Enterprise Resiliency: High-Availability and Disaster Recovery

In today's digital landscape, system downtime can cost organizations millions and damage customer trust. Building resilient enterprise systems requires proactive planning, robust design patterns, and continuous testing rather than reactive troubleshooting. This text-based course prepares you to analyze, design, and maintain high-availability infrastructures. You will transition from understanding basic redundancy to implementing modern disaster recovery strategies that protect critical applications and data during unexpected failures. What you'll learn: Understand foundational enterprise resiliency concepts, key terminology, and recovery objectives; Design high-availability architectures across hardware, operating systems, middleware, and applications; Plan effective disaster recovery strategies to restore operations without data loss during major site outages; Implement modern observability and monitoring practices to detect and mitigate potential failures early; Apply zero-trust principles and secure failover patterns to maintain system integrity; Practice formulating resiliency plans through structured scenarios and tabletop exercises. The course begins with essential definitions and core architecture patterns before moving into practical strategies for data replication, site recovery, and continuous monitoring. You will progress from theoretical concepts to structured planning methodologies through clear written explanations and architectural scenarios. This course is designed for beginner IT managers, system administrators, junior architects, and programmers who want to build a strong foundation in system reliability. No prior experience in disaster recovery planning is required. Start building systems that withstand adversity and ensure business continuity.
