Computer Cluster

Introduction

Computer clusters play a crucial role in modern computing, enabling organizations to harness the combined processing power of multiple interconnected computers. Whether it's high-performance computing, high-availability systems, or load-balancing clusters, understanding how to effectively leverage their capabilities is essential in today's technology-driven landscape.

Throughout this course, we will explore the key concepts, architectures, and software involved in building computer clusters. You will gain hands-on experience through practical exercises, learning how to optimize performance, troubleshoot common issues, and ensure fault tolerance and high availability.
