Gremlin has introduced Scenarios to enhance its Chaos Engineering platform, allowing users to simulate complex real-world outages by linking multiple failure modes, which increases the blast radius and magnitude over time. Scenarios are designed to make planning and executing reliability tests easier, and they include pre-built Recommended Scenarios based on past significant outages, such as the 2017 AWS S3 incident, to help users validate their systems’ resilience. Users can create, document, and observe the effects of these Scenarios, hypothesizing expected outcomes and noting actual observations to improve system reliability. Additionally, Scenarios can be scheduled to run regularly, ensuring ongoing assessment and mitigation of potential failures. Gremlin offers these features to all users through its platform, encouraging teams to test and enhance application reliability continuously.
