Can we inject failure scenarios into deployed systems to reduce platform risk? During this talk, demonstrations of the Simian Army, Chaos Lemur and Locust.io tools will be presented. We will go beyond reliability, stability and availability to help your platform operations team build a continuous process improvement program which will prepare your production systems for the unexpected. 92% of catastrophic system failures were the result of incorrect handling of nonfatal errors. It is simply not possible to fully reproduce the entire architecture and run an end to end test. Don't trust claims systems make about themselves & their dependencies. Verify by breaking.
