Grid web hosting
It is a special type of web hosting service and all the computers are interconnected via common server. The performance of the internet depends on the type of hardware on which the server is running. In grid hosting all the resources on the various computers that are connected with server are placed in the form a grid and hence it is called grid hosting. It is the process where the problem is separated and divided into chunks and distributed to multi computers and the grid hosting helps in finding a solution to the problem.
When the web site on the grid hosting becomes popular you can add more computers to it. And in grid hosting the hardware things are distributed and the works like email serving etc are distributed to various computers. It prevents the problem of site traffic. On installation of new server there is no problem of down time or any uplink problem. In case of crash, there is chance for replacement of server and during migration it is easy to mix up those servers and the resources on the servers. The applications on the various servers do not conflict with each other and it is much better than the shared webhosting.
