Designing High Availability and Disaster Recovery Strategies

In today's digital landscape, system downtime can cost organizations significant revenue and damage customer trust. Understanding how to architect systems that remain operational during hardware failures, network outages, or natural disasters is a vital skill for any IT professional. This text-based course guides you through the foundational concepts of High Availability (HA) and Disaster Recovery (DR). You will learn how to evaluate business requirements, define key recovery metrics, and design redundant systems that keep applications running smoothly under unexpected conditions. What you'll learn: Understand the core principles of high availability, fault tolerance, and disaster recovery; Define critical business metrics including Recovery Time Objective (RTO) and Recovery Point Objective (RPO); Compare active-active and active-passive failover strategies for applications and databases; Design multi-region and multi-zone deployment architectures to eliminate single points of failure; Implement robust backup strategies and data replication methods across cloud and hybrid environments; Explore modern resilience practices like automated recovery testing and chaos engineering basics. You will start by mastering essential terminology and foundational concepts before exploring practical architectural patterns, backup strategies, and recovery scenarios. The course concludes with best practices for testing your recovery plans to ensure they work when you need them most. This course is designed for beginner systems administrators, cloud architects, IT managers, and developers who want to learn resilience engineering from scratch, with no prior infrastructure design experience required.
