Linux used in Cloud Computing
Posted on September 23rd, 2008 No commentsCloud computing is Internet based development and use of computer technology. The cloud is a metaphor for the Internet and is an abstraction for the complex infrastructure it conceals. It is a style of computing where IT-related capabilities are provided “as a service”, allowing users to access technology-enabled services from the Internet without knowledge of, expertise with, or control over the technology infrastructure that supports them.
As of now Cloud computing can be considered to implement the following ideas :
- Utility computing – which was first suggested by John McCarthy in 1961, where computing is viewed as a public utility.
- Cluster computing - which views a group of linked computers as a single virtual computer for high-performance computing (HPC), or
- Grid computing – where the linked computers tend to be geographically distributed to solve a common problem.
