Episode 70 — Clustering Concepts — Active-Active, Failover, and Heartbeat Protocols

Certified - CompTIA Server+ Audio Course

This episode explains clustering concepts used to enhance server availability and load distribution. We define active-active clusters, where multiple nodes share workloads simultaneously, and active-passive configurations, where standby nodes take over during a failure. The heartbeat protocol is discussed as a critical mechanism for monitoring cluster health and initiating failover when necessary.

We then connect these concepts to both exam and operational contexts, such as designing a high-availability database cluster or configuring failover for critical application services. Troubleshooting considerations include verifying heartbeat connectivity, ensuring synchronized configurations across nodes, and testing failover procedures. Mastery of clustering concepts enables candidates to design resilient systems that meet uptime requirements and minimize service disruption.
