Cloud computing is fast becoming one of the most popular computer models for businesses worldwide. The efficiency, availability, and accessibility of the virtual server infrastructure at all times, the familiarity of the web-based interface, and the almost endless scalability of the cloud-based architecture have contributed significantly to its rapid introduction.
Despite its many advantages, many companies still have many questions about cloud computing and how best to meet their specific needs. One of the most important questions organizations need to ask is which cloud is best for them.
There are two types of clouds: public cloud and private cloud. The third type, known as a hybrid cloud, is simply a combination of the two.

A public cloud, also known as a shared cloud, is a cloud in which virtual computing services are publicly available via the internet, with little or no control over access or core infrastructure.
The benefits of a public cloud include reduced software, hardware, and management complexity, as well as fewer delays and costs in developing internal applications. Public cloud resources are shared online.
A private cloud (also known as an internal cloud or an enterprise cloud) provides virtual computing services that are sent over a private intranet or company-hosted data center. It is an application or controlled-access network that provides an in-house computing solution where resources are purchased, installed, and maintained on-site.
