Normally, we use a single server only in traditional hosting services. A cloud host (also called clustered hosting) allows a website to have access to multiple servers which translates to unlimited processing power wherein a new server can always be added. Permitting or allowing unrestricted number of machines to act as one system is the basis of one of the most innovative cloud computing technologies. The hosting security is guaranteed by many servers compared to some other hosting solutions; it may be shared or dedicated and is better than dependence on one machine. To enable website growth, simple integration of extra resources such as space or RAM can be achieved through this cloud technology. In general, however, a VMware hosting service can be considered cloud technology when it is delivered from a fully redundant, multi-server system, in which the resources are dynamically scalable and often virtualized. This technology uses a number of servers that are connected together (a cloud), and any or all sites that are on the servers can use the resources from all the servers in that cloud. Processing power, hard drives and memory are some of the things shared through this connection. Whenever a server suffers downtime, sites can get resources from other alternative servers since these can be added easily or removed as deemed necessary. The providers or so-called cloud hosts then measure or compute the amount of processing time an application uses. Cycles of processing time the application requires or uses are computed or measured by the cloud hosts or providers. This is then billed upon notice, Getting this type of webhosting gives you many advantages. You pay only for the resources you need; you can easily increase or decrease resources without moving sites to other servers; you get better up time than other web hosting type; the cloud can handle any traffic spikes; and you avoid all the hassle of installing hardware or software by simply connecting with a cloud that has the hardware or software you need. Payment is only for resources needed; resources may be easily added or removed without having to move sites to other servers; the cloud can handle any kind of traffic; better up time than other web hosting types can be achieved; and hassles that come with installation of hardware or software are minimized by simply connecting to a cloud that had your required hardware or software. This is recommended for the following cases even though it is suitable for many web applications: Resource-hungry applications: It is used if the application calls for more power and memory to run. There are some cases where only a certain application option may need longer timeout for the job to be successfully completed. If this happens, your most affordable solution is to operate multiple servers. Making sure that there are enough resources accessible to middle level users is one of the jobs of a cloud host. A sample would be a forum of hundreds of thousands of users wherein hundreds maybe online at the same time must and should be handled by the cloud host without any difficulty. Applications requiring special server configuration: Some web applications like for example, PHP running as Apache module will usually require non-standard settings or in this case not those used by the shared hosting industry. In such cases, cloud servers can be configured to accommodate a variety of settings requirements.
