Downtime Monkey: Build Resilient Applications with Proactive Chaos Engineering
Downtime Monkey is a Chaos Engineering tool that helps developers build resilient applications. It randomly simulates failures like network issues, CPU hogs, file blockers, etc. to proactively test applications for failure conditions.
What is Downtime Monkey?
Downtime Monkey is an open-source Chaos Engineering tool created by Netflix. It is designed to randomly introduce failures like latency, network issues, full system crashes, etc. into production environments.
The main goal of Downtime Monkey is to help developers build resilience into their applications by proactively testing failure scenarios. By injecting faults like high CPU usage, saturated threads, etc. it reveals weaknesses in code and architecture before they affect end users.
Some key features of Downtime Monkey include:
- Ability to induce latency, exception errors, resource hogs, and terminations
- Fine-grained controls over timing, targeting, and blast radius of failures
- Easy integration with infrastructure through custom listeners and actions
- Detailed logging and metrics on failure impact
Overall, Downtime Monkey helps reinforce fault-tolerant systems by ensuring applications can survive real world instability, outliers, and traffic spikes. Its chaos experiments provide deeper confidence in production operations.
