Deploying multi-audience NestJS with Docker & K8s, horizontally

This post shares real experience splitting a single NestJS codebase into two independent services for production.

Why split the service

Separating web/cms lets each scale to its actual load — public traffic is usually far higher than admin traffic.

Deploying on K8s

Each service gets its own Deployment and HorizontalPodAutoscaler, both pointing at one database through a connection pool.
