The community cloud allows system and service to be accessible by group of organizations. It shares the infrastructure between several organizations from the specific community.It may be managed internally or by the third- party
A community cloud is a multi-tenant infrastructure that is shared among several organizations from a specific group with common computing concerns. Such concerns might be related to regulatory compliance, such as audit requirements, or may be related to performance requirements, such as hosting applications that require a quick response time
The goal of a community cloud is to have participating organizations realize the benefits of a public cloud -- such as multi-tenancy and a pay-as-you-go billing structure -- but with the added level of privacy, security and policy compliance usually associated with a private cloud.
The community cloud can be either on-premises or off-premises and can be governed by the participating organizations or by a third-party managed service provider
Features and Benefits of community cloud
Sharing Between Organizations: Community cloud provides an infrastructure to share cloud resources and capabilities among several organizations.
Cost Effective: Community cloud offers same advantage as that of private cloud at low cost.
Security: Community cloud is comparatively more secure than the public cloud.
Since all data is housed at one location, one must be careful in storing data in community cloud because it might be accessible by others.
It is also challenging to allocate responsibilities of governance, security, and cost.
