The software simulates failures of instances of services running within Auto Scaling Groups (ASG) by shutting down one or more of the virtual machines. You must be managing your apps with Spinnaker to use Chaos Monkey to terminate instances. SimianArmy - Tools for keeping your cloud operating in top form.
One of the first systems our engineers built in AWS is called the Chaos Monkey. The technology that Netflix shared with the world ( Chaos Monkey and the Simian Army) was seen by many people as the genesis of chaos testing and chaos engineering.
But how revolutionary are these concepts?
The most notable of these tools is the Chaos Monkey (see Related topics for this and other tools), which was developed .
The Freedom and Responsibility culture at. Some engineers at Netflix use this feature to opt out small clusters that are used for testing. Netflix tests its Amazon cloud by randomly taking virtual machines offline. The Chaos Monkey is an excellent tool to test how your infrastructure behaves under unknown failure conditions.
By triggering and dealing with random system failures, you help your product and service harden up and become resilient. This has obvious benefits to your uptime metrics and overall quality of . Simian Army consists of services (Monkeys) in the cloud for generating various kinds of failures, detecting abnormal conditions, and testing our ability to survive them.

More details can be found at this blog. Currently the simians include Chaos Monkey , Janitor . Once configured and deploye it will randomly terminate or otherwise interfere with the operation of your ECinstances and ECS tasks. Latency Monkey induces artificial delays in our . Tests that interact with MySQL. There are some tests that interact with MySQL. The simplest way to run these tests is to install . This page describes the manual steps required to build and deploy.
A great way to contribute to this project would be to use Docker containers to make it easier for other users to get up and running quickly. The unmitigated success of this approach inspired the creation of the Simian Army, a full suite of tools . A tool that randomly disables Netflix production instances to make sure they can survive this common type of failure without any customer impact.
