When we are talking about cloud servers and virtual servers, there are some differences between both of them. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic and utility computing. Details are abstracted from end-users who no longer have need for expertise in, or control over, the technology infrastructure “in the cloud” that support them. The underlying concept of cloud computing dates back to the 1960s, when Jhon McCarthy opined that “computation may someday be organized as a public utility.” Almost of the modern-day characteristic of cloud computing (elastic provision, provided as a utility, online, illusion of infinite supply), the comparison to the electricity industry and the use of public, private, government, and community forms. By switching traffic to balance utilization as they saw fit, they will able to utilize their overall network bandwidth more effectively.
A server, usually web server, that shares computer resources with other virtual servers. In this context, the virtual part simply means that it is not a dedicated server-that is, the entire computer is not dedicated to running the server software. Virtual web servers are a very popular way of providing low-cost web hosting services. Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same computer. In most cases, performance is not affected and each web site behave as if it I being served by a dedicated server. However, if too many virtual servers reside on the same computer, or if one virtual server starts hogging resources, web pages will be delivered more slowly.
