The Spinnaker project is looking more appealing with every outage. Outage detected in X provider in Y region? Deploy infrastructure to Z provider in Y region.

Or just deploy to us-west-2 (or maybe us-east-2) in the first place and then enjoy not having to do anything every time there’s an outage in us-east-1, which is where pretty much all the AWS outages are.

And if there is an issue for some reason failing over to another AWS region is a lot easier than having to fail over to another cloud provider. Outside of a very small number of cases building for multi-cloud is a lot of unnecessary work.

This outage is only affecting a single availability zone, so taking on the complexity of multiple cloud providers would not be necessary to be resilient against it. AWS best practices would already have covered you.

Where does it say it's a single AZ?

Every "more" drawer/dropdown

AWS best practices involve using AWS for everything, which is not actually a best practice.

Deploying a database with 5 TB on disk and 50k data-modifying transactions per second to multiple providers isn't exactly trivial.

Who cares about stateless, that's a solved problem.

The volume and storage numbers you quoted call for breaking up a monolithic system. We have a similar overall volume of transactions and storage needs to yours but we reside in all US regions, tens of AZs. If one AZ went down, a small fraction of customers would be affected. True, we have increased our exposure to an outage happening somewhere but we improved overall business continuity. Simply put, dealing with 5% of pissed customers is easier than 50% or all of them calling you at once.

From their Multi-Cloud section on their homepage:

> Deploy across multiple cloud providers including AWS EC2, Kubernetes

Kubernetes... where?

Probably self hosted.

Lol, or just architect your applications to be highly available and fault-tolerant to regional failures if that's your business requirement.
