Circuit Breaker
Prevent cascading failures by stopping calls to failing services
Intent & Description
The Circuit Breaker pattern prevents cascading failures by stopping calls to failing services after a threshold of failures is reached. The circuit transitions between closed, open, and half-open states. In GKE environments, this can be implemented using service mesh features or custom libraries.
Real-world Use Case
Use when connecting to services that may experience failures or when you need to prevent cascading failures in distributed systems.
