2 WildFly / JBoss EAP Relationship Supported Supported 10 JBoss EAP 7 Supported

3 EAP7 JBoss EAP is in the leader servers group since 2009

4 EAP7 implementing JEE7 standard

5 Starting from EAP 6: EAP7 Modular Architecture The based architecture of EAP is modularity,

6 EAP7 Modular Architecture EAP7 consist of modules which are running on core server. Most server configurations are sitting at standalone.xml or domain.xml files

7 EAP7 Modular Architecture In order to avoid module from being load you just need to comment it out in the module list.

8 EAP7 Modular Architecture EAP7 is coming with out of the box configured modules Like: standalone-ha.xml configured modules for supporting HA standalone-full.xml configured modules for supporting JMS

9 EAP7 Modular Architecture In this way you can model EAP7 server according to your needs.

10 EAP7 WEB

11 EAP7 web server Undertow is a new web server embedded in EAP7 Lightweight and fully embeddable Composition based architecture Support for Servlet 3.1 Blocking / Non-Blocking NIO based APIs HTTP Upgrade Support for WebSockets, including JSR-356

17 Undertow web server HTTP/2 Data compression of Http headers

18 Batch System in EAP7

19 Batch System in EAP7 Batch Jobs are defined as a part of the JEE7 standard JBeret project is used as a batching subsystem in the EAP7 Framework to make batch jobs like: Salary calculation Stock trading data Processing Batch 1.0

20 Batch System in EAP7 Example of Jobs: Read record from file (or files) Process the record data Add to processed objects list Repeat the previous steps for X times Write each processing Object into DB EAP7 DB processing File Record 1 Record 2 Record 3 Record 4 Record 5

21 Batch System in EAP7 The job is defined by JSL (Job Specification Language) file <job id="import-file" xmlns=" xmlns:xsi=" xsi:schemalocation=" version="1.0"> <listeners> <listener ref="joblistener" /> </listeners> <step id="import-file-chunk" next="reportbatchelet"> <listeners> <listener ref="persistlistener" /> </listeners> <!-- The item-count specified the size of the chunk --> <chunk item-count="3"> <reader ref="recordsreader"> <properties> <!-- Define how values are separated --> <property name="separatorregex" value="[ ]" /> <property name="filename" value="#{jobparameters['filename']}" /> </properties> </reader> <processor ref="contactformatter" /> <writer ref="contactspersister" /> </chunk> </step> <step id="reportbatchelet"> <batchlet ref="reportbatchelet" /> <end on="end" /> </step> </job>

22 Batch System in EAP7 The Job contains steps which are of Chunk type or Batchlet type <job id="import-file" xmlns=" xmlns:xsi=" xsi:schemalocation=" version="1.0"> <listeners> <listener ref="joblistener" /> </listeners> <step id="import-file-chunk" next="reportbatchelet"> <listeners> <listener ref="persistlistener" /> </listeners> <!-- The item-count specified the size of the chunk --> <chunk item-count="3"> <reader ref="recordsreader"> <properties> <!-- Define how values are separated --> <property name="separatorregex" value="[ ]" /> <property name="filename" value="#{jobparameters['filename']}" /> </properties> </reader> <processor ref="contactformatter" /> <writer ref="contactspersister" /> </chunk> </step> <step id="reportbatchelet"> <batchlet ref="reportbatchelet" /> <end on="end" /> </step> </job>

23 Batch System in EAP7 Chunk step: Consist of: Reader item, Processor item and Writer item <step id="import-file-chunk" next="reportbatchelet"> <listeners> <listener ref="persistlistener" /> </listeners> <!-- The item-count specified the size of the chunk --> <chunk item-count="3"> <reader ref="recordsreader"> <properties> <!-- Define how values are separated --> <property name="separatorregex" value="[ ]" /> <property name="filename" value="#{jobparameters['filename']}" /> </properties> </reader> <processor ref="contactformatter" /> <writer ref="contactspersister" /> </chunk> </step>

24 Batch System in EAP7 Chunk step: Each item is linked to a class which implements the item interface <step id="import-file-chunk" next="reportbatchelet"> <listeners> <listener ref="persistlistener" /> </listeners> <!-- The item-count specified the size of the chunk --> <chunk item-count="3"> <reader ref="recordsreader"> <properties> <!-- Define how values are separated --> <property name="separatorregex" value="[ ]" /> <property name="filename" value="#{jobparameters['filename']}" /> </properties> </reader> <processor ref="contactformatter" /> <writer ref="contactspersister" />

25 Batch System in EAP7 Batchlet step: Batchlet is task oriented and roll your own <job id="import-file" xmlns=" xmlns:xsi=" xsi:schemalocation=" version="1.0"> <listeners> <listener ref="joblistener" /> </listeners> <step id="import-file-chunk" next="reportbatchelet"> <listeners> <listener ref="persistlistener" /> </listeners> <!-- The item-count specified the size of the chunk --> <chunk item-count="3"> <reader ref="recordsreader"> <properties> <!-- Define how values are separated --> <property name="separatorregex" value="[ ]" /> <property name="filename" value="#{jobparameters['filename']}" /> </properties> </reader> <processor ref="contactformatter" /> <writer ref="contactspersister" /> </chunk> </step> <step id="reportbatchelet"> <batchlet ref="reportbatchelet" /> <end on="end" /> </step> </job> <step id="reportbatchelet"> </step> <batchlet ref="reportbatchelet" /> <end on="end" />

26 Batch System in EAP7 JSL files can be more complex and contain Split and Decision elements which make the flow more flexible

27 Batch System in EAP7 Managing Jobs: Each record processing generates execution Instance Execution Instance holds this data: Job name Execution Id Batch current status is running / complete Exit status completed/ Failed Job start/end time Execution Execution Execution Instance Execution Execution Instance Instance Instance Instance EAP7 processing Record 1 Record 2 Record 3 Record 4 Record 5 Record 6

28 Batch System in EAP7 Managing Jobs: All execution instance data is stored in Job Repository JobOpeator Object is used as a API to the Job Repository data JobOpeator allows you to start, stop or restart jobs Data DB Job Repository Execution Execution Execution Instance Execution Execution Instance Instance Instance Instance EAP7 processing Record 1 Record 2 Record 3 Record 4 Record 5 Record 5

29 EAP7 Monitoring Data

30 EAP7 Monitoring Data EAP7 console allow us configure and see server data

31 EAP7 Monitoring Data EAP7 console allow us configure and see server data

32 EAP7 Monitoring Data EAP7 console allow us configure and see server data

33 EAP7 Monitoring Data But what about real monitoring?

34 EAP7 Monitoring Data JBoss Operation Network (JBoss-ON) is an integrated management platform that among of other activities can monitoring most of Red- Hat middleware products

36 EAP7 and IT challenges

37 EAP7 and IT challenges Market today is characterized by blurring boundaries among products and among company services, Camera are embedded into smartphones. Insurance companies are offering investment channels

38 EAP7 and IT challenges The changes leads to the fact that companies cannot rely on their old business

39 EAP7 and IT challenges Companies must be proactive in order to be relevant in the future market. Companies must prepare their IT departments to be more agile and able to rapidly update their products or services

40 EAP7 and IT challenges In order to deal with those changes, companies are adopting the DevOps culture

41 EAP7 and DevOps DevOps is a organizational culture which enables companies to deliver their releases in a short cycles, Using EAP7 Application Server enables companies to adopt the DevOps method, Lets see some DevOps characteristic and how EAP7 helps to achieve them

42 Microservices: EAP7 and DevOps A method to divide your application into some loosely coupled parts which are communicates between each other. Monolithic Web DB Application Process WebService

43 Microservices: EAP7 and DevOps Each microservice is maintained by its own releases and separate team. This approach enables small developing iterations by small team and more often deliveries. Web DB Process WebService

44 Microservices: EAP7 and DevOps EAP7 built on modular architecture enables for each microservice to loads only its modules Microservice A Microservice C EAP 7 Microservice D EAP 7 Microservice B EAP 7 EAP 7

45 EAP7 and DevOps Continues Integration and continues Delivery: CI/CD makes the building, deploying and delivering developments automated and rapid, Tools like Jenkins are used to enable CI/CD

46 EAP7 and DevOps Continues Integration and Continues Delivery: EAP7 exposed CLI (command line tool) which allow connect and manage the server by external tools, EAP7 CLI allow server configuration even the server is down.

47 EAP7 and DevOps Continues Integration and continues Delivery: EAP7 main development environment is: JBoss Developer Studio The development environment contains plugins to SCM and Maven to streamline the development process

48 Summary JBoss EAP7 is standing among the leading EE 7 application servers JBoss EAP7 along with JBoss Developer Studio has the required properties to play a role in rapid changes on the markets
