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 - secure-by-default, URL-based module resolution, dependency locking, built-in toolchain
API Layer: hono - portable, fast, simple, automatic OpenAPI w/ @hono/zod-openapi
OpenAPI UI: scalar/hono-api-reference - offline-first, code generation

The strong alternative would be Python with FastAPI, which might be more suitable for smaller projects.
