Make sure you offer Windows Server. While to many of the guy's on this bored windows is not a necessity, for many enterprises or in-experienced users, windows is a must. Get your hands on Windows server 2012 R2 at the least.<p>I know all of my customers are very cost conscious and AWS and Azure's variable cost system scares them (Forget to turn off VPS, surprising amount of traffic all of a sudden), possibly bringing VPS's back to a fixed monthly cost that can compete with the big guy's?<p>I know I would personally love the heck out of a simple yet powerful UI, AWS is powerful but the UI looks terrible and is intimidating to a new user. Azure's UI looks fantastic however is lacking many easily features such as scheduling servers to go up and down, creating backups of data disks and VM's, etc(Instead relying on runbooks and Azure automation which requires them to become scripters).<p>Offer a year long free tier like AWS, a small 1 core 1GB RAM vps running a linux OS. This feature will bring many curious eye's your way, and while it may seem like you are throwing away your product, truly free will attract the eyes of many potential clients already indentured in AWS, Azure, DO, etc, who would have never bothered to spend the time otherwise.
