Problem?

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

• 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
