Scaling Crisis: Your Monolithic Worker Has Hit the Wall
Six critical workloads share one process, one deployment, and one busy flag — and customers are feeling the pain.
Situation
You're the lead engineer on a platform where all background processing runs through a single monolithic worker. Six distinct event-driven workloads share one process with an in-memory busy flag enforcing sequential processing. Customers are experiencing delays, deployments risk everything, and you've discovered a race condition that will become catastrophic if you scale horizontally.
Stakes
- Compliance-critical data processing with strict SLAs
- Data integrity risk from database collection contention
- Business blocked from scaling individual workloads independently
Leadership wants this scaling problem solved. The monolithic worker processes compliance-critical data that cannot go down. What's your migration strategy?
