Grid web hosting may seem similar to shared web hosting; however, there is a slight difference between the two. While shared hosting implies that hundreds of web sites share one server, grid web hosting means that hundreds of web sites on one server share the same bandwidth and storage provided by other servers.

*Grid web hosting is not a very new development as it sounds. Many business organizations have been using grid hosting for about a decade.
*There are some business organizations who have refined local clusters to run anywhere from a single user and venture to global networks that handle several projects and users.
*The research that is behind the commercialization of the grid server has emerged from all this earlier research.
*The grid server provides great redundancy. It has been designed to endure frequent hardware and software failures.

HI NIle,

Nice post. Keep on sharing with us.

Grid hosting generally means that the web extension you hear is not detect on one machine, but is  same as  a "virtual machine"  which is hosted on a collection of servers.
