Core strategies for detecting, classifying and handling errors in software systems.
Error handling defines strategies and mechanisms to detect, classify and respond to faults in software systems. It covers input validation, consistent error responses, fallback paths and recovery tactics to ensure resilient runtime behavior. Effective error handling reduces downtime, improves debugging and supports clear user communication.
Proportion of failed requests per time window.
Average time to recover after an error.
Frequency of alerts requiring immediate action.
A REST API returns standardized problem JSON for machine-readable error handling.
On partial failure, compensating steps are executed to restore consistency.
Protects dependent services from further requests after repeated failures.
Define and prioritize an error taxonomy.
Establish standardized error formats and codes.
Implement logging and tracing conventions.
Introduce and test fallbacks, retries and circuit breakers.
