In the cloud-native era, Infrastructure as Code (IaC; read more about it in this blog here) has become the de-facto standard for managing cloud infrastructure, and more.

While Terraform has been around for almost a decade, and it had been the one-and-only cloud-agnostic option for a couple of years before competitors emerged, now the landscape is a whole lot more diverse: we’ve got AWS CDK, CDK for Terraform, and there is a relatively new kid on the block: Pulumi.

Having more choices, however, doesn’t necessarily mean they’ll make our lives easier because the decision-making process can be daunting: we have to spend days, if not weeks, investigating all the options before well-informed decisions. In the fast-paced cloud-native/DevOps era, though, not everyone has the luxury to do just that.

Worry no more: in this blog, we will do a deep dive into Pulumi V.S. Terraform (and slightly touch the mechanism of AWS CDK/CDK for Terraform, for that matter). A comparison chart, a decision tree, some tips, and even an FAQ will be included (TL;DR: jump to the last two sections) to further help you choose the right tool for the job.

Without further adieu, let’s get started now.
