In Terraform, modules are the way to modularize your terraform code and make it reusable. We should not create a wrapper for every resource and call it a module. The module should be a logical group of resources that you can deploy at once.
There are a number of ways you can build a backend infrastructure on Azure such as App Services, Function Apps, etc. You can even build and deploy the entire backend on Kubernetes as well. Companies are using serverless architectures more and more for the backend. In this post, we will use a simple backend on Azure with APIM, Function App, and Cosmos DB.
