Disaster Recovery and High Availability: RTO and RPO in the Cloud

When system downtime can cost thousands of dollars per minute, understanding how to keep cloud applications running is a critical skill for any IT professional. This text-based course guides you through the fundamental principles of Disaster Recovery (DR) and High Availability (HA). You will learn how to define key metrics like Recovery Time Objective (RTO) and Recovery Point Objective (RPO), and understand how to apply these concepts to design robust cloud architectures that minimize data loss and downtime. What you'll learn: - Learn the core differences between High Availability, Fault Tolerance, and Disaster Recovery. - Define and calculate Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for various business scenarios. - Explore modern cloud disaster recovery strategies, from simple backup-and-restore to active-active multi-region deployments. - Understand how continuous data protection and automated failover mechanisms minimize data loss. - Analyze real-world trade-offs between cost, complexity, and recovery speed when planning cloud infrastructure. You will start by mastering foundational terminology and disaster definitions, then progress to calculating recovery objectives, and finally explore practical architectural patterns used in modern cloud environments. This course is designed for beginners, including aspiring cloud engineers, system administrators, and IT managers, with no prior disaster recovery experience required.
