🚀 Introduction: Why Circuit Breaker Matters in Microservices?
In microservices architecture, failures in one service can impact multiple services. Common issues include:
✔ Network failures
✔ Service timeouts
✔ Slow response times
Without proper handling, these failures can lead to:
❌ Increased latency
❌ System-wide slowdowns
❌ Cascading failures across microservices
✅ Solution: The Circuit Breaker Pattern
The Circuit Breaker Pattern helps by:
1️⃣ Detecting service failures
2️⃣ Preventing unnecessary calls to…
