Server Essentials provide many “enterprise-level” features in one package designed for small business. It includes built-in hooks to cloud-hosted Office 365, Client system backups, and easy to manage remote access. I've installed many of these servers both existing and new installations at small businesses. I build the server into a rack mountable case that can be mounted in a full server enclosure or into a 19-inch equipment rack. It has a 25 user limit and up to 50 devices, but the best part is that no CALs (Client Access Licenses) are required.
