DNS/DHCP over WAN - complexity?

So I'm trying to look into hosting DHCP and DNS services somewhere centrally, instead of locally on each site.

First I want to find out what type of latency requirements there are (if any, aside from local solutions) on DHCP or DNS.

Second - how to deal with DHCP request going towards a different L3 'domain', i.e. over SDWAN to a different site. I'm not sure if this is even an issue, perhaps there's some relay required, no idea.

​

Do you guys have any experience with this? Perhaps I'm making this more complicated than it needs to be.
