Today I noticed that there was a new update for MacOS Server that had quite a lengthy explaination:
As per Apple Knowledge Base article HT208312, the once great Apple Server product as this fall will be reduced to:
- Profile Manager
- Open Directory
The rationale of this is, according to Apple:
In fall 2018, Apple will stop bundling open source services such as Calendar Server, Contacts Server, the Mail Server, DNS, DHCP, VPN Server, and Websites with macOS Server. Customers can get these same services directly from open-source providers. This way, macOS Server customers can install the most secure and up-to-date services as soon as they’re available.
