Now a days Cloud hosting is the demand because it is a general term for anything that involves delivering hosted services over the Internet for small as well as to large online organizations. Cloud hosting services are divided into three main categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud was inspired by the cloud symbol that’s often used to represent the Internet in flowcharts and diagrams.

Cloud servers are the network of high configuration servers which are grouped together to maintain availability of a website by dividing the load over other servers. A cloud service has three distinct characteristics that differentiate it from the traditional hosting. Cloud hosting takes no time to setup and it is sold on demand and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.

Cloud servers can be divided into two categories which are called private cloud or public cloud. A public cloud sells services to anyone on the Internet while a private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people according to their requirements. Both the cloud platforms have their own advantages. The goal of cloud computing is to provide easy, scalable access to computing resources and IT services.

In IaaS, known as Infrastructure-as-a-Service, Cloud provides a virtual server instance API) to start, stop, access and configure their virtual servers and storage. In PaaS (Platform-as-a-service) the cloud is defined as a set of software and product development tools hosted on the provider’s infrastructure. While in SaaS (software-as-a-service) cloud model, the vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. SaaS is a very broad market. Services can be anything from Web-based email to inventory control and database processing.
