Community Cloud

A community cloud is a cloud service model that provides a cloud computing solution to a limited number of individuals or organizations that is governed, managed and secured commonly by all the participating organizations or a third party managed service provider.
Community clouds are a hybrid form of private clouds built and operated specifically for a targeted group. These communities have similar cloud requirements and their ultimate goal is to work together to achieve their business objectives. 

Community clouds are often designed for businesses and organizations working on joint projects, applications, or research, which requires a central cloud computing facility for building, managing and executing such projects, regardless of the solution rented.
C3 arises from concerns over Cloud Computing, specifically control by vendors and lack of environmental sustainability. The Community Cloud aspires to combine distributed resource provision from Grid Computing, distributed control from Digital Ecosystems and sustainability from Green Computing, with the use cases of Cloud Computing, while making greater use of self-management advances from Autonomic Computing. Replacing vendor Clouds by shaping the underutilised resources of user machines to form a Community Cloud, with nodes potentially fulfilling all roles, consumer, producer, and most importantly coordinator

The Community Source program provides industry partners with an opportunity to access VMware ESX Server source code under a royalty-free license. Partners can contribute shared code or create binary modules to spur and extend interoperable and integrated virtualization solutions. The idea is to combine the best of both the traditional commercial and open-source development models. Community members can participate and influence the governance of VMware ESX Server through an architecture board. This approach will help drive open collaboration while still preserving the ability of partners to build differentiated, intellectual property–protected solutions. For customers, the VMware Community Source program is expected to yield a richer and broader set of partner solutions that are well integrated with VMware virtual infrastructure products. For partners, the source access and development model allows
them to efficiently deliver complementary solutions or differentiated product capabilities around the VMware ESX Server code base. “More than ever standards are critical to innovation in enterprise infrastructures. Red Hat applauds the efforts of technology partners like VMware who are working to establish open, standards-based solutions,” said Paul Cormier, executive vice president of engineering at Red Hat. “We are pleased to work with VMware, partners and the community to offer customers virtualization as a key component of their open source architectures.”
