Hi Wynand,
While I'd hardly classify myself as an expert (after all and "ex" is a has-been, and spurt is a drip under pressure), but I have had quite an education since I started this thread, so here goes with my take on Foundation vs Essentials.
1. It's true that ONLY TWO concurrent RDS/RDG sessions can be running - these are only intenede for remote administration of the OS, not for actual operation - but up to 25 workstations can be
"Joined" to the Domain
and run concurrently.
2. Foundation, on the other hand only allows 15 concurrent users, any or all can be RDS/RDG users. CALs are ONLY required for RDS/RDG users, so if you'd have a mix of those AND joined workstation, you'd need CALs ONLY for the RDS/RDG
users.
I ended up purchasing a new server with Foundation - grabbed a fabulous deal from Dell, $845.00 for the whole magilla; hardware, OS and a year of Pro Support (24/7 North American support - I don't have to talk to Mujibar). I'm also in the final weeks
of a course in Administering Server 2012 R2 at our local Technical College, and after the first meeting, the course took away my intimidation to the server OS. I also purchased Mark Minasi's book, "Mastering Windows Server 2012 R2", a real
bible on the subject. With, only the book - the course didn't start till March '15, and I was setting my server up in October '14 - I was able to completely install all the roles and services I need, and configure the OS. I'm still very light on
Group Policy, but fortunately that will come in the next few class meetings.
To make a long story a little longer, here's my take on the decision between Foundation and Essentials:
1. If you're operation is based mostly on local workstations, with only a minimal of RDS/RDG that could be handled by no more that two concurrent sessions, then Essentials would be a good choice, since the setup and configurations are minimal.
2. If, on the other hand, your business, like mine, requires mostly RDS/RDG operation, then Foundation could be the better choice.
Because in my wife's business we're required to travel often, much of the operation is performed via RDS/RDG. I have two Workstations "Joined" to my Domain - one for my wife when wer're local, and one for a future in-office employee.
The beauty of RDG (Remote Desktop Gateway) over simple RDS is that when we're on the road, my wife can connect through the server gateway directly to her joined workstation, and work exactly the same as when she's sitting in front of it. With RDS, she'd
have to log into her domain account on the server itself, which provides a different desktop and apps. In addition, RDG is more secure since it uses port 443 (SSL/https) so the data is encrypted, as opposed to RDS which uses port 3389 and isn't encrypted.
This is essential to her business due to the very sensitive and personally identifiable information that she processes.
I was able to obtain a 5 user CAL pack for just over $100 from an internet site called "softwarejones" through Microsoft's open license plan - all perfectly legal because the actual license keys come directly from Microsoft - which provide
more than enough users for our current needs. If our "virtual office concept" business grows beyond that, more can be purchased at a good price.
I hope, if it's not too late already, that this helps with your decision. If you'd like to pursue this conversation further, you can do so directly with me via email at
