Vultr is a favorite cloud service of mine mostly due to the great customization options. They have a massive list of global locations, plan sizes, operating systems, snapshots plus custom ISO uploads. I have written a post on uploading Windows server 2016 to Vultr and Windows server 2012 r2. With these methods you can have a windows server for as low as $5.
This becomes even more attractive with Vultr now matching any funds you use on the platform. Its pity that this is only for new users though.
