The OW2 Open Source Cloudware Initiative aims to develop an open source cloud computing stack. It involves several OW2 projects like JOnAS, JASMINe, CLIF and ProActive to provide elasticity for Java EE platforms as a service. The initiative works with Orange on a use case to improve platform efficiency and reduce energy costs through self-sizing of Java EE clusters based on workload. The goal is to attract more components to the OW2 cloud stack and position OW2 as a key player in open cloud computing through collaborative projects.

6. Starting with a real-life business
case: Orange
Context:
 Large-scale datacenters (+40,000 x86 servers)
 JavaEE JOnAS middleware stack: +250 applications,
+1,000 application server instances
 Static server consolidation (12/1) through virtualization:
• Utilization level increased from 20% to 75%
Next step: migration to a Cloud model
 On-demand JavaEE server provisioning according to
demand fluctuations
 Automation of the management of virtualized JavaEE
clusters: deployment, update, auto-scaling etc.
 Open (source) cloud management stacks alternatives
to proprietary solutions (IaaS/PaaS)
