A Private cloud is designed for the exclusive use of one organization, offering the most control over data, security, and quality of service. Public clouds are services provided over the public internet to multiple customers, and while they may offer cost savings, they do not offer the same level of control and security as a private cloud. A Hybrid cloud is an environment using a mix of on-premises, private cloud, and third-party, public cloud services. A Community cloud is shared infrastructure for a specific community with shared concerns.
