Introduction to Chaos Engineering and System Resilience

Modern distributed systems are highly complex, making unexpected failures inevitable. To build truly resilient software, you must learn to anticipate these failures rather than simply reacting to them when they occur in production. This text-based course guides you through the foundational principles of chaos engineering, teaching you how to systematically inject controlled faults to uncover hidden vulnerabilities before they impact your users. You will start with the essential terminology, core concepts, and the history of resilience engineering before moving into practical methodologies. What you'll learn: Understand the core principles of chaos engineering and the hypothesis-driven experiment lifecycle; Plan and execute controlled experiments targeting network latency, dependency failures, and resource exhaustion; Define steady-state metrics and establish reliable system baselines to measure deviation; Apply modern observability patterns to monitor system health and safely trigger automated rollbacks; Implement chaos engineering practices in cloud-native environments using modern tooling. This comprehensive written guide takes you step-by-step from foundational resilience theory to planning your first real-world failure injection experiments. This course is designed for software developers, system administrators, and site reliability engineering beginners who want to build more robust applications with no prior chaos testing experience required.
