Ranked picks for containers & infrastructure. No "it depends."

Terraform
Nice PickWhy we picked it
Terraform is the most mature infrastructure-as-code tool, but its HCL language and state management complexity make it slower to work with than Pulumi's general-purpose languages. It has the largest provider ecosystem, but that breadth comes at the cost of a clunky workflow and frequent state conflicts. For teams that need maximum provider coverage and can stomach the overhead, it works; for anyone else, Pulumi or CDKTF is a better bet.
→ Use it when you need the widest possible provider support and your team is already invested in HCL, accepting slower iteration and manual state handling.
Pros
Cons
Why we picked it
Kubernetes is the de facto standard for container orchestration, but its complexity is a real cost. It beats Docker Swarm in scalability and ecosystem breadth, but for most teams, the operational overhead isn't justified. If you don't need multi-cloud portability or massive scale, you're paying for complexity you won't use.
→ Use it when you're running a distributed system at scale across multiple environments and need the flexibility of a unified control plane, not when you just want to run a few containers on a single host.
Pros
Cons
Why we picked it
Docker is the de facto standard for containerization because it made containers usable for developers. Its ecosystem — Docker Compose, Docker Hub, and the sheer volume of community images — is unmatched. Podman can run rootless and Buildah builds without a daemon, but neither has the same breadth of tooling or mindshare. You use Docker because everyone else does, and that network effect is the feature.
→ Use it when you need to package, ship, and run applications consistently across environments and want the most supported, documented, and integrated container platform available.
Pros
Cons
Infrastructure as Code for developers who'd rather write real code than YAML incantations.
Pros
- +Uses general-purpose languages like TypeScript and Python for better code reuse and testing
- +Supports multiple cloud providers (AWS, Azure, Google Cloud, Kubernetes) in a unified workflow
- +Integrates seamlessly with existing development tools and CI/CD pipelines
Cons
- -Can be overkill for simple infrastructure, adding unnecessary complexity
- -Steeper learning curve compared to simpler IaC tools like Terraform
