We usually use a single server only in traditional hosting services. When a website is allowed to have access to multiple servers, this is called cloud hosting or clustered hosting and can mean unlimited processing power as 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. Through this cloud technology, easy integration of extra resources such as space or RAM can be achieved and thus enable website growth. When a UK VMware host service is delivered from a fully redundant, multi-server system wherein the resources are usually virtualized and dynamically scalable, this is generally considered a cloud technology. 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. Sites get resources from other servers as servers can easily be added or even removed as necessary whenever a server goes down. The providers or so-called cloud hosts then measure or compute the amount of processing time an application uses. Bills are then provided and made. It is a different service model than that used by other web hosting services and clients pay for actual resources needed. The service model used is different from that of other web hosting services and clients pay for resources actually needed. A lot of advantages are derived from this type of web hosting. You can easily add or remove resources without moving websites to different servers; you pay only for actual resources needed; you have more up time than other web hosting services; any traffic spikes are easily handled by the cloud; and any or all hassles of installing software or hardware are avoided by just connecting to a cloud that has the software or hardware you need. This is recommended for the following cases even though it is suitable for many web applications: Resource-wanting applications: If the application needs more power and more memory to run, this is used. When occurrences of some cases where only certain applications needed longer timeout for successful completion of the job, this is used. Using multiple servers becomes the most cost effective solution to this case. Making sure that there are enough resources accessible to middle level users is one of the jobs of a cloud host. In a forum of 100,000 users with more than a hundred members going online at the same time, the cloud should be able to handle the traffic without any problems at all. 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 this particular case, cloud servers can be used and configured in every way to fulfill and accomplish any specific requirements.
