On Azure, three of the most obvious choices for Infrastructure as Code are Bicep, Terraform, and Pulumi. Bicep is Microsofts own domain-specific language, whereas Terraform is the open-source tool being cloud agnostic. Where Bicep and Terraform both have their own language, Pulumi allows you to write your Infrastructure as Code using your favorite language like C#, Python, or Go. In this session, we will discover where they are similar and where they are not and see their pros and cons. We will look at the ecosystems for these tools to see how well they integrate with other tools like security scanners and CI/CD pipelines. At the end of this talk, you can make a well-founded decision on which tool to use in your next project!
