By focusing on AWS, for example, we have Cloudformation or the most recent AWS CDK, just to name a few. But if we wanted a tool that provides a flexible abstraction of resources and providers, the choice would almost certainly fall on Terraform. …


Often we happen to have to use customized AMIs based on our needs and having to create them based on the operating system and programs required. But if instead of doing this just for us, we had to do it for our customers and what if we have many customers?
