Many have said that 2010 will be the year of cloud computing. What this really means is unclear, just like the definition cloud computing.
Problem is that cloud computing means too many things already and the market doesn’t even exist.
The industry somewhat agreed to recognize as cloud computing just three major architectures (with examples):
- Software-as-a-Service (SaaS)
SalesForce CRM
Google Apps - Platform-as-a-Service (PaaS)
Google App Engine
Microsoft Azure - Infrastructure-as-a-Service (IaaS)
Amazon EC2
The Rackspace Cloud
