Disaster Recovery Testing at Booking.com

Wednesday, 26 October, 2022 - 14:0014:40 CEST

Yoann Fouquet, Booking.com, and Paola Martinucci, Mollie.com


Large disasters can be due to equipment failures, user errors, natural disasters, malware and other unexpected events. At Booking.com, we have established a program to test the impact of these disasters and the recovery mechanism that we have in place. Those tests started years ago with simple region evacuation in normal conditions, and later expanded to injection of latency at the network level, packet dropping, cut of inter-datacenter connection, cut of power feed or even region-wide shutdown.

In this talk, we are not giving a master class on disaster recovery testing, but rather sharing 4 years of knowledge acquired during this program: the improvement of the reliability of our platform, the organisational impact, the automation created for or after the tests, … but also a few things that actually went wrong. We will finally discuss how this was applied to mitigate real incidents that have happened since the start of the project.
