Building High Availability Clusters on Linux

Uninterrupted service delivery is crucial for any modern application or system. Downtime can lead to significant losses and impact user trust, making high availability a cornerstone of reliable infrastructure. This course will guide you through the principles and practical steps to implement fault-tolerant systems, ensuring your services remain online even in the face of component failures. By the end, you will be able to confidently design and deploy high availability solutions that minimize downtime and protect your data. What you'll learn: * Learn the foundational concepts of high availability, fault tolerance, and clustering. * Understand critical cluster components like quorum, fencing, and resource agents. * Configure shared storage solutions essential for clustered environments. * Implement and manage clustered services for continuous operation. * Apply fundamental Infrastructure-as-Code principles to streamline cluster configuration. * Practice basic monitoring and troubleshooting techniques for cluster health. Starting with core definitions, the course moves through cluster setup, resource configuration, and practical exercises to solidify understanding. This course is designed for beginners in system administration and DevOps who are new to high availability clustering, with no prior experience required. Start building resilient systems today.
