Designing Resilient Systems: Architecture and Fault Tolerance

Modern software systems must remain operational even when underlying infrastructure fails. Understanding how to architect for resilience is a critical skill for any aspiring developer or system designer. This course guides you through the fundamental principles of designing robust, self-healing systems. You will transition from writing simple applications to conceptualizing distributed architectures that gracefully handle network partitions, hardware failures, and unexpected traffic spikes. What you'll learn: Understand foundational resilience concepts, including high availability, fault tolerance, and disaster recovery; Design system architectures using patterns like circuit breakers, retries, rate limiting, and bulkheads; Implement modern observability practices using metrics, logs, and traces to detect failures early; Apply infrastructure-as-code principles to deploy consistent and repeatable environments; Explore chaos engineering basics to proactively test system resilience under stress; Configure redundancy and failover strategies for databases and application services. The course starts with essential terminology and core architectural concepts before moving into practical strategy formulation, distributed system trade-offs, and modern monitoring techniques through clear written explanations and architectural scenarios. This course is designed for beginner developers, system administrators, and aspiring architects who want to build reliable software. No prior system design experience is required.
