The original system was a simple MongoDB-backed queue embedded in a monolithic control plane, which became a bottleneck as teams wanted service-oriented ownership. Teams were independently building workflow orchestration layers on top of the primitive queue, creating inconsistency and debugging challenges. After a build-vs-buy analysis, the team chose Temporal for its native workflow orchestration, observability tools (web UI, CLI, event histories), and ability to support independent service teams. Key improvements include better on-call experience through detailed workflow event histories and reduced blame-shifting between platform and owning teams. ## Full article daily.dev links to this article rather than hosting it.
