IIRC Zoom signed up with Oracle Cloud when COVID hit and they needed to scale like crazy.

I'm not sure if Zoom has any Critical infra in AWS though.

I interviewed there a few months ago for DevOps, and one of the people I interviewed with said that most of Zoom was in AWS (they liked that I had AWS stuff on my resume).
