Why Heartbeat Mechanisms Are Critical for Distributed System Reliability

This article explains how periodic heartbeat messages enable distributed systems to detect node failures, choose appropriate intervals and timeouts, compare push and pull models, employ advanced detection algorithms like phi and gossip, and apply these concepts in real-world platforms such as Kubernetes, Cassandra, and etcd.
