The updating capability is the most important feature of Azure Blueprint.
In a traditional infrastructure setting, a solution is deployed into a predefined infrastructure environment. Then it basically remains untouched for the remainder of the solution’s lifetime. With Azure PaaS, the fundamental conditions are different, and this opens new opportunities. The services the infrastructure is based on, are constantly expanded and improved. These ranges from new dashboards and monitoring points, to introduction of new VM types, which supersede older ones with better performance at the same price, to security features and much, much more.
As a Blueprint customer the end result is that you are always running on the best available services, making the most of the cloud without even having to intervene.
