I think companies like Cloudflare and fly.io are trying to tackle some of those multi-datacenter complexity issues you're describing. Those ridiculous egress fees appear to have peaked as well since Cloudflare announced their zero egress S3 competitor. I believe the way forward is not going back to self managed infrastructure. It looks like there will be sufficient competition to limit the most egregious price gauging. The way to avoid lock-in is to build on APIs that are at least somewhat portable. I know the portability devil is very much in the non functional details. But I think we'll see more of what happened with S3. Everybody will be adopting the more popular APIs. Over time we will converge on some new POSIX-like industry standard for the cloud.
