Transcription

1 The future of middleware: enterprise application integration and Fuse Giuseppe Brindisi EMEA Solution Architect/Red Hat

2 AGENDA

3 Agenda Build an enterprise application integration platform that is: Resilient Maintainable Flexible With high performances

4 What is EIP?

5 What is EIP? Work by Hohpe / Woolf Became a de facto standard speak the same language reuse of know how and solutions Avoid custom code for integrations performance, bugs, less lines of code

6 Enterprise Integration Patterns

7 What's JBOSS Fuse?

8 What's JBOSS Fuse? An integration Middleware built on: JBoss AMQ (ActiveMQ) for messaging Camel for mediations (routes) CXF for Web Services Fabric for governance (registry, provisioning) many minor subcomponents

9 What is Jboss FUSE?

10 What is OSGI?

11 What is OSGI? A standard for a Modular Java how to pack code in a bundle (jar) OSGi bundles can be remotely installed, started, stopped, paused, updated and more (Lifecycle Management) OSGi = SOA in a JVM First version in 2000, coming from the telco world.

12 What is Camel?

13 What is Camel? Framework Open source implementing EIP patterns mapping 1:1 between pattern and components camel routes managed through OSGI OSGI Container OSGI : Container = EJB : J2EE Server

14 What is Camel?

15 What is ZooKeeper?

16 What is ZooKeeper? Part of the Hadoop ecosystem Used to build coordination logics Sharding, Failover, Discovery, Master election, ecc. Used by HBase, Kafka, Solr, Yahoo, etc.

17 What is MAVEN?

18 MAVEN Maven is the de facto standard in Java dependency management Nexus (Artifactory) is a centralized Maven repo that makes Devops easy controls dependencies a server contains each and every project artifact

19 What is KARAF?

20 What is KARAF? Lightweight container for OSGI Hot deploy, logging, shell, configuration, provisioning services JEE component : JBoss = bundle OSGI : Karaf

21 What is ACTIVE-MQ?

22 What is ACTIVE-MQ? Open Source Messaging Broker JMS, AMQP, MQTT, OpenWire, STOMP, REST Java, C, C++, C#, Ruby, Perl, Python, PHP Pluggable Transport in-vm, TCP, SSL, NIO, UDP, JGroups

23 What is CXF?

24 What is CXF? De facto open source standard for Web Services Used in JBoss too WS-*, REST support

25 What is Fabric?

26 What is Fabric? Allocate Resources, Install & Connect containers in your environment Publish Services, Discover & Coordinate Manage Provision Visualize Scale Up / Down and much more

27 What is Fabric? Introduced with Fuse technology But now an independent project It is now (will be) cross product (Fuse, EAP, Openshift, ecc.)

28 What is Fabric? Provisioning configurations, scripts, code (aggregated in profiles) On every kind of container Karaf, Wildfly, Tomcat, plain JVMs Everywhere Openshift, Docker, any public/private IAAS, bare metal, hybrid.

29 Example Architecture

30 Example Architecture

31 Architecture: Camel node details

32 The Console

33 The Console: Hawt.io camel route view

34 The Console: command line console Fuse Command Line console SSH based Total local and remote control of the system Scriptable

35 The Console: command line console

36 Performance

37 Performance - CAMEL Camel is a Java technology and doesn t introduce any overhead Performance depends by the Camel components used provided components has usually been finely tuned and tested in hundreds of customers Camel code is probably much faster than your code ;)

38 Performance - ActiveMQ AMQ persistence File system based LevelDB, a nosql developed by Google O(1) to load stored messages thanks to the BTree Google algorithm 3 or persistent messages instantaneously loaded by a broker.

39 Performance - ActiveMQ LevelDB has excellent write performance Disk speed is the single most important factor. About 10k msg/sec (5kb) of sustained traffic on a modern laptop with an SSD About 4.5k msg/sec (5kb) of sustained traffic on Amazon server (9k msg/sec using both disks)

40 High Availability and Scalability

41 High Availability and Scalability HA AMQ can be configured in Master - Slave 1 Slave per 1 Master N Slaves per M Masters (example: 2 Slaves per 10 Masters) Scalability AMQ can scale horizontally with different topologies: Network of Brokers Client side partitioning

42 Conclusions

43 Conclusions Resiliency Distributed Architecture Failover Master/Slave for High Availability Horizontal Scalability: Network of Brokers, Client side partitioning Maintainability OSGI based, standardized software component lifecycle (with versioning) Powerful admin console Performance

50 Software Development Process

51 Software Development Process Integration requisite If tag A contained in Message M has in corresponding record in table B the X field Trasform M (remove t1 tag, add X tag) Add tag t3 to Message M in any case

52 Software Development Process Translation in Enterprise Integration Patterns

53 Software Development Process

54 Software Development Process Transform EIP in code using a DSL in Java using a DSL in XML with a GUI editor (Eclipse plugin)

55 Software Development Process Bundle in an OSGI component mvn install Push on Maven/Nexus repo mvn deploy

56 Software Development Process With CLI console or Web Console, and following Roll-out company plan, pull the bundle from the repository Selected containers will download and start automatically the bundle

57 Software Development Process Canonical process is: create a new route implementing business pack the route in a bundle and assign to a new version of a profile upgrade one of more containers to this profile to check everything is ok roll-out on every container or roll-back

58 Software Development Process DEFCON 2 process: Open the web console on a production server edit the route on the fly
