What is a Community Cloud?

A community cloud in computing which is a collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns (security, compliance, jurisdiction, Banking, Government, etc.), whether managed internally or by a third-party and hosted internally or externally.This is controlled and used by a group of organizations that have shared interest. 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.
