What is Public Cloud?

A cloud is known as ‘Public Cloud’ when the services are rendered over a network architecture that is open for public use. It is based on the standard cloud computing model, in which a service provider offers on-demand computing resources such as application and storage, available to the general public via internet. Public cloud services may be free, or delivered on a pay-per-usage basis. In simple terms, it provides an on-demand solution, where one can choose to store their data in a public cloud which implies that users can use the resources of an off-site third party service provider. Payment for the physical computing resources is made on pay per usage basis, much like a utility based service. There is no upfront cost associated with this model including hardware, software licensing, etc.

Significant benefits of using a public cloud include the following:

• Easy and inexpensive set up cost
• Scalability to meet the dynamic needs
• Pay per usage resource delivery
