This certainly is not the server of yore with Xserve. Those glory days (or what was left of them by the end of it) died with in 2009 with the end of 10.6 Server. Though, having dealt with Macs in the Enterprise for years, I'm not 100 percent certain that they were all that great even then either. Linux has always seemed more powerful and Windows Servers, for all their issues, dominate large orgs for good reasons. However, macOS Server has some strengths Namely 1) It is intended for a small maybe even medium sized business, as far as the services go. For what you can do here for 20 dollars USD, its pretty great. File sharing, VPN, Contacts w/ a built in GAL, customizable Calendar, a relatively basic but useful intranet (Wiki) and the ability to host websites by basically dropping your folder of HTML/CSS/Python/PHP/Javascript code into a folder is very neat. Its also fairly trivial to setup a small mail server. 2) Ease of deployment. Goes along with number 1, but to specifically address those talking about a UPS and the need for other higher-end server fucntions. I DO NOT disagree :) However, it is, compared to a rackmount server, trivially inexpensive to setup a replica of a macOS Server. Just buy another mac mini, join the open directory to the existing master, and BOOM import your data. You know have a backup server. and you can do this dozens of times if needed. With a few button clicks, and, for what its worth, it also does some semblance of reasonable load balancing of the services too with you have replicas. Cool eh? 3) The real Gem here though is Profile Manager. Companies like Meraki/Airwatch/Microsoft charge an arm and a leg for mobile device management solutions that are basically clones of Profile Manager (with some exceptions. JAMF is pretty neat) Automatically enrolling devices into profile manager or now apple school manager is super simple, there is limited network setup you have to have, and it maintains itself very easily. This also lets you push tho VPP apps as well. And there is no per user cost. No per device cost. Profiling is just as robust as any other MDM solution like inTune Airwatch, MobileIron etc. Macs & iOS devices can be provisioned with zero touch enrollment. And soooooo much more. And no more apple IDs! Have users on your AD or LDAP instance? Join the mac itself to that instance and flip on the open directory, and boom, you can use your AD/LDAP credentials for your mobile devices and macs. All for under 800 bucks. Its a steal.
