Deployment Patterns in Azure

There are three different deployment patterns available on Azure. They are

• Infrastructure as a Service (also popularly known as IaaS)
• Platform as a Service (also popularly known as PaaS)
• Software as a Service (also popularly known as SaaS)

The difference between these three deployment patterns is the level of control exercised by customer viz-a-viz Azure. The next image shows different levels of control within each of these deployment patterns.

It is clear from the previous image that customers have more control using IaaS deployments and it keeps reducing from PaaS to SaaS deployments.
