Fly seems to have a fantastically generous free tier, but the numbers are a bit unclear. The free tier says “Run 3 shared-cpu-1x VMs full time.” And the pricing page has rates for the VM types “shared-cpu-1x”, “dedicated-cpu-1x”, “dedicated-cpu-2x”, etc.
But then on my billing page, under “Firecracker VM exec time,” it says I have 4d of “micro-1x” compute time and 35s of “cpu1mem1” compute time. Are those aliases of “shared-cpu-1x”?
Am I correct in my understanding that the free tier ends when the sum of my “micro-1x” and “cpu1mem1” time exceeds 97 days per month (8,436,960 seconds)?
