As the link says: The one and only thing that you cannot do is offer a commercial version of CockroachDB as a service without buying a license I like the idea and would support initiatives like this. If i really want to use CockroachDB then i'll install and maintain it myself on my own instances. In the long run this would also ensure that if i want to move away from AWS to another provider, i am not locked to an AWS service.
