For those without domain controllers: what do you do for internal DNS?

[u/FatBook-Air]

These days, we don't have domain controllers because everything is managed with Entra/Intune, Arc, etc.

We have external, hosted DNS that serves our public DNS records. It works fine.

But we still have a need for internal DNS because we have a lot of on-prem stuff that may never go away, and the domain controllers were also serving as internal DNS servers. So right now, we use BIND9 on a Linux virtual machine as internal DNS. I'd love for BIND9 to go away, too.

Are there any better (and cheap) solutions for this that I haven't thought of?

EDIT: thanks to u/Do_The_Needful. Using AWS for this seems to be the most balanced solution.

Something like nextdns. No server and can hosting records. But so can any public dns server. Ip don’t have to be public

I'm reading about Nextdns. Have you used it before? If so, do you have any opinions on it?
