The private cloud on other hand offers more control in an on-premise environment. The management part falls into organization hands and in this, the users are individually responsible for security and performance monitoring.

Hybrid Cloud is best of all three as it offers the best of both the clouds. In other words, a mixture of both public and private cloud. There can also be minor performance issues but these are always lesser than the other two types of cloud.
