Resilience in API design is essential to build applications that provide consistent and reliable services. This post explores strategies to achieve that.

Designing with Redundancy

Incorporating fallback mechanisms and multiple data sources can help APIs remain functional during outages.

Retries and circuit breakers protect services from cascading failures and improve user experience.

Rate Limiting and Throttling

Controlling traffic helps prevent server overload and maintains response times.

Configurable thresholds allow balancing between user needs and system capacity.

Data Validation and Security

Input validation prevents malformed data from causing errors or security breaches.

Authentication and authorization are foundational to protecting API endpoints.

Monitoring and Alerting

Tracking usage and error rates enables rapid problem detection and response.

Automated alerts ensure teams are notified of issues before users are impacted.
