I'm wondering if this is possible. Cloud hosting, as I understand, utilizes different servers for just one website. What I'm thinking on this one is having like 2 or 3 dedicated servers for only one website.
In my opinion, there is one more option available in such case. You should opt load balanced server hosting environment to cope up your website operation. In load balancing cluster of servers with the same functionality, which helps to distribute the load among themselves in order to accomplish serer scalability, high availability and fail-over and so forth.
Its all nice replies and i am glad to read all. one website and multiple facilities are possible. you can create one website for multiple work. And it is also possible that one website can be multipurpose. that means it can do work of four website. Such as software of traffic system can be same in every city and software for retail counter for same company having multiple branches in different cities is also possible.
