To move as fast as they can at scale while protecting mission-critical data, more and more organizations are investing in private 5G networks, also known as private cellular networks or just “private 5G” (not to be confused with virtual private networks, which are something totally different). What is a private 5G network?

The circuit breaker is a design pattern that prevents cascading failures and improves the overall availability and performance of a system. A dependency can become unhealthy or unavailable for various reasons, such as network failures, high latency, timeouts, errors, or overload. What Is a Circuit Breaker?
