RackSpace Cloud offer CloudServers, CloudSites & Cloud Files. The Cloud Servers are awesome. You can create servers whenever you want and pay only 1.5¢/hr. Which is great for testing sites. With Cloud Servers you get what you want when you need it. Make a new server for staging and four new servers for production. Delete one, create three more. You only pay for what you use! You can choose your own Operating System like Ubuntu, Debian, Gentoo, Centos, Fedora, Arch and Red Hat Enterprise Linux. It’s a great inexpensive alter dative to a dedicated server.
I started moving all my servers to RackSpace Cloud, It’s saving me a lot of money because all my dedicated servers were expensive since I always used RAID 1, but RackSpace Cloud Servers are RAID 10, so its cheaper and better
