Cloud Taxonomy

'Cloud', probably is the most over used word in the IT Industry in 2009. Big enterprises to small start-ups alike are rushing in slew of cloud based products to rake in first mover advantage. The usage of the term 'cloud' is getting muddled in the process.

I was pleasantly surprised to see a Forrester research paper on a 'Proposed Cloud Taxonomy'. Sharing the excerpts to clarify confusion around what 'Cloud' really means.

The article proposes to map all cloud flavors in the following two dimensions:
- Level of Sharing: Extent of sharing infrastructure services or business applications with other companies and tenants
- Business Value: Complexity of business process

As the diagram suggests, most of today's existing software products and services can be positioned along a level-of-sharing axis and a business value axis. The illustration uses a cloud symbol for services that will resonate as cloud services, while a squared box represents other concepts that should not be simply relabeled as cloud services.
