*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.
