# Architecture Decision Record A powerful stack for building APIs that is flexible, performant, and easy to reason about. * Cloud: AWS - status quo for QOS (we're not locked into it) * CI/CD: Gitlab - multi-cloud, versatile, FOSS (ENA is already using it) * Deployment: Terraform - declarative, IaC, multi-cloud * Containers: Docker - consistency between environments, rootless in dev * TypeScript: type-safety, anyone with JS experience can contribute (ServiceNow uses JS) * Runtime: [Deno](https://deno.com/) - secure-by-default, URL-based module resolution, dependency locking, built-in toolchain * API Layer: [hono](https://hono.dev/) - portable, fast, simple, automatic OpenAPI w/ [@hono/zod-openapi](https://hono.dev/examples/zod-openapi) * OpenAPI UI: [scalar](https://scalar.com/)/[hono-api-reference](https://github.com/scalar/scalar/blob/main/packages/hono-api-reference/README.md) - offline-first, code generation The strong alternative would be Python with FastAPI, which might be more suitable for smaller projects.
