You can’t read a technical Web site these days without some mention of so-called cloud computing. Cloud computing gives users access to massive computing and storage resources without them having to know where those resources are or how they’re configured. This article discusses the anatomy of cloud computing and how Linux and the open source community contribute to the world of cloud computing. As you might have guessed, Linux and open source technologies play a huge role.
Is there any cloud-computing available that isn’t running on Linux ?
Probably not. The problem with any sort of cloud computing is is, by its nature, almost impossible to quantify and that means that you cannot be restricted by the technology or by licensing. As such, and open source system is pretty much the only ideal fit and companies like Microsoft would quickly see their steady revenue streams threatened unless they built in restrictions into their offerings.
