If you're getting into infrastructure as code, you hit the same fork in the road I did: Terraform or Pulumi? Both let you define cloud infrastructure in files instead of clicking around a console. Both are widely used. So which one do you actually learn first?
Short answer: learn Terraform first, then try Pulumi once you understand the core ideas. I'll explain why, and when the opposite makes sense.
What they actually are
Terraform came out in 2014 and became the default way teams manage cloud infrastructure. You write config in a language called HCL (HashiCorp Configuration Language), run a plan, and apply it. It's declarative, which means you describe the end state and Terraform figures out the steps to get there.
Pulumi arrived in 2018 with a different bet. Instead of a custom language, you write infrastructure in a language you probably already know: Python, TypeScript, Go, C#, or Java. Six languages in total. Same goal, real code.
