ConcurrencyProcessModel [principle] v1.0.0

Scale by adding processes, not by making one process bigger. Different work types map to different process types — web for HTTP, worker for background jobs, clock for scheduled tasks. Each type scales independently. The unix process is the unit of scale.

Scale out, not up. Each process type is a horizontally-scalable share-nothing unit.

Applies To

• Procfile-style declaration of process types: web, worker, scheduler.
• Each type scales by count: 'web=10, worker=4, scheduler=1'.
• Internal threading is fine inside a process, but never the only scaling lever.
