Shared Hosting means that one physical server and its available resources hosted are shared among many users. Actually, on the shared hosting each customer or user has his own limit on particular services usage like disk space, monthly traffic, bandwidth, email accounts, FTP accounts, databases etc. On the other hand, all resources on a physical machine which we called server are shared. The RAM and CPU, Apache server, MySQL server and the Mail server are on a shared basis. It is the most economical for hosting a website simply because expenditures per machine are covered by more users.

VPS Hosting:

A virtual private server (VPS) is a virtual machine. A VPS runs its own copy of an operating system, and customers may have super user-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPS’s, performance may be lower, depending on the workload of any other executing virtual machines.
