A slow dependency can occupy all outbound connections. A noisy tenant can fill every worker slot. A background job can take the same semaphore permits needed by interactive requests.</p> <p>Bulkhead isolation limits that coupling. Instead of letting unrelated work compete for one undifferentiated pool, the system partitions selected resources and gives each class of work a bounded share. Saturation then has a smaller blast radius.</p>
