VMware and SDKs
VMware and SDKs
• SDKs? More than one?– VMware vSphere Web Services SDK– VMware VI (vSphere) Java API
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
vSphere server
VMware and SDKs
VirtualMachineManaged
object
GuestInfodata object
vSphere client application
Managed object reference to a
VirtualMachine
GuestInfodata object
data objects
network connection
VMware and SDKs
• Example: VMWare Event History• Reads the event history from VMWare• > 100 (!!!) lines using vSphere Web
Services SDK

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

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

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)
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.”
Chef
Chef
• Node:– Any (virtual) server configured to be
maintained by a chef-client– Chef-client runs on each node
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
Chef
• Knife– Command-line tool – Provides interface between local Chef repo
and Chef server
Chef
Chef
• Linux-installation1. FAI (http://fai-project.org/) for basic setup
2. Chef for additional APT-packages
3. Chef for middleware installation
Chef and JBoss
Java Magazin 11.12: Automatisierung nach Chef-Rezept Automatisiertes Deployment von JBoss Middleware
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
Chef and JBoss
Chef and JBoss
JON-Server 3.1
Remote-CLI
JBoss EAP 5/6
JON-Agent
Knife
AutodiscoveryQueue
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
Chef and JBoss
1. Import JON-Agent
2. Import JBoss EAP 5/6
3. Change settings

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