Feed: AWS Architecture Blog. “Everything fails all the time” Werner Vogels, AWS CTO In 2010, Netflix introduced a tool called “Chaos Monkey”, that was used for introducing faults in a production environment. Chaos Monkey led to the birth of Chaos engineering where teams test their live applications by purposefully injecting faults. Observations are then used to take corrective action and increase resiliency of applications. In this blog, you will learn about the fault injection capabilities available in Amazon Aurora for simulating various database faults. Chaos Experiments Chaos experiments consist of: Understanding the application baseline: The application’s steady-state behavior Designing an experiment: ... Read More
