How To Build Resilience With Linux High Availability Clustering
Linux Journal, Thursday, April 11th, 2024
In the age of digital transformation, the uptime and continuous availability of systems are paramount for businesses across all sectors. High Availability (HA) clustering has emerged as a critical strategy for ensuring that services remain accessible, even in the face of hardware or software failures.
Linux, with its robustness and flexibility, serves as an ideal platform for deploying HA solutions. This article delves into the concept of Linux High Availability Clustering, exploring its mechanisms, technologies, and the vital role it plays in building resilient and fault-tolerant systems.
Concept of Clustering
At its core, a cluster is a group of interconnected computers that work together as a single system to provide higher levels of availability, reliability, and scalability. Unlike standalone servers, clusters are designed to manage failures seamlessly and ensure that services are not disrupted. Clustering can be categorized primarily into two types: Active-Active and Active-Passive.
