It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

Generally, yes you need at least two servers. But with services like Amazon EC2, Rackspace, Softlayer, Slicehost etc. it's easy to set up lots of small, inexpensive servers, or with CloudWatch and similar services it's possible to only have one server running at any time but have a 'live image' avaliable so when the server goes down you can start a new instance from that image and your application can continue running. Although often there will be some downtime, maybe a few seconds, while the applications switch over. | |||
