   Who Is Pulumi Best For?

   Pulumi is a strong fit for DevOps and platform engineering teams that want to manage cloud infrastructure in the same programming languages they use to build applications.

   Why I Picked Pulumi

   I picked Pulumi as one of the best because it's the only IaC platform where your infrastructure is genuinely written in TypeScript, Python, Go, or Java—not a templating language bolted on top. What really sets it apart is Neo, an AI agent that handles multi-step infrastructure tasks end to end, generates code, diagnoses deployment failures in plain English, and even posts AI-driven code reviews directly on your PRs. Pair that with review stacks that spin up a real cloud environment for every pull request and tear it down on merge, and you get a tight, code-native DevOps workflow that Terraform simply can't match.

   Pulumi Key Features

   • Policy as code enforcement: Write compliance policies in TypeScript or Python and enforce them as advisory or mandatory gates that block non-compliant deployments.
   • Drift detection and remediation: Continuously compares live cloud resources against your code and can automatically fix any configuration drift on a schedule.
   • Pulumi ESC secrets management: Centrally manage, version, and rotate secrets and environment configs across stacks, with dynamic credentials and approval workflows.
