We moved our application over to Fly.io roughly a month ago. As it is an app which is currently in a beta-phase where there are not many users, it can easily run within the free 3x ‘shared-cpu-1x’ which Fly provides. As such, we did not expect to have any costs for November.
However, just now we did receive a credit card receipt containing costs for what is described as “Volume: SSD Storage (per GB/hr)”.
What exactly is this? The pricing page does not seem to mention it. It does mention “persistent volumes”, but this seems to be something else. (And we have not added any persistent volumes to our Fly cluster).
The usage tab of the Fly web-interface (e.g. Sign In · Fly ) also does not mention this metric.
