principle-resiliency

What problem does it solve?

Resiliency guidance helps prevent systems from failing completely when dependencies, networks, or components degrade, by designing for partial failure and controlled degradation instead of cascading outages.

Core Features & Use Cases

• Failure domain clarity: Identify what fails together to avoid “unnamed blast radii” and to reason about cascading failure paths.
• Blast-radius control with bulkheads: Isolate resource pools per dependency (connection pools, semaphores, thread pools, queues) to prevent one slow dependency from starving others.
• Correct failure handling and fallback strategy: Choose fail-fast vs fail-soft appropriately, design graceful degradation modes, and ensure health checks (liveness vs readiness) don’t create restart storms or probe storms.

Quick Start

Ask for a resiliency review of your service design focused on failure domains, bulkheads, fail-fast versus fail-soft decisions, graceful degradation options, and health-check behavior under upstream outages.
