Discover all the essential tools to construct dependable software with confidence through Chaos Engineering. Take advantage of Gremlin's extensive range of failure scenarios to conduct experiments throughout your entire infrastructure, whether it's bare metal, cloud platforms, containerized setups, Kubernetes, applications, or serverless architectures. You can manipulate resources by throttling CPU, memory, I/O, and disk usage, reboot hosts, terminate processes, and even simulate time travel. Additionally, you can introduce network latency, create blackholes for traffic, drop packets, and simulate DNS failures. Ensure your code is resilient by testing for potential failures and delays in serverless functions. Furthermore, you have the ability to limit the effects of these experiments to specific users, devices, or a certain percentage of traffic, enabling precise assessments of your system's robustness. This approach allows for a thorough understanding of how your software reacts under various stress conditions.
