*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.
*There are many advantages of using a grid server over conventional shared hosting. The main benefit includes the reliable performance during traffic spikes or through resource usage or overload from any domain on the grid.
*Furthermore, a customer will never outgrow a grid. This is so because a new hardware can be added to it at any time to increase the web hosting capacity.
