Building Resilient Systems: Fault Tolerance and Chaos Engineering
Building Resilient Systems: Fault Tolerance and Chaos Engineering Resilient systems stay available and correct when things fail. Fault tolerance means your service keeps working even if parts fail. Chaos engineering is a practical method: you simulate failures in a controlled way to learn how the system behaves and to tighten the gaps. The goal is to reduce risk before a real outage hits. Think about fault tolerance in three layers. First, design for redundancy so a single point of failure does not bring everything down. Second, keep systems operating with graceful degradation, offering limited functionality instead of a full stop. Third, automate recovery with timeouts, retries, and smart routing. These patterns help you survive unexpected delays, outages, and traffic spikes without surprising users. ...
