PRIVATE VS PUBLIC VS HYBRID CLOUD


Private Cloud :-

Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service . A private cloud is dedicated to the needs and goals of a single organization. It is also known as Internal or Corporate Cloud .




Public Cloud :-
A public cloud is where an independent, third-party provider, such as Amazon Web Services  and maintains compute resources that customers can access over the internet. Public cloud users share these resources, a model known as a multi-tenant environment.




Hybrid Cloud :-

 A hybrid cloud is a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them. It delivers the private cloud’s high- security features coupled with the fast connection and easy-to-access features of the public cloud.
