I looked around a lot but the only thing I find is the statement from Microsoft: "Functionality is limited on Windows Server 2019 essentials" and comparison Charts comparing the Standard and DataCenter Editions...

So what exactly is limited in Essentials? (Beside the 25 User / 50 Devices Limit)

Can I use the Essentials Edition as Stand alone WebServer (without a Domain) using IIS and maybe a SQL Server Version installed on the Server on a hardware with 64 GB RAM and a single CPU with 12 Cores? Basically there is only a single user / Admin accessing the server. So the 25 User / 50 Device Limit would be more than OK.

Update: My Question ist NOT about Licensing it is about functionality and Limits. Licencing is clear. But still, if this is not the correct Forum for such a Question I can delete it...

  • This is esentially a licensing question. Your assumption that the single admin user is the only one that requires a license may be wrong. If your visitors log in or submit data, then you need CALs. – longneck Nov 07 '18 at 19:56
  • I'm voting to close this question as off-topic because licensing. https://serverfault.com/questions/215405/can-you-help-me-with-my-software-licensing-issue – longneck Nov 07 '18 at 20:00

Making long story short: No. You’ll have to provide some valid CALs and this isn’t what web server users typically have.

P.S. Get Datacenter edition. Or use FreeBSD and Apache. Both are free.

    Thanks for the link - this link makes clear, that users not using services of the Server but only of the website don't need a CAL. Otherwise you would never be able to use Windows as a Webserver serving thousands of users… - My question is NOT about Licensing, ist about functionality and limits (like only up to 64 GB RAM) – Markus Nov 08 '18 at 09:31
  • I do not understand why your answer is No. From that link 'Specialty Server' do not need CAL. So as long as it is licensed correctly per core count then it will be fine (licensing wise). But @Markus question was about features instead of license though. I believe the correct is Yes to both license and features. – Rosdi Apr 28 '21 at 09:56
