Manage Java Applications in an Open Hybrid Cloud

  1. 1. 1 Manage Java Applications in an Open Hybrid Cloud John Doyle Senior Product Manager 18 June 2013
  2. 2. 2
  3. 3. 3 What is a cloud-ready architecture ● High degree of Automation ● Flexible Management ● Frugal Use of Resources ● Open Platform PHYSICAL VIRTUAL PRIVATE PUBLIC JBOSS ENTERPRISE MIDDLEWARE
  4. 4. 4 Automation
  5. 5. 5 JBoss EAP 6 Standalone Architecture ● Preserved simplicity from earlier JBoss EAP versions ● Server Instance is the Unit of Automation ● Enhanced by EAP 6 Management APIs
  6. 6. 6 JBoss EAP 6 Distributed Domain Architecture ● Domain ● DomainController ● HostManager ● ServerGroup ● Cluster
  7. 7. 7 Flexible Management
  8. 8. 8 Management Options ● JBoss EAP Command Line Interface (CLI) ● Graphical Console ● Native Java Interface ● JBoss Operations Network (JON) ● HTTP/REST Interface ● Direct XML Editing
  9. 9. 9 JBoss EAP 6 Management : jboss-cli ● Transactional Interactive Client ● Connects to Standalone Instance or Domain Controller ● *nix based shell syntax, resources as files ● Contextual command and resource tab-completion ● High-level compound operations ● Persistent Changes [standalone@localhost:9999 /] cd subsystem=datasources [standalone@localhost:9999 subsystem=datasources] cd data-source=ExampleDS [standalone@localhost:9999 data-source=ExampleDS] :flush- flush-all-connection-in-pool flush-idle-connection-in-pool [standalone@localhost:9999 data-source=ExampleDS] :flush-all-connection-in-pool {"outcome" => "success"} [standalone@localhost:9999 data-source=ExampleDS]
  10. 10. 10 JBoss EAP 6 Web Console ● Simple ● Fast ● Lightweight ● Avoids XML Editing ● Single Instance and Domains ● Mostly Configuration ● Basic monitoring ● Not a JBoss ON replacement
  11. 11. 11 JBoss EAP 6 Native API ● Native API Sample ModelNode op = new ModelNode(); op.get("operation").set("read­resource­description"); ModelNode address = op.get("address"); address.add("subsystem", "web"); address.add("connector", "http"); op.get("recursive").set(true); op.get("operations").set(true); ● CLI Equivalent [localhost:9999 /] /subsystem=web/connector=http:read­resource­ description(recursive=true,operations=true)
  12. 12. 12 JBoss Operations Network – Advanced Manageability ● Central Management and Monitoring ● Multiple Products / Versions ● Configuration Management ● Responsive Provisioning / Deployment ● Performance and Availability Management ● Custom Dashboards
  13. 13. 13 Frugal Use of Resources
  14. 14. 14 EAP6 Core Architecture
  15. 15. 15 Traditional Application Server Classloading
  16. 16. 16 Module Class Loading <module name=”com.bananodyne”> <main-class name=”com.bananodyne.Main”/> <resources> <resource-root path=”mymain.jar”/> </resources> <dependencies> <module name=”org.slf4j”/> <module name=”javax.api”/> <module name=”org.junit”/> </dependencies> </module> <module name=”com.bananodyne”> <main-class name=”com.bananodyne.Main”/> <resources> <resource-root path=”mymain.jar”/> </resources> <dependencies> <module name=”org.slf4j”/> <module name=”javax.api”/> <module name=”org.junit”/> </dependencies> </module> Peer-to-peer delegation Cyclical Graph Similar to IDE “projects” or “modules” JDK split into modules NOT TRANSITIVE
  17. 17. 17 Performance – Boot-time / Footprint Cold Boot Time Cold Boot Memory
  18. 18. 18 Open Platform
  19. 19. 19 Open Platform ● Open Standards are essential for the success of the Open Hybrid Cloud. ● Open Standards form the links between the Datacenter, Private Cloud, and Public Cloud. ● Open Standards are the DNA of Red Hat and JBoss. ● Adopt Open Standards whenever possible. ● Create new technology and drive to standards when possible. ● SEAM -> CDI ● Hibernate -> JPA
  20. 20. 20 EAP in the Cloud
  21. 21. 21 JBoss EAP in Red Hat OpenShift
  22. 22. 22 JBoss EAP in Red Hat Cloud Forms
  23. 23. 23 JBoss EAP with Red Hat Cloud Access
  24. 24. 24 JBoss : EAP 6 Distributed Domain Architecture ● Domain can span environments. ● Secure management connections with SSL or TLS ● JON can also manage and monitor hosts on EC2 EC2 OnPremise
