Cloud hosting, cloud computing and Cloud architecture are the latest and emerging technologies. There are many explanations of the term cloud. Many get confused between the terms of GRID and cloud computing. Cloud hosting systems are becoming more and more popular because Web hosts, most Shared hosting providers have to deal with a large number of Web sites that require a growing number of resources.
In Wikipedia you can find the best possible cloud hosting . I would like to take it as a completely new and advanced method of computer technology. The main difference that I can see that cloud computing users to purchase computer technology as a service, not a product.
Clouds can be taken as an approach for creating computer architectures and deliver services and applications to customers with scalable, virtualized resources and software resources provided as a service. The cloud can also be taken as the physical computer resources with the Internet networks.
Cloud hosting may be the most popular type of Web hosting solutions. The services could be provided on a "pay per use" basis. Cloud hosting architecture can be achieved by using the existing Virtualised and cluster technologies. A cluster of high availability (HA) that can ensure that the Web hosting services are available through the cloud would be redundant, multiple sites or Web hosting provider you want to use fail over the cluster can offer dynamically scalable resources. Clustered system is the most basic requirement of cloud hosting solutions.
Cloud hosting services are typically based on a load-balanced cluster, in which data is stored on a Storage Area Network (SAN). Any of the servers in the cluster can be easily added to or removed from the system if necessary. If any server is down for maintenance or for any other reason outside of a service, other nodes are able to handle the load.
Advantages
1 consumers exposed to using computing cycles,
2. the indicator, which measures how much processing time your hosting customer applications use,
3. they pay only for the resources they use
4. they can easily increase or decrease resources
5. Web hosts is available to any new servers deployed instantly,
6. possibility of delivery works better than Web hosting services delivered from standard servers,
7. with cloud technology, one can use a variety of technologies together into a single cloud
8. one does not need to purchase or install hardware or software every time.
