This methodology was called chaos testing. Your team needs an effective way to consistently test and monitor your system to ensure point number one is true (Netflix created chaos monkeys to help handle this-more on that later).

Never be 100% confident that number one is true.

A single point of failure refers to the possibility that one error or failure could lead to hundreds of hours of unplanned downtime.

No system should ever have a single point of failure.

At the time, the team at Netflix quickly realized their existing infrastructure would not allow for the scalability that they’d eventually need, so they made the intimidating decision to migrate everything to Amazon’s cloud-based AWS in a monolith-to-microservice transition.ĭuring this time, Netflix established two principles learned from the process of moving over their entire infrastructure while minimizing the impact to its millions of users: In 2010, development and operations teams at Netflix started the process of moving their entire infrastructure over to AWS (Amazon Web Services).
