Chaos engineering tools enable the use of experimental and potentially destructive failure testing or fault injection testing to uncover vulnerabilities and weaknesses within a complex system. These tools enable I&O and software engineering teams — as well as security engineers and site reliability engineers (SREs) — to systematically plan, document, execute and analyze attacks on components and systems, both before and after deployment to production. Site reliability engineers, software engineers and security experts use these tools to proactively increase the resilience of infrastructure, applications and processes. Chaos engineering tools uncover weaknesses within complex systems via injection of potentially destructive failures or faults by: - Planning attacks including discovering system dependencies - Documenting plans for repeatability - Offering a rich set of attack libraries with support for public clouds and cloud-native architectures - Executing experimental attacks on system resources, states, binaries and data - Documenting the results
