Author’s Note: This post was revised on 6/23/08. The nature of computing is under going a revolution and rather than fully remove this post, I elected to refresh it so as to provide a better framework for readers.
There seems to be a lot of debate around different types of Computing Terms being used to describe server and hosting solutions. In fact, in the past, the blogosphere seemed to throw around terms like Grid, Cloud, Utility, Distributed and Cluster computing almost interchangeably. But, as of this revision, one term is rising to the top: Cloud Computing. (See recent trend analysis here.)
The definitions vary from source to source, author to author. While I cannot (and will not) attempt to articulate the end-all definition, I can write about how I view these terms and how they apply to the products that we offer, namely GoGrid. But before I dive into MY interpretation, providing what others view on these subjects may shed some light on our framework.
Terms as defined by Wikipedia
Many people view Wikipedia as an authoritative source of information but that is always subject to debate. Wikipedia defines some of these terms as follows (not the end-all definitions though) and I have taken some liberties of removing non-relevant information for argument’s sake:
- Grid Computing – http://en.wikipedia.org/wiki/Grid_computing
- Multiple independent computing clusters which act like a “grid” because they are composed of resource nodes not located within a single administrative domain. (formal)
- Offering online computation or storage as a metered commercial service, known as utility computing, computing on demand, or cloud computing.
- The creation of a “virtual supercomputer” by using spare computing resources within an organization.
