Writing the code for an application is an entire project, and then automating cloud resources with Infrastructure as Code (IaC) is another entire project on top of that. Writing IaC means you have to know what services the application needs, plus knowledge of the cloud provider hosting the app. Finally, you need to know the toolset you're using to provision the cloud infrastructure.

As developers, IaC usually doesn't fall on us, but we're the ones creating the application. We should be able to automate the creation of cloud resources our applications need. And we should do it with code, the best way we know how.

Let's discuss what IaC is. Then we'll write some IaC code using Pulumi, a tool for writing IaC using the programming languages we're used to. When we're done, you'll understand enough of the basics to add Pulumi IaC to your projects.
