A cloud server is primarily an Infrastructure as a Service (IaaS) based cloud service model. There are two types of cloud server: logical and physical. A cloud server is considered to be logical when it is delivered through server virtualization. In this delivery model, the physical server is logically distributed into two or more logical servers, each of which has a separate OS, user interface and apps, although they share physical components from the underlying physical server.
Cloud hosting is a network of servers in multiple locations, which share data and resources among themselves. That reduces server load and increases performance. As the demand rises, clients can easily scale their plans. By doing so, they increase the performance of their cloud hosting in just a few clicks. Now, it’s quickly becoming more and more popular.
Cloud hosting is an alternative to hosting websites on single servers (either dedicated or shared servers) and can be considered as an extension of the concept of clustered hosting where websites are hosted on multiple servers. With cloud hosting, however, the network of servers that are used is vast and often pulled from different data centres in different locations.
