Different Types of Cloud Computing (Deployment models)
The cloud is categorized into three types
1) Private cloud: This is a type of cloud operated for a single organization only. Someone running big companies uses the private cloud, its services and infrastructure managed on a private network
2) Public cloud: When the cloud is delivered over the public network is called the public cloud. It comes free as well as with paid subscription depending upon the facilities available. As the name indicate, its services such as applications, storage, and other resources are shared by multiple customers. An example of a public cloud is Google Drive.
3) Hybrid computing: Hybrid computing is the combination of features of both public and private computing. It gives your business more flexibility and more implementation choices and other features enabling data and applications to migrate between both clouds.
