I am wondering if windows server 2012 or 2016 is worth getting for our business. We are a small manufacturer / R&D company that is currently using windows home server 2012 as our 'server'. Our email is hosted by the same company that we rent our web server from. The windows home server is only really used for network storage / remote access to files, no domain controller or firewall or anything else. We are wanting to move to a PLM / PDM system for our CAD and BOM etc - but the software said it requires "Windows server" - so I am not sure if the home server will cut it. Basically, is there a cut down version of windows server we could get that isn't so costly ? - (the owners are loath to spend dollar one on just about anything IT related) - I saw a license for about $900 (no hardware) for windows server 2016 but I just don't know if it would be ok to use with the windows home server as the requirements are saying something about 8 core minimum license and 16 cores required or something .... (I didn't really understand them). tl;dr - whats the cheapest way to get a minimal windows server that will be used mainly for file sharing on the network / remote file access and SQL server / PDM / PLM server ?
