There are 5 main types of clouds in cloud computing: private clouds, public clouds, hybrid clouds, community clouds, and personal clouds. A private cloud is a dedicated infrastructure for a single organization, either on-site or off-site. A public cloud is a shared infrastructure for multiple organizations with separate data. A hybrid cloud combines both private and public clouds. A community cloud is designed for a specific community and can have various configurations. A personal cloud is dedicated for an individual user.
