Hello to all
1) VPS is the technique of creating multiple virtual servers out of a single physical server. The single server is logically partitioned into many logical servers that can execute independently as real servers. These servers are given resources dedicated to each and they are capable of running on their OS. All features of real servers are duplicated in the virtual servers made out of them.
2) VPS offers a lot of benefits to the small and medium business men. The main advantage of VPS is the ability of each server to execute independently. The servers run on their own OS and resources. Each server has no access to the resources or software running on any other server connected to the same physical server. So when there is any problem in the working of one of the servers, the total performance is never affected. Only the affected server needs to be halted and all others continue delivering their service.
3) One of the main advantages of using VPS is the reduced cost in obtaining multiple physical servers. The expense required to get multiple resources and network can be lessened as the physical server is virtually partitioned. Each server has all the functionality of a real server but at the same time there is no need of getting the real server for use. This is mainly beneficial when the servers of architecture like mainframe are too costly to buy. There you can emulate the servers and reduce the over all expense.
4) Each server has its own share of CPU, memory and bandwidth. They need not compete for these resources. The end result is a high performance system capable of doing multiple tasks for any number of users. The virtual servers never get access to the resources of other virtual servers in the system, though they can access the physical server through proper access requests.
5) The users can install their own software in their virtual server. The update or integration of this software in no way will affect other servers in the system. Users can never look into the data existing in other servers of the system. No transparency is available to the data or resources of the servers from another server of the system. Thus privacy and security is ensured in the system.

Have a nice day
