Explore the evolution of software systems and the challenges of maintaining availability and reliability in complex distributed architectures. Dive deep into the concepts of availability, reliability, and large-scale architectures, and discover how chaos engineering can help identify failures before they become outages. Learn about various strategies for building resilient systems, including auto-scaling, infrastructure as code, immutable infrastructure, and database federation. Understand the importance of designing experiments, implementing service degradation and fallbacks, and quantifying results in chaos engineering. Gain insights into the CAP theorem, eventual consistency, and other key concepts for building robust, fault-tolerant systems. Discover how to apply chaos engineering principles to improve system resilience and prevent failures in large-scale distributed environments.
