Evolving architecture with DDD and hypermedia -
summary
NRK TV moves from a monolith to bounded contexts using an API gateway (Varnish, nginx) and the Strangler pattern, adding HAL links so clients navigate between catalog, playback and personalization. The system serves half a million users and shifts to plain HTTP caching, independent deploys, and a new playback service plus TV show pages. Personalization runs on Microsoft Orleans, links are retrofitted to legacy endpoints, and the approach reduces coordinated client updates while preserving multiple ways to reach the same goal.
