If you are doing something for the web consider AWS or Azure. I use both and have found them extremely useful for my people. If you are doing things Linux based AWS with RDS can not be beat. If you are doing something with Microsoft consider Azure. There are a lot of pre-built AMI's or images available.
If you are on a pc VMWare is good, if you have any mac users parallels is better. There are free options but with that many people I'd check out one of the paid ones.
License wise you will need to investigate it but Microsoft offers 90 day licenses for Windows.
https://www.microsoft.com/en-u.... That is something I'm checking out as well. The thought is if your developer needs for testing only then throw away the virtual machine this is a good way to go.
I'm a fan of hiring professionals and making sure people know to not download anything that crosses their path. So opening permissions is great and gives them flexibility. I am not a fan of managed desktops, but know a lot of companies that use that. If you do open having a good anti-virus/firewall is a must.
BYOD is good for phones/tablets in that it saves you the cost, and people byod if you let them download mail, or slack or whatever on their I-Device or Droid. So would you rather the person see the email late at night on their phone or wait til tomorrow? I am not a fan of someone bringing their own laptop. If not whatever they are working on is on their own system when they exit the company.
Finally multiple monitors for individuals. You will be surprised at how much more efficient you can be with two monitors, or even 4. Myself I telecommute and am up to 9 now so multiple monitors is the best.
