The "lift-and-shift" approach with Azure IaaS can only deliver on small measure of the promise of agility and innovation in the Cloud when compared to modernized application (i.e., Cloud-optimized). Modernizing application with Azure PaaS, on the other hand, can deliver on the promise of agility and innovation to a great extent. It reduces the time required to manage the application and the time required to deploy a new release, and optimizes the speed to market.
