Pattern 77 / RESILIENCE

Fail-Fast

Use this when Avoiding wasted work when success is unlikely.

Pressure
Avoiding wasted work when success is unlikely
Mechanism
Return quickly when preconditions, capacity, or dependencies are unavailable
Toll
Can be too aggressive without good health signals

Executive brief

Fail-Fast fits when Avoiding wasted work when success is unlikely. Mechanism: Return quickly when preconditions, capacity, or dependencies are unavailable. Use it for APIs, overloaded services, downstream outage handling. The toll: Can be too aggressive without good health signals.

Use when

Apis, overloaded services, downstream outage handling.

Example

Use fail-fast when apis, overloaded services, downstream outage handling..

Review framing

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

Same pressure family
