Resilient AWS Architecture: Scenario-Based Practice and Solutions

Building cloud applications that stay online during unexpected failures is a critical skill for any modern cloud professional. Understanding how to architect for high availability, fault tolerance, and disaster recovery on AWS ensures your systems remain secure, performant, and cost-effective. This text-based course guides you from foundational cloud concepts to analyzing and solving complex architectural scenarios. You will learn to evaluate system requirements, identify single points of failure, and apply industry-standard AWS patterns to build robust, resilient cloud infrastructures. What you'll learn: 1. Understand core resiliency concepts, including recovery time objectives (RTO) and recovery point objectives (RPO). 2. Design multi-Availability Zone and multi-region architectures to eliminate single points of failure. 3. Configure auto-scaling and load balancing to handle traffic spikes and maintain performance. 4. Implement modern observability and monitoring strategies to detect and recover from failures automatically. 5. Apply infrastructure-as-code principles to ensure consistent and repeatable environment deployments. 6. Analyze real-world architectural scenarios to select the most cost-effective and secure disaster recovery strategies. The course begins with essential terminology and foundational resilience principles before guiding you through structured, scenario-based written exercises that mimic real-world engineering challenges. This course is designed for beginners, aspiring cloud architects, and developers looking to strengthen their architectural decision-making skills on AWS. No prior cloud design experience is required.
