community cloud [English]
n. ~ A cloud infrastructure deployment model in which a specified group of organizations with common privacy, security, or legal concerns, collaborate to share resources that may be managed by the organizations or a third party, on or off premises.
- Gartner IT Glossary (†298 s.v. "community cloud"): A shared cloud computing service environment that is targeted to a limited set of organizations or employees (such as banks or heads of trading firms). The organizing principle for the community will vary, but the members of the community generally share similar security, privacy, performance and compliance requirements. Community members may wish to invoke a mechanism that is often run by themselves (not just the provider) to review those seeking entry into the community.
- NIST 2011B (†415 p. 21): The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise. (Source: NIST CC Definition)
- Duranti 2013 (†408 ): A community cloud infrastructure is shared by two or more organizations with common privacy, security, and regulatory considerations. It may be managed by the organizations or a third party, and may be hosted internally or externally. (†484)
- Furht and Escalante 2010 (†583 p.339): The idea of a Community Cloud is derived from the Grid Computing and Volunteer Computing paradigms. In a community cloud, several enterprises with similar requirement can share their infrastructures, thus increasing their scale while sharing the cost (Wikipedia – Cloud Computing, 2010). Another form of community cloud may be established by creating a virtual data center from virtual machines instances deployed on underutilized users machines (Briscoe & Marinos, 2009). (†1174)
- McLelland, et al. 2014 (†403 8): The final type of cloud is referred to as a “community cloud,” where a specified group of clients all share the same cloud service. In this way, the clients can ensure that their information is not being stored with other unknown organizations but can still gain the purported benefits of sharing the burden of cost. This implementation could also enable information sharing between organizations with shared interests or data uses. [Text includes citations] (†454)
- Stancic, Rajg, and Milosevic 2013 (†904 p. 111): Where the physical infrastructure is implemented, administered, and operated by several organizations in a certain community of consumers from organizations that have shared goals and requirements. (†2722)
- Wikipedia (†387 s.v. "Community cloud"): A community cloud in computing is a collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally. The costs are spread over fewer users than a public cloud (but more than a private cloud), so only some of the cost savings potential of cloud computing are realized. (†455)
