What is Cloud Computing?

Cloud Computing is a technology that uses the internet for storing and managing data on remote servers and then accessing data via the internet.

Cloud computing customers do not own the physical infrastructure; they rent usage from the third party provider.

There are four types of Cloud computing

Public clouds are cloud environments that are created from IT infrastructure not owned by the end user.


Private clouds are cloud environments that are dedicated to a single end user or group, where the environment usually runs behind that user or group’s firewall.


A hybrid cloud is a cloud environment that is created from multiple environments connected through LANs (Local area Networks), WANs (Wide Area Networks ), VPNs(Virtual private Networks) and/or APIs.


Multi Clouds are made up of one cloud services, from more than cloud vender-public or private


All Hybrid Clouds are Multi Clouds, but not all Multi Clouds are Hybrid Clouds.
