Pattern 75 / RESILIENCE

Load Shedding

Use this when Protecting core service during overload.

Pressure
Protecting core service during overload
Mechanism
Reject or degrade lower-priority requests once capacity guardrails are crossed
Toll
User-visible errors are intentional; prioritization must be defensible
Architecture plate75
Diagram for Load Shedding
Executive brief

Load Shedding fits when Protecting core service during overload. Mechanism: Reject or degrade lower-priority requests once capacity guardrails are crossed. Use it for Traffic spikes, dependency failures, incident containment. The toll: User-visible errors are intentional; prioritization must be defensible.

Use when

Traffic spikes, dependency failures, incident containment.

Example

Use load shedding when traffic spikes, dependency failures, incident containment..

Review framing

Describe the pressure first, then the mechanism, then the cost. That keeps the design grounded.
