The point about building Kubernetes readiness into the codebase from the start rather than treating it as a panic migration project is exactly right. What I would add is that this same discipline applies to authentication and security architecture. Most teams bolt security on after the fact the same way they bolt on Kubernetes, and both decisions cost them later. Building a production grade authentication system with NestJS recently reinforced this for me. JWT token management, role based access control, brute force protection, these are not features you add when you need them. They are architectural decisions you make from day one. The teams that get this right are the ones that treat security the same way this post treats infrastructure, as a background condition of the codebase, not an afterthought.
