This is why our BYOC pricing is less than our Dedicated Hosting pricing, as the costs listed for BYOC are only what you pay for ScaleGrid and don’t include your hardware costs. While this is a good way to get a rough estimate, your monthly cloud costs will indeed vary based on the amount of backups performed and your data transfer activity.

I had always been an advocate for the Windows AMIs – as most of the world runs Windows instead of Linux, I wanted the performance to represent what the majority sees.
