Whether a public cloud or private cloud, everyone agrees that cloud computing key benefits include scalability, instant provisioning, virtualized resources and ability to expand the server base quickly.
However, “cloud computing” is still used to mean a lot of things to a lot of people. When it comes to slicing up the cloud taxonomy a little further, there’s still quite a bit of confusion between the public cloud and private cloud computing.
The public cloud is defined as a multi-tenant environment, where you buy a “server slice” in a cloud computing environment that is shared with a number of other clients or tenants.
Public clouds such as Amazon EC2 and Rackspace Cloud have a number of trade-offs:
The majority of public cloud deployments are generally used for web servers or development systems where security and compliance requirements of larger organizations and their customers is not an issue.
Private Cloud Computing, on the other hand, by definition is a single-tenant environment where the hardware, storage and network are dedicated to a single client or company.
Private cloud computing also has a number of trade-offs:
As opposed to public clouds, private clouds are not delivered through a utility model or pay-as-you-go basis because the hardware is dedicated. Private clouds are generally preferred by mid and large size enterprises because they meet the security and compliance requirements of these larger organizations and their customers.
