![]() ![]() The Simian Army section explores all the additional tools created after Chaos Monkey. We've also included step-by-step technical tutorials for getting started with Chaos Monkey, along with advanced engineering tips and guides for those looking to go beyond the basics. The Chaos Monkey Guide for Engineers is a full how-to of Chaos Monkey, including what it is, its origin story, its pros and cons, its relation to the broader topic of Chaos Engineering, and much more. This guide will cover all the details of these tools in The Simian Army chapter. For example, the Latency Monkey tool introduces artificial delays in RESTful client-server communication, allowing the team at Netflix to simulate service unavailability without actually taking down said service. Inspired by the success of their original Chaos Monkey tool aimed at randomly disabling production instances and services, the engineering team developed additional "simians" built to cause other types of failure and induce abnormal system conditions. In 2011, Netflix announced the evolution of Chaos Monkey with a series of additional tools known as The Simian Army. ![]() By performing the smallest possible experiments you can measure, you're able to "break things on purpose" in order to learn how to build more resilient systems. Chaos Engineering lets you validate what you think will happen with what is actually happening in your systems. By proactively testing how a system responds to failure conditions, you can identify and fix failures before they become public facing outages. Chaos Engineering is a disciplined approach to identifying failures before they become outages. The discipline of experimenting on a distributed system in order to build confidence in the system's capability to withstand turbulent conditions in production.Ĭhaos Monkey helped jumpstart Chaos Engineering as a new engineering practice. Intentionally causing this single failure would suss out any weaknesses in their systems and guide them towards automated solutions that gracefully handle future failures of this sort. Following their migration to the cloud, Netflix's service was newly reliant upon Amazon Web Services and needed a technology that could show them how their system responded when critical components of their production service infrastructure were taken down. Netflix designed Chaos Monkey to test system stability by enforcing failures via the pseudo-random termination of instances and services within Netflix's architecture. This also helped find "stateful" services, which relied on host resources (such as a local cache and database), as opposed to stateless services, which store such things on a remote host. By pseudo-randomly rebooting their own hosts, they could suss out any weaknesses and validate that their automated remediation worked correctly. In this new environment, hosts could be terminated and replaced at any time, which meant their services needed to prepare for this constraint. ![]() In 2010, Netflix decided to move their systems to the cloud. ![]()
