensure rapid recovery and restart capability of your environment for both testing and cataclysm recovery, and restart capability for your open systems environment for testing and cataclysm recovery. Being able to test and rehearse recovery allows you to build skills in order to exist ready when a cataclysm occurs.

GDPS/Global Mirror automation technology is designed to manage the IBM TotalStorage Global Mirror copy services and the disk configuration, monitor the mirroring environment, and automate management and recovery tasks. It can accomplish failure recovery from a central point of control. This can provide the competence to synchronize System z and open systems data at virtually any distance from your primary site.

The point-in-time copy functionality offered by the IBM TotalStorage Global Mirror technology allows you to initiate a restart of your database managers on any supported platform, to waiton reduce complexity and avoid having to create and maintain different recovery procedures for each of your database managers.

All this helps provide a comprehensive cataclysm recovery solution.

The six offerings listed above can exist combined as follows:

GDPS/PPRC used with GDPS/XRC (GDPS PPRC/XRC)GDPS PPRC/XRC provides the competence to combine the advantages of metropolitan-distance commerce Continuity and regional or long-distance cataclysm Recovery. This can provide a near-continuous availability solution with no data loss and minimum application repercussion across two sites located at metropolitan distances, and a cataclysm recovery solution with recovery at an out-of-region site with minimal data loss.

A typical GDPS PPRC/XRC configuration has the primary disk copying data synchronously to a location within the metropolitan locality using Metro Mirror (PPRC), as well as asynchronously to a remote disk subsystem a long distance away via z/OS Global Mirror (XRC). This enables a z/OS three-site tall availability and cataclysm recovery solution for even greater protection from planned and unplanned outages.

Combining the benefits of PPRC and XRC, GDPS PPRC/XRC enables:

HyperSwap capability for near-continuous availability for a disk control unit failureOption for no data lossData consistency to allow restart, not recoveryLong-distance cataclysm recovery site for protection against a regional disasterMinimal application impactGDPS automation to manage remote copy pairs, manage a Parallel Sysplex configuration, and accomplish planned as well as unplanned reconfigurationsThe very primary volume is used for both PPRC and XRC data replication and can support two different GDPSs: GDPS/PPRC for metropolitan distance and commerce continuity, and GDPS/XRC for regional distance and cataclysm recovery.

The two mirroring technologies and GDPS implementations work independently of each other, yet provide the synergy of a common management scheme and common skills.

Since GDPS/XRC supports zSeries data only (z/OS, Linux on zSeries), GDPS XRC is a zSeries solution only.

GDPS/PPRC used with GDPS/Global Mirror (GDPS Metro/Global Mirror)

GDPS Metro/Global Mirror has the profit of being able to manage across the configuration utter formats of data, as Global Mirror is not limited to zSeries formatted data.

GDPS Metro/Global Mirror combines the benefits of GDPS/PPRC using Metro Mirror, with GDPS/Global Mirror using IBM TotalStorage Global Mirror. A typical configuration has the secondary disk from a Metro Mirror remote copy configuration in whirl becoming the primary disk for a Global Mirror remote copy pair. Data is replicated in a "cascading" fashion.

Combining the benefits of PPRC and Global Mirror, GDPS Metro/Global Mirror enables:

HyperSwap capability for near-continuous availability for a disk control unit failureOption for no data lossMaintain cataclysm recovery capability after a HyperSwapData consistency to allow restart, not recovery, at either site 2 or site 3Long-distance cataclysm recovery site for protection against a regional disasterMinimal application impactGDPS automation to manage remote copy pairs, manage a Parallel Sysplex configuration, and accomplish planned as well as unplanned reconfigurations

In addition, GDPS Metro/Global Mirror can Do this for both zSeries as well as open data, and provide consistency between them.

GDPS Metro/Global Mirror is only available via RPQ.

AWS CodeCommit triggers bolster employ of Git | killexams.com true questions and Pass4sure dumps

AWS CodeCommit was launched in 2015, allowing developers to Hurry repositories of Git on AWS. But the announcement was mostly hushed because it didn't add any special features. However, I suspected it marked a first step in integrating a cloud-based workflow for Git on AWS. That has now reach to fruition -- with support for triggers based on events in a Git repository in AWS CodeCommit.

Triggers allow IT teams to respond to events that occur in a repository, such as a developer pushing out current code. The GitFlow methodology, along with trigger use, allow developers to properly implement both continuous integration -- testing code as it is committed -- and continuous delivery -- deploying code as soon as it is verified and committed. With CodeCommit, developers can employ Git on AWS to deploy current versions to both evolution and production environments entirely by pushing code to specified branches.

One very common employ case for triggers is to automatically build current releases of code pushed to either a evolution or master arm of a repository. Developers can completely automate testing and deploy a Node.js application from AWS CodeCommit directly to AWS Elastic Beanstalk.

The Lambda test function

Make certain code validates a given set of tests before deploying it from a repository. Unit tests or even universal "lint" compilations can forestall simple syntax errors. For Node, I prefer to employ the simple ESLint script -- installable through npm. This "linter" checks to build certain basic syntax is obeyed. It likewise checks for common errors enjoy typos and the employ of reserved keywords where they're not allowed.

Before AWS CodeCommit executes a Lambda function, it must abide the usurp access. Developers need to create a current JSON consent file, enjoy this one:

{

   "FunctionName": "MyCodeCommitFunction",

   "StatementId": "1",

   "Action": "lambda:InvokeFunction",

   "Principal": "codecommit.amazonaws.com",

   "SourceArn": "arn:aws:codecommit:us-east-1:80398EXAMPLE:MyDemoRepo",

   "SourceAccount": "80398EXAMPLE"

}

 Then, upload it through the AWS command-line interface.

aws lambda add-permission --cli-input-json file://AllowAccessfromMyDemoRepo.json

The data your Lambda function will receive looks like:

{ Records: [

 {

   awsRegion: 'us-east-1',

   codecommit: {

    references: [ {

      commit: '0000000000000000000000000000000000000000',

      ref: 'refs/heads/all'

    } ]

   },

   eventId: '123456-7890-ABCD-EFGH-IJKLMNOP',

   eventName: 'TriggerEventTest',

   eventPartNumber: 1,

   eventSource: 'aws:codecommit',

   eventSourceARN: 'arn:aws:codecommit:us-east-1:80398EXAMPLE:MyDemoRepo',

   eventTime: '2016-03-08T20:29:32.887+0000',

   eventTotalParts: 1,

   eventTriggerConfigId: ‘123456-7890-ABCD-EFGH-IJKLMNOP',

   eventTriggerName: 'MyCodeCommitFunction',

   eventVersion: '1.0',

   userIdentityARN: 'arn:aws:sts::80398EXAMPLE:assumed-role/DevOps/cmoyer'

} ] }

There are some notable fields to solemnize here. The "userIdentityARN" indicates the user who initiated the push. At a minimum, the Lambda function should log this so developers know who initiated the build request. But developers can likewise empower who is allowed to initiate current build requests. For example, the Lambda function can exist designed to only build current versions to production initiated by developers who are trusted to push production code.

AWS CodeCommit was launched in 2015, allowing developers to Hurry repositories of Git on AWS.

The second notable domain to note here is under "code commit/references/ref," which shows the arm or branches that were committed.

This check needs to examine code and Hurry a custom command, which may finish up taking longer than five minutes. Instead, I employ my Lambda function to execute an EC2 Container Service (ECS) task. This likewise allows developers to trigger other events, such as pile and deploying current releases birthright through an ECS task.

This Lambda function triggers an ECS task:

/**

 * Execute an ESLint Task

 * to check the Code that was committed

 */

var AWS = require('aws-sdk');

var ecs = current AWS.ECS({ region: 'us-east-1' });

 

exports.handler = function(data, context){

   console.log(JSON.stringify(data));

 

   var counter = data.Records.length;

   function done(){

      counter--;

      if(counter === 0){

         context.succeed('OK');

      }

   }

 

   data.Records.forEach(function processRecord(record){

      console.log('CHANGES from', record.userIdentityARN);

      record.codecommit.references.forEach(function(ref){

       counter++;

       ecs.runTask({

          taskDefinition: ‘ECSBuilder',

          overrides: {

             containerOverrides: [

               {

                  command: [

                     ‘./checkBuild',

                     record.eventSourceARN.split(':')[5],

                    ref.ref.replace(‘refs/heads‘,''),

                    ref.commit,

                  ],

                  name: ‘ECSBuilder',

               },

             ],

          },

          startedBy: 'ESLint: ' + record.userIdentityARN.split('/')[1],

       }, function(err, resp){

          if(err){

             console.error('ERROR', err);

          } else {

             console.log('Successfully started', resp);

          }

          done();

      });

      });

     done();

   });

}

Note the employ of a "counter" function; a single push event could actually trigger multiple repository updates. This code makes inevitable to test them all.

Adding triggers to a CodeCommit repository

After creating the Lambda function, developers configure CodeCommit to fire the Lambda function on specific events. This can exist configured in multiple ways, but it is generally best to build certain the CodeCommit repository fires the event for any push events to the repository. The function can likewise exist configured to filter pushes to specific branches.

Click on the newly added "triggers" option and pick "Create trigger" to comeby started.

Create a trigger in AWS CodeCommit Developers can create a trigger for a Lambda function in AWS CodeCommit.

Next, fill out the details to create the trigger:

Configure the Lambda trigger. Fill in the details to set up the trigger for the Lambda function.

In this example, the function only executes on a push to existing branches. If a evolution cycle uses GitFlow, developers may likewise need to comprise "Create arm or tag" to build certain current release branches likewise trigger this function. In both cases, build certain to fill out the arm names either to "All branches" or pick specific branches. pick "AWS Lambda" as the service to ship to, and select the Lambda function. Once everything is set, employ the "Test trigger" option to build certain the code repository has access. If it doesn't, retrace the steps to empower the CodeCommit repository to convoke Lambda functions.

Creating an ECS task

The final step is to create an ECS job and empower the Lambda role to execute it. ECS tasks execute Docker repositories from Amazon EC2 Container Registry (ECR), so the easiest mode is to push a Docker image up to ECR where the job can Hurry it.

A simple Docker script may determine enjoy this:

FROM node:5.6.0

 

# build certain apt is up to date

RUN apt-get update

 

# Install global packages

RUN npm install --global grunt-cli eslint

 

# install Git and curl

# Python is required by the "memcached" node module

RUN apt-get install -y Git Git-core curl python build-essential

 

# Create a bashrc

RUN touch ~/.bashrc

 

# Copy their bundled code

COPY . /usr/local/app

 

# Set the working directory to where they installed their app

WORKDIR /usr/local/app

This script needs to exist in a directory with the script to check the build within the repository. In the Lambda script they created above, they Hurry a script called "checkBuild" that contains the ultimate partake of the repository's designation -- "eventSourceARN" -- as well as a reference to the consign arm and the exact consign ID. With these three items, developers can build a check script that examines the exact version that pushes the trigger.

The checkBuild.sh script should determine enjoy this:

#!/bin/sh

REPOSITORY=$1

BRANCH=$2

COMMIT=$3

 

# Add the Known Host

ssh-keyscan -H Git-codecommit.us-east-1.amazonaws.com >> ~/.ssh/known_hosts

 

# Check out the repository

Git clone ssh://USERNAME@Git-codecommit.us-east-1.amazonaws.com/v1/repos/${REPOSITORY} build -b ${BRANCH}

 

cd build && Git checkout ${COMMIT} && eslint .

Make certain to supersede "USERNAME" with a convincing Identity and Access Management (IAM) user that has secure shell (SSH) access to the AWS CodeCommit repositories you're testing. It's best to create a current IAM user specifically for this build service, give it access to the repositories and upload an SSH public key for it.

Once this is set, developers can build and deploy the Docker image to the ECR and then employ that to create the ECS task. The Lambda function sets up the command, so the job just needs to point to the Docker repository for the image.

Although this code runs "ESlint" on the checked out code, it neither notifies anyone of the results nor does it automatically deploy anything if the build succeeds. Unit tests can likewise exist executed here to build certain everything passes. A benign pass to Do this is to build notifications birthright into grunt to build certain the results are sent to developers through integrations with Slack, Flowdock or email notifications.

This one current option from AWS for adding basic hook support for CodeCommit can open up a whole current world of opportunities for using Git on AWS for continuous integration and deployment.


Web Services and SOA | killexams.com true questions and Pass4sure dumps

People sometimes request what a service-oriented architecture enables today that could not abide been done with the older, proprietary integration stacks of the past 5 to 15 years, such as those from Tibco, IBM, or Vitria. One such competence is the greater degree of interoperability between heterogeneous technology stacks that is made possible by the standards SOA is built on, such as Web services and BPEL. Although interoperability is only one facet of the SOA value proposition, it is one that has become increasingly more important, due in large partake to the evolving IT environment, merger and acquisition activity, and increased partner connectivity.

pile commerce solutions for SOA requires the competence to secure data exchanged over a network, and control access to services in an environment where long-running commerce processes and asynchronous services are increasingly common. To meet these key requirements, two WS-* standards abide moved to the forefront: WS-Security for authentication and encryption of service data, and WS-Addressing for correlation of messages exchanged with asynchronous services.

As these standards abide begun to enmesh hold, many commercial technologies abide been introduced that add support for them. Likewise, many developers are implementing them in custom applications or with open source frameworks. Furthermore, standards that are logically layers above core Web services and security are referencing them. For example, the WS-BPEL specification is a Web service orchestration language with moneyed support for both synchronous and asynchronous services. BPEL, as it is commonly known, is highly complementary with WS-Security and WS-Addressing.

This article focuses on interoperability with asynchronous messaging and on the security challenges of using BPEL processes to orchestrate Web services deployed onto various technology platforms. The specific specimen used is BPEL processes deployed on Oracle BPEL Process Manager, invoking services implemented with Microsoft .NET Windows Communication Foundation (WCF).

WS-BPEL and WS-Addressing Interoperability ChallengesFor those readers who may not exist versed in asynchronous service requirements, they will first provide some background on why a touchstone such as WS-Addressing is needed. The core Web services standards, including WSDL, SOAP, and XML schema are enough for synchronous service operations in which a client of a service sends a request and either gets no response at utter (a "one-way" operation) or gets a result back as the output of the operation itself. In either case, the operation completes the interaction between the service client and the service itself.

However, for rational operations that may enmesh a long time to complete, the concept of an asynchronous operation whereby the client initiates a service operation but does not wait for an immediate response makes sense. At some later time, the service will convoke the client back with the result of the operation - or with an mistake or exception message. In this case, the client must pass at least two pieces of information to the service: a location where the service can convoke the client back with the result, and an identifier of some sort that will allow the client to uniquely identify the operation with which the callback is associated. Early in the evolution of Web services standards, individual projects would comprise custom mechanisms for interacting with asynchronous services; however, this meant that developers had to explicitly code this support, and interoperability among toolkits was nonexistent.

WS-Addressing provides a touchstone for describing the mechanisms by which the information needed to interact reliably with asynchronous Web services can exist exchanged. In the long term, this promises seamless interoperability, even for asynchronous services, between clients and services implemented on different technology stacks.

The main purpose of WS-Addressing is to incorporate message-addressing information into SOAP messages (for example, where the provider should ship a response). SOAP is an envelope-encoding specification that represents Web service messages in a transport neutral format. However, SOAP itself does not provide any features that identify endpoints. The customary endpoints, such as message destination, foible destination, and message intermediary are delegated up to the transport layer. Combining WS-Addressing with SOAP creates a complete messaging specification. WS-Addressing specifies that address information exist stored in SOAP headers in an independent manner, instead of embedding that information into the payload of the message itself. WS-Addressing is complemented by two other specifications, WS-Addressing SOAP Binding, and WS-Addressing WSDL Binding which specify how to delineate the WS-Addressing properties into SOAP and WSDL respectively.

At a tall level, WS-Addressing defines an EndpointReference construct to delineate a Web service endpoint. It likewise defines a set of headers, ReplyTo, FaultTo, RelatesTo, and MessageId which are used to dynamically define an asynchronous message flood between endpoints.

BPEL relies on WS-Addressing to enhance endpoint representation and asynchronous Web services invocations. However, because WS-Addressing has evolved through several versions, interoperability can exist a challenge. Today up to four different WS-Addressing versions are commonly used-three versions of the specification are named by their release date: the March 2003 version, the March 2004 version, and the August 2004 version, developed before the specification moved to W3C. The 1.0 version, recently completed in May 2006, was developed after the specification went under the umbrella of W3C. After stirring to W3C, the specification split into multiple parts: a core specification, and two specifications that delineate bindings for SOAP and WSDL.

Explicit vs. Implicit Addressing MechanismsIdeally, utter server platforms would support utter possible versions of WS-Addressing, but they are forced to live (and code) in the true world. At this time, many servers support one or more active WS-Addressing versions, but it is noiseless utter too possible that a service and client will exist built on platforms that support incompatible WS-Addressing versions. However, interoperability is possible with a minimal amount of developer effort.

When the very WS-Addressing version is supported by both the process (client) and service layers, it is called "implicit" addressing because the developer need only condition at the metadata level which version of WS-Addressing should exist used to correlate asynchronous messages. In this case, WS-Addressing manipulation is completely transparent to the BPEL process itself, and the SOAP layer simply adds the requested SOAP headers as needed.

However, in order to interoperate with WS-Addressing versions not implicitly supported, a server should provide an specific mechanism by which developers can build and attach WS-Addressing to SOAP messages easily. The following section describes an specific addressing mechanism used to achieve asynchronous service interoperability between Microsoft WCF using WS-Addressing 1.0 and Oracle BPEL Process Manager using WS-Addressing March 2003; however, the very principles should hold birthright for interoperability between any two BPEL and Web service toolkits.

WS-Addressing Interoperability Example: WCF and WS-Addressing Microsoft's Windows Communication Foundation (WCF) represents the next generation of distributed programming and service-oriented technologies built on top of the Microsoft .NET platform for the upcoming Windows Vista release. WCF unifies the existing set of distributed programming technologies such as ASP .NET Web services, .NET Remoting, COM+, and so on, under a common, simple, and service-oriented programming model. WCF implements a vast set of WS-* protocols, including WS-Addressing 1.0.

To demonstrate specific interoperability with WCF, they employ Oracle BPEL Process Manager. It has had moneyed support for WS-Addressing for several years and includes WS-Addressing of March 2003, March 2004, and August 2004. This specimen uses BPEL with WS-Addressing March 2003 and WCF with WS-Addressing 1.0 to demonstrate specific addressing support. reckon the WS-Addressing interoperability scenario illustrated in design 1.

The following explains the occurrences in design 1:

  • A BPEL process exposes WS-Addressing headers on the process WSDL to expose a long-running process as an asynchronous service.
  • A WCF client invokes the BPEL process, and passes the ReplyTo the WS-Addressing v1.0 (www.w3.org/TR/2005/CR-ws-addr-core-20050817/) header representing the URL of a WCF service that is expecting the operation response message. The client likewise sends a MessageID WS-Addressing v1.0 header to uniquely identify the request (step 1).
  • The BPEL process receives the message, performs various operations, and uses the ReplyTo address to define a dynamic endpoint using the WS-Addressing 03/2003 (http://msdn.microsoft.com/webservices/webservices/ default.aspx?pull=/library/en-us/dnglobspec/html/ws-addressing0303.asp). (steps 2-4).
  • The BPEL process sends a reply message to the WCF service specified on the ReplyTo address, and passes the RelatesTo WS-Addressing v1.0 header to enable the WCF client to correlate the original request with the response (step 5).
  • The WCF service receives the response message and is able to correlate it back to the request (step 6).
  • In this example, WCF uses WS-Addressing v1.0; however, the BPEL service uses the March 2003 version of WS-Addressing. To build this work, specific strategies for interoperability need to exist applied, as described below.

    As partake of the process, the WSDL, which represents the interface of the BPEL process, imports the WS-Addressing v1.0 XSD and declares the ReplyTo and MessageID headers as partake of the binding section. It likewise declares messages of type ReplyTo, MessageID, and RelatesTo as variable types in the BPEL process, as shown in Listing 1. Note: By using this technique, we're explicitly declaring that the BPEL process expects the WS-Addressing ReplyTo and MessageID headers as partake of the incoming message.

    Based on the messages types in Listing 1, the BPEL process likewise defines variables of message type ReplyTo, MessageID, and RelatesTo:

    <variable name="wcfServiceAddr" messageType="ns1:wsaReplyTo"/><variable name="wcfRequestId" messageType="ns1:wsaMessageId"/><variable name="wcfResponseId" messageType="ns1:wsaRelatesTo"/>

    With this in place, they can allot the SOAP header information to them later on and vice versa. The next step is to populate these variables from incoming SOAP message:

    <receive name="receiveInput" partnerLink="client"      portType="client:WCFAddr" operation="initiate"      variable="inputVariable" createInstance="yes"      bpelx:headerVariable="wcfServiceAddr wcfRequestId"/>

    By using bpelx:headerVariable (an extension of the WS-BPEL standard), the process code has access to the MessageID sent from the client as well as to its callback location.

    Let's define a variable of type EndpointReference, which will provide the dynamic endpoint reference, needed for initiating the partnerLink later:

    <variable name="wcfEndpoint" element="ns3:EndpointReference"/>

    Note that the ns3 prefix is associated with the WS-Addressing 03/2003 namespace (xmlns:ns3=http://schemas.xmlsoap.org/ws/2003/03/addressing).

    The next step is to populate the wcfEndpoint variable (defined in the previous step) using the ReplyTo header from wcfServiceAddr (Note the <copy> sections, marked yellow).

    By using touchstone BPEL activities, these values are assigned by using a progression of copy rules in an <assign> construct, as shown in Listing 2.

    Assign the wcfEndpoint variable to the wcfService partnerLink, which represents an outgoing reference to a Web service. With this in place, the partnerLink knows which location to call:

    <assign name="PartnerlinkWSAAssign">   <copy>     <from variable="wcfEndpoint"/>     <to partnerLink="wcfService"/>   </copy></assign>

    In order to allow the client to correlate the request and response messages, they abide to copy the value of the wcfRequestId (the unique MessageID) to wcfResponseId (RelatesTo):

    <copy>   <from variable="wcfRequestId" part="parameters" query="/ns2:MessageID"/>   <to variable="wcfResponseId" part="parameters" query="/ns2:RelatesTo"/></copy>

    The ultimate step on the BPEL server-side is to employ an invoke activity, which will convoke the WCF service (defined through the wcfService partnerLink), and to pass the RelatesTo header, available within the wcfResponseId variable. build certain to employ bpelx:inputHeaderVariable for this.

        <invoke name="Invoke_ExternalWCFService" partnerLink="wcfService"       portType="ns1:IOperationCallback" operation="SendResult"       inputVariable="wcfRequest"       bpelx:inputHeaderVariable="wcfResponseId"/>

    After the server side, create a WCF client, which invokes the BPEL process through SOAP. Then create a WCF BindingElement that allows the employ of WS-Addressing v1.0, and wrap the convoke to the BPEL process within an OperationContextScope to populate the WS-Addressing headers, as shown in Listing 3.

    Testing the code in Listing 3 produces a SOAP message that follows. Note the <a:Address> domain containing the service address:

    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"    xmlns:a="http://www.w3.org/2005/08/addressing">    <s:Header>      <a:Action s:mustUnderstand="1">http://tempuri.org/IOperationCallback/SendResult</a:Action>      <a:ReplyTo>        <a:Address>WCF Service Address...</a:Address>      </a:ReplyTo>      <a:To s:mustUnderstand="1">Oracle BPEL Process Address...</a:To>      <a:MessageID>urn:uuid:847b546e-16e5-4ea9-8267-b6fe559f0c1f</a:MessageID>    </s:Header>    <s:Body>Body</s:Body></s:Envelope>
