Community cloud shares infrastructure 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.
Benefits of Community Cloud Model

Community cloud offers same advantage as that of private cloud at low cost.
Sharing Between Organizations-
Community cloud provides an infrastructure to share cloud resources and capabilities among several organizations.
Security-
Community cloud is comparatively more secure than the public cloud.
Disadvantages of Community Cloud Model
Data accessible between Organizations-
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.
Challenging in Responsibilities-
It is also challenging to allocate responsibilities of governance, security and cost.
