Our team is moving toward a full DevOps model and we need to automate our AWS environment. Should we stick with the industry-standard HCL in Terraform, or is there a significant advantage to using general-purpose languages like Python or TypeScript in Pulumi?

Terraform is currently the gold standard in DevOps because its declarative nature makes it very easy to understand the "desired state" of your infrastructure. HCL is purpose-built for infra, meaning it prevents you from writing overly complex logic that can make debugging a nightmare. Pulumi is powerful if your team consists entirely of software developers who want to stay in Python, but it can lead to "clever" code that is hard for operations folks to manage. For most DevOps transitions, Terraform’s massive provider ecosystem and mature state management make it the safer bet.
If we choose Terraform, how do you suggest managing the state file in a multi-region deployment to prevent state locking issues or data corruption?
Don't forget about Terragrunt! It’s a great wrapper for Terraform that helps keep your code DRY (Don't Repeat Yourself) when managing multiple environments.
Great addition, Janet. Keeping IaC code DRY is one of the biggest challenges as DevOps teams scale their infrastructure across staging and production.
For AWS, we always use S3 for remote state storage combined with DynamoDB for state locking, Philip. This is a fundamental DevOps pattern that prevents two developers from applying changes simultaneously. It ensures consistency and provides an audit trail of every infrastructure change made via the CI/CD pipeline.
