What is a Chaos Monkey?
Chaos Monkey is a software tool that was developed by Netflix engineers to test the resiliency and recoverability of their Amazon Web Services (AWS). The software simulates failures of instances of services running within Auto Scaling Groups (ASG) by shutting down one or more of the virtual machines.
Why is chaos monkey important for Netflix?
Netflix designed Chaos Monkey to test system stability by enforcing failures via the pseudo-random termination of instances and services within Netflix’s architecture.
How do you run a Chaos Monkey?
Chaos Monkey does not run as a service. Instead, you set up a cron job that calls Chaos Monkey once a weekday to create a schedule of terminations. When Chaos Monkey creates a schedule, it creates another cron job to schedule terminations during the working hours of the day.
Why do we practice chaos engineering Gremlin?
The goal of chaos engineering is to identify weakness in a system through controlled experiments that introduce random and unpredictable behavior. A main benefit of chaos engineering is that organizations can use it to identify vulnerabilities before a hacker does or before a system failure.
