In this article, we will explore one of the most common and useful resilience patterns in distributed systems: the circuit breaker. The circuit breaker is a design pattern that prevents cascading failures and improves the overall availability and performance of a system.
What Is a Circuit Breaker?
A circuit breaker is a component that monitors the health of a dependency, such as a remote service, an external API, or a database. A dependency can become unhealthy or unavailable for various reasons, such as network failures, high latency, timeouts, errors, or overload. When a dependency is unhealthy, it can cause failures in the components that depend on it, leading to a domino effect that can bring down the whole system.
