Should you use Terraform or Bicep? This is the most common question in Azure DevOps today.
Terraform Wins When…
- Multi-Cloud: You need to deploy to AWS, Azure, and Datadog in the same pipeline.
- State Management: You need complex state manipulation (importing existing resources).
Bicep Wins When…
- Azure Native: You only use Azure. Day 0 support for new features. (Terraform providers often lag by weeks).
- Simplicity: No state file to manage (`terraform.tfstate`). State is Azure itself.
- Integration: Native integration with Azure Policy and Blueprints.
My verdict: If you are 100% Azure, use Bicep. If you are hybrid, Terraform is non-negotiable.
