I sympathize with the authors of Varnish and nginx; their software is used all over the place, and they want to make a living at it. I just don't want to support that kind of business model, and I'm never dealing with per-server license compliance again. I wish more companies would model themselves after Percona: charge for support, custom engineering and on-call -- don't fork or paywall any code. ATS suffers by comparison, since there is no "ATS Inc." to provide support and engineering work. There's OmniTI, but I don't have first hand experience with their service to say if it's worthwhile or not. They did get paid to write the current ATS docs, so presumably they know what they're doing. I wish ATS got more attention, but it is after all a bit of a niche product hidden away in the Apache Foundation with a bunch of unrelated Java projects. It's too fiddly for small scale use, and once you hit large scale you're pretty much hiring someone from Yahoo or elsewhere that has experience running and developing it (for example: I'd like to hire ATS people). Doesn't give it a lot of opportunity to trickle into smaller shops and grow with their service.
