An Azure App Service Plan is the best example of the PaaS model in Microsoft Azure. It allows us to host applications without servers and virtual machines. Even though management options are simplified and cut down to the minimum, we still have a lot of configuration options. Legacy support is next to nothing, but the PaaS model is intended for modern applications that require the latest features and frameworks. If you need to run legacy software, IaaS is the best choice.
We introduced IaaS and PaaS in Azure from the application perspective. But the application is nothing without data. In the next chapter, we'll move to Data Platform in Azure and show how to create and manage databases in the cloud.
