Quick Answer
Bulkhead pattern allocates separate thread pools (or connection pools) for different downstream dependencies. If calls to service B are slow and fill up their thread pool, calls to service C (in a different pool) are unaffected. Without bulkheads, a slow dependency exhausts the shared thread pool and the entire service becomes unresponsive to all requests.
Answer
Bulkhead isolates resources into partitions. Prevents one service failure from affecting others. Improves system fault isolation and stability.
