Answer
The bulkhead pattern isolates service resources, such as thread pools or memory, to prevent one failing process from impacting others. It improves resilience and fault isolation.
Quick Answer
Bulkhead pattern isolates failures by giving each service or feature its own resource pool - separate thread pools, connection pools, or instances. If one service gets overwhelmed (or leaks resources), it only consumes its own pool and doesn't starve other services. Named after ship bulkheads that keep one flooded compartment from sinking the whole ship.
