Use circuit breakers and bulkheads to isolate failing components. This approach ensures fault isolation and graceful degradation, maintaining high availability during partial outages and preventing system-wide meltdowns.

Apply exponential backoff with jitter. This traffic management strategy randomizes retry intervals, preventing synchronized client retries from overwhelming dependencies during traffic spikes or slow responses.

You need a circuit breaker when a microservice dependency becomes slow or unresponsive. It monitors failure rates and trips to stop requests, enabling graceful degradation by returning cached responses instead of system errors.

Combine failure containment patterns like bulkheads and circuit breakers with load shedding. Validate design choices against stress-test scenarios including retry storms and single points of failure to ensure self-healing during partial outages.

Rate limiting improves system availability by controlling traffic spikes. Combined with load shedding, it prevents meltdowns by restricting incoming requests, ensuring services remain responsive when dependencies fail or experience sudden surges.
