Rackspace isn't just about selling server space. It provides full spectrum of services for network infrastructure, from running a website to managing a private cloud. Since its inception in 1998 the company has transformed from a simple hosting solution to a real IT infrastructure management giant.
Traditionally many companies, including tech startups, have been choosing Rackspace as their hosting provider for its great reliability and customer service record. It's not for nothing that the company's slogan is "Fanatical support": their tech guys are really willing to go extra mile for the client.
