How Clusters Work in Distributed Systems: A Deep Dive

Clusters are at the heart of distributed systems, enabling scalability, reliability, and fault tolerance. In this video, we explore the two main types of cluster configurations—Leader-Follower and Independent Node Clusters. Learn how clusters distribute workloads, manage failures, and achieve high availability using real-world examples like MySQL, Apache Kafka, and CDNs. Whether you're a software engineer or tech enthusiast, this breakdown will sharpen your understanding of cluster architecture and its importance in modern systems.
