• Problem?
• VMware and SDKs
• Chef
• Chef and JBoss
• What’s next?
• Q&A

8. VMware and SDKs

9. VMware and SDKs
• SDKs? More than one?
– VMware vSphere Web Services SDK
– VMware VI (vSphere) Java API

10. VMware and SDKs
• VMware vSphere Web Services SDK
– Official SDK
– Supported by VMware
– Complicated
– Architecture based on
• managed objects (server)
• managed object reference (client)
• data objects

12. VMware and SDKs
• Example: VMWare Event History
• Reads the event history from VMWare
• > 100 (!!!) lines using vSphere Web
Services SDK

14. VMware and SDKs

15. VMware and SDKs
• Same example using VMware VI Java
SDK: 28 lines

16. VMware and SDKs

17. VMware and SDKs
• VMware VI Java SDK
– Open source project created by Steve Jin
from VMware R&D
– http://vijava.sourceforge.net/
– Simplify the use of VI SDK and improve the
performance
– Less lines of code, much faster, and much
more readable code

21. VMware and SDKs
• Small service implemented in Java
• SOAP-interface
• Requires JBoss 5
• Add, delete, start, stop, change
network, … etc.
• (will be upgraded to use JBoss 7,
REST, Java EE 6 soon)

23. Chef
"Chef is like a little system admin robot ...
you tell it how you want your system
configured, and it will do all the dirty
work.”

24. Chef

25. Chef
• Node:
– Any (virtual) server configured to be
maintained by a chef-client
– Chef-client runs on each node

26. Chef
• Workstation:
– Computer to run Knife
– To synchronize with Chef repo
– Interact with single Chef server
– Develop Cookbooks and Recipes
– Use Knife to upload items from Chef repo
to Chef server

27. Chef
• Knife
– Command-line tool
– Provides interface between local Chef repo
and Chef server

28. Chef

29. Chef
• Linux-installation
1. FAI (http://fai-project.org/) for basic setup
2. Chef for additional APT-packages
3. Chef for middleware installation

30. Chef and JBoss
Java Magazin 11.12:
Automatisierung nach Chef-Rezept
Automatisiertes Deployment von
JBoss Middleware

31. Chef and JBoss
• Automatic deployment of JBoss application
server using Chef
• Components:
• JBoss EAP 5/6 preconfigured in SVN
• JBoss Operations Network (JON): Monitoring-
solution for e.g. JBoss
• JON Agent: Agent scanning JBoss-processes
• Remote-CLI: CLI running JavaScript-files
accessing the JON-API

32. Chef and JBoss

33. Chef and JBoss
Autodiscovery
Queue

34. Chef and JBoss
• JON/RHQ has a remote API
– JON/RHQ-CLI with JavaScript-files
– JON/RHQ-JARs with Java
• Executing JavaScript-files using the
CLI:
– rhq-cli.sh –f import-servers.js
-s ${RHQ_SERVER} –u user –p pwd

35. Chef and JBoss
1. Import JON-Agent
2. Import JBoss EAP 5/6
3. Change settings

41. Chef and JBoss
And Clustering?

42. Chef and JBoss
• UPD: Just works!
• TCP
– Move cluster-config from XML to
Properties-file
– Use Chef to modify Properties-file
