Since I'm 5+ years out from my NDA around this stuff, I'll give some high level details here.
Snapchat heavily used Google AppEngine to scale. This was basically a magical Java runtime that would 'hot path split' the monolithic service into lambda-like worker pools. Pretty crazy, but it worked well.
Snapchat leaned very heavily on this though and basically let Google build the tech that allowed them to scale up instead of dealing with that problem internally. At one point, Snap was >70% of all GCP usage. And this was almost all concentrated on ONE Java service. Nuts stuff.
Anyway, eventually Google was no longer happy with supporting this and the corporate way of breaking up is "hey we're gonna charge you 10x what did last year for this, kay?" (I don't know if it was actually 10x. It was just a LOT more)
So began the migration towards Kubernetes and AWS EKS. Snap was one of the pilot customers for EKS before it was generally available, iirc. (I helped work on this migration in 2018/2019)
Now, 6+ years later, I don't think Snap heavily uses GCP for traffic unless they migrated back. And this outage basically confirms that :P
Thats so interesting to me, I always assume companies like google who have "unlimited" dollars will always be happy to eat the cost to keep customers, especially given gcp usage outside googles internal services is way smaller compared to azure and aws. Also interesting to see snapchat had a hacky solution with AppEngine
