run my own authoritative DNS

Hello --

I have my DNS with a cloud provider that I want to stop using, and was considering where to move it (a few domains with a handful entries each). At some point I was wondering if I should run it myself. I have two VPS' in different data centers with fixed IP addresses, and I read up a bit - seems like this is doable. I am not set on what software to use. I would like it to run in a container. Does anybody have any recommendations, positive or negative?

Thanks :)
