All true except it being expensive though. I'm yet to find a major and reliable cloud service provider who can beat AWS on pricing. In fact, most either use or resell AWS under the hood themselves, even Vercel does as it turned out recently; and they're supposed to be one of the most competitive in the industry.

There are some rare exceptions who have their own large scale infrastructure and don't depend on AWS like Hetzner in EU, Alibaba Cloud in China or Ananta Cloud in India, but this market is still emerging.

So do it?

You are making the claim you see a clear massive global untapped market, for lower price and higher quality cloud/global compute, that you know how to provision and serve.

Apparently Signal will be happy to hear from you.
