Sascha Möllering discusses infrastructure as code and provides an overview of VMware SDKs, Chef, and using Chef to configure JBoss middleware. He explains that VMware has multiple SDKs and that the VI Java SDK simplifies development. Chef is introduced as a tool to automate and standardize server configurations. The presentation then covers using Chef recipes to deploy and configure JBoss application servers and integrating with JBoss Operations Network for monitoring.

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

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
