Cloud Hosting hello friends,
my question is if some one want to start a web hosting company, then what are the server requirements for that. i means how many servers(linux servers only) are required and what software or servers packages needs for that. also whether i have to install different servers for different servers packages like mail, HTTP, proxy etc.
also is there another methods for servers like cloud(what is cloud computing, i studied that but not understand what it is)
if there some reference or manuals having brief about these, please also paste.
Chosen Answer:
Start small and gradually grow. Two minimum: 1=mail and web, 2=DNS. Pack as many hosts as you can on a server.
FYI, there are tons of competition for web hosting so you need something to give you that extra edge, whether it’s excellent customer service or uptime or user-friendly cpanel. Keep in mind that you’ll have to deal with lots of issues, eg spammers, phishing, copyright, network attacks.
Cloud computing is using multiple servers to act as one whole unit–the cloud. Everything is transparent to the end user. A good example is Google Apps. Log on to your GMail and you’ll see a calendar and other goodies. Amazon has one too but there’s a fee.
If you’re interested, you can try Eucalyptus. It’s included in Ubuntu 9.04 and above as Ubuntu Enterprise Cloud. Two minimum.

I like your enthusiasm about it – just jump right into it. I depends how many sites you plan to host and how busy you expect them to be. It is probably safe to say that virtual computing is the way to go. For that you need powerful servers that can handle many virtual machines simultaneously. I want to stress out, however, if you are so fresh to this business, that you don’t even know how to go about it, you might want to get some first hand experience before you start spending money.
Posting these questions says that you lack about 5 years of experience you’ll need to run a web hosting company. Work for one before you try to start one. (Like, do you have the money to pay the staff you’ll need for at least 3 years, before you show a profit? [You're not going to provide 24/7/365 tech support all by yourself. To 5 people calling at once.])
