I'm a fan of DO too. In terms of "what's missing?", how about the equivalent of AWS Lambda@Edge or Cloudfront EdgeWorkers? ie, a NodeJS runtime as close to the end user as the nearest CDN edge.
The problem with Runtime at Edge is that they are extremely engineering intensive, given it isn't just hosting but the whole software stack involved. ( See CloudFlare Workers for Example ) Which is sort of outside the sweet spot that DO is currently enjoying or operating in. I am not sure if it is a sound strategic decision to persuade. Although I would certainly love to see competition in that area.
Well yeah, if you care enough about performance that it matters whether the "server" runtime is at the data center or the edge, it's kind of a given it won't all be completely automagic. But it is, thankfully, becoming an increasingly straightforward path to tread.
We were going to call it that, bought the domain names and everything, but a competitor registered a trademark on the name the week before we launched. Oops.
