Synchronous communication - circuit breaker and fallback

This technical article explains the circuit breaker pattern for synchronous communication in software systems, a design pattern that prevents cascading failures. It draws an analogy to electrical circuit breakers, describes the open, closed, and half-open states, and discusses the importance of fallback values. The article then provides a practical, code-based examination of implementing circuit breakers using the Hystrix and Resilience4j libraries in a controlled test scenario.
