Controlled Chaos

Major outages in major public cloud providers such as Azure and AWS are rare, but they do happen. Today OVH had a major incident: “OVH datacenter burns down knocking major sites offline” and they’re not the only ones to experience these issues, for example Amazon had a major outage in November and Microsoft had one in September.

This prompted me to write up an article on Akimbo’s recent work building resilience into our platform, so today I’m going to talk a little bit about a couple of the features of AWS that allow for significant resilience and I’m going to do that by running you through my recent experiments on our platform which can be roughly summarised as “Turning things off to see what breaks.”
