Review your API for denial-of-service risks by evaluating request handling, concurrency ceilings, timeout policies, and rate limiting on exposed paths. Check that resource bounds and early rejection controls are in place to prevent saturation and slowdowns.

Graceful degradation prevents application outages by ensuring systems shed load or reduce functionality under saturation. It involves assessing backpressure, retries, and failover behavior so that attacker-controlled requests or brittle dependencies do not force resource exhaustion.

Check rate limiting and timeout controls by reviewing request sizing, concurrency ceilings, and timeout policies across exposed paths. Verify that early rejection mechanisms and saturation controls are actively configured rather than relying on unverified assumptions.

Yes, you can assess background workers, file processing, session handling, and distributed services for denial-of-service exposure. The review checks resource bounds, failover behavior, and concurrency controls to identify slowdowns or outages from expensive processing.

The best way to identify missing concurrency ceilings is through evidence-based assessment of request handling and saturation controls. Review failover behavior, backpressure, and early rejection mechanisms to find weak rate controls before an outage occurs.

Your application slows down under heavy loads if basic rate limits lack proper concurrency ceilings, timeout policies, and graceful degradation. Brittle dependencies and missing early rejection controls allow expensive processing to exhaust resources and cause saturation.
