The software consortium OW2 has opened up the working group that is creating a Cloud Stack of integrated, open source cloud infrastructure to non-members.

The group launched what it calls the OW2 Open Source Cloudware Initiative in May — a plan both to define and develop a portfolio of interoperable "open cloud" software tools to help systems integrators and hosters create fully open source cloud architectures.

"Launched" can mean many things, but the initiative actually started with some very real technology building blocks already in place. The charter group of collaborators — INRIA, Bull and France Telecom — contributed and integrated the "bedrock" of the OW2 Cloud Stack:

  • JASMINe - an open source hypervisor for virtual machine management, along with tools to manage the SOA platform, a monitoring module and a decision module.

  • ProActive - an open source provisioning and resource management tool

  • CLIF - an open source load tester that discovers the need for resources

  • Entropy - a "green computing," open source energy management tool that consolidates virtual machines for the most efficient use of power

And the star of the show:

  • JOnAS - the native implementation of OSGi and Java EE certified application server that has been one of the consortium's most successful products since its founding in 2007.

Together, those middleware applications create a solid cloud infrastructure operating at the intersection of the PaaS and IaaS layers. As a result, the OW2 cloud stack will provide autonomic elasticity at the level of the application server, not at the operating system level as most often seen with cloud infrastructure. Applications themselves grow and shrink on demand.

The working group has showcased its efforts within OW2, and has gathered contributors from around the world, from the industry and academia. Some notable examples include BUAA and CVIC from China, Talend from France and the U.S., Jaspersoft and Ingres from the U.S., Engineering from Italy, and Petals Link and BonitaSoft from France.

OW2 hopes its efforts will lead the industry toward developing a complete open source cloud architecture, from "bedrock" infrastructure up to a full suite of business applications based on open source code and open standards.
