Once you've built a system that works well in production (and scales elastically, too, it seems), it is really difficult to switch out the underlying infrastructure. Makes sense about walking it back. The problem with running your own servers in data centers as a startup is that elasticity is genuinely a difficult problem to solve if you don't have a large budget for unused compute, storage, and so on. As we are seeing in Fly.io's case. Ultimately, my bet is that both startups end up as Heroku-like acquisitions for some large cloud company or another. I think that render will sell for a lot more because the value it provides is agnostic to the underlying cloud infrastructure.
