Pricing for multicore shared machine

I’ve been playing with machines and I’m really liking them so far. I’m unsure how much it will cost me though.

I’m starting a machine with these parameters:

"guest": {
    "cpu_kind": "shared",
    "cpus": 8,
    "memory_mb": 4096
}

The request works, so I believe it’s a valid machine. However, its cost isn’t listed here: Fly App Pricing · Fly Docs.

Would it be possible to add a formula for calculating price? How much should I expect to pay?

That’s a really good question! They’re a newer product, so they haven’t made it to our pricing page just yet. Since you’re using additional RAM too, this would be billed at around $25/mo.

Thanks for the response!

I have a few follow up questions:

  1. Is additional RAM any RAM used over 256 mb, so 3.75 GB for a 4 GB machine?
  2. $25/mo is assuming 24 hours a day for 31 days, correct? So it’s about 3.3 cents per hour.

Thanks for any clarification, I look forward to using fly.io more

always happy to help :slight_smile:

2GB additional ram. From the first link in my last post:

but they’re just multiplied by 2x, 4x, or 8x. So shared-cpu-8x costs about $14.72/mo and includes 2GB RAM.

From the second link:

If you had run the extra 256MB RAM for a whole 31-day month the RAM would have cost you about $1.30

  1. $25/month was a rough estimate from the $14.72 figure with 2GB additional ram to bring you to a 4GB total. Both of these were calculated for 31 days of continuous use:

so 2GB / 256GB = 8; (8 * $1.30/mo) + $14.72/mo = $25.12/mo

you can also see a preview invoice on your organization’s dashboard!
