Gremlin
Gremlin is a chaos engineering platform that helps developers and operations teams proactively test and improve the resilience of their systems by safely injecting failures into production environments. It simulates real-world incidents like server crashes, network latency, or resource exhaustion to identify weaknesses before they cause outages. By automating controlled experiments, Gremlin enables teams to build confidence in their systems' ability to withstand unexpected disruptions.
Developers should learn and use Gremlin when building or maintaining distributed systems, microservices architectures, or cloud-native applications where reliability is critical, such as in e-commerce, finance, or healthcare. It is particularly valuable for implementing chaos engineering practices to validate fault tolerance, reduce mean time to recovery (MTTR), and meet service-level objectives (SLOs) by uncovering hidden dependencies and single points of failure.
