The terms “Shared Cloud” and “Shared Cloud Hosting” are not very different from Cloud Hosting. They also refer to an Internet Hosting service delivered from a group of servers. The term Shared Cloud Hosting (Shared Vloud) is not precisely defined yet. However, a “Shared Cloud Hosting” could be considered a service delivered from a computer system in which the computing resources (processing resources) are distributed. To be considered as “Shared” any Cloud hosting service must be powered by a software platform which does not create isolated virtual instances. In a Shared Cloud, all data resides in a shared storage system or network (shared pool). Cloud accounts (name based or IP based virtual hosting) share the computing resources of all servers part of the system.
