Cloud
computing is typically classified into three ways:
1. Public Cloud
2. Private Cloud
3. Hybrid Cloud
- Public
cloud:
In Public cloud the computing
infrastructure is hosted by the cloud vendor at the vendor's premises. The
customer has no visibility and control over where the computing infrastructure
is hosted. The computing infrastructure is shared between any organizations.
- Private
cloud:
The computing
infrastructure is dedicated to a particular organization and not shared with
other organizations. Some experts consider that private clouds are not real
examples of cloud computing. Private clouds are more expensive and more secure
when compared to public clouds.
- Hybrid
cloud:
Organizations may host
critical applications on private clouds and applications with relatively less
security concerns on the public cloud. The usage of both private and public
clouds together is called hybrid cloud.
