OVH’s Backup Service Didn’t Work (Restore it All Podcast #107)

This week we discuss further lessons from the OVH fire, which starts with an admission by the CEO that some customers who paid for the backup service lost their backups in the fire. It then morphs into a discussion about designing resilient systems, starting with the concept of designing for failure. You have to protect against both physical and logical damage to your apps and data. We talk about using both cloud-native apps that have resiliency built in, vs having to add resiliency to your own app. Most importantly, know how your app/data is protected, and don’t tolerate wishy-washy terminology in your service agreements. Above all, test, test, test!

    I was listening to your podcast this morning and the two of you got into multi-region applications and multi-region databases. You were headed down a line of discussion related to AZ and region failures and how those components need to respond.
    About six months ago I started working for Cockroach Labs, which has created a distributed, multi-region, ACID compliant, serializable isolation (guaranteed consistency), database that can handle region failures. As you can imagine, it is not a trivial computational problem… doubly so when you’re wrapping this thing around the globe [read: we’re fighting the speed of light]. If you’d like to have someone on the show to get into some of the concepts for type of topic, I’d be more than willing.

    PS – I have a face for radio [and a voice for silent movies].
