Pricing virtual assets is hard
//
imo the thing to look out for is actual vendor / architecture lock-in. So just don't make things complicated yourself... Docker has it's uses, but right now it's being used for literally everything. I've been using jails, vms, and containers since the 90s. Docker is niceish, but somehow got lots of attention.
Oh, and you need to be sure your platform won't eat all your revenue.. like oracle :)
Especially on servers, and especially if for some stupid reason licensed software need internet access to confirm it is licensed, coz that's extra crap that needs to be added on proxy or firewalls and will inevitably break when they change something.
If it's "hey, pay us X and we trust you don't cheat us" yeah, it's just extra invoice ,whatever.
