Oracle Cloud Giving Away Ampere Arm A1 Instances Always Free

A few years ago we covered the Oracle Cloud Gets an Always Free Tier. Previously, one would get two AMD EPYC based compute VMs with 1/8 OCPU and 1GB of memory each. Let us call that what it is, not much. The bonus though is that, unlike the AWS Free Tier, this is an Always Free tier. Now, Oracle is upping the ante (significantly) with its new Ampere Arm A1 offering.

Although this has been announced for some time, the Oracle Cloud Ampere Altra offering is finally live. One can see that in the list of available “shapes” we have a bare-metal machine offering. These machines each have two Ampere Altra 80 core 3.0GHz CPUs. Beyond that, there is 100Gbps networking and 1TB of memory.

Why you are likely here though is due to the virtual machine. One can see this is Always Free Eligible. We can select the Ampere instance which is on the main Shapes listing not as a “specialty” instance type. Here we can make a VM.Standard.A1.Flex instance.

Flex allows one to configure the amount of CPU and memory in an instance. In the Always Free tier, we get four cores and up to 24GB of memory so, in theory, we could make smaller instances. Still, we decided to go big and make one large instance.

Above, you can see the quad-core Ampere Altra (A1) Arm instance with just over 46GB of storage and 24GB of memory. The overall setup takes minutes to get running.

Final Words

To us, this is a big deal. This is perhaps one of the best “free” instances that one can get. Something that we really like about Oracle’s Always Free tier is that one can use it without being as worried about overages as with Amazon’s offering. AWS has a size advantage, but Oracle has a great Always Free Tier offering.

Beyond the free tier, the pricing on the A1 instances is very low. We get $0.01/ hr per core costs as well as $0.0015/GB per GB hour of memory.

That makes the instance we have, less storage, worth around $0.076/ hour. To put this another way, the Amazon AWS EC2 a1.xlarge has 4 cores and 8GB of memory for $0.102 on-demand so Oracle is offering 3x the memory at about a 25% discount over what Amazon is offering.

Expect more on this from STH in the near future. As always, you can learn more about Ampere Altra on STH.


  1. Given Oracle has a reputation for shaking down customers locked into their platform I’m not sure I would trust their “always free” tier.

  2. I’m not seeing any free Altra instances in the AD-1 region, and it appears to be difficult or impossible to change regions once selected. Perhaps Altra is only available in AD-2?

  3. I wonder what, if anything, they are doing to keep the various cryptocurrency miners at bay.

    The bigger name ones are pretty much futile on CPU at this point, with either ASICs or GPUs having taken over; but there are some targeted at CPUs, even fairly low efficiency can be attractive if you don’t have to pay for it; and that’s an application that is both too cost-sensitive to be a good upsell proposition and willing and able to absorb all the resources it possibly can.

  4. I ran a benchmark and found a 4-core Ampere A1 instance is on average about three times faster than a Raspberry Pi 4B–much better on floating point about double on integer.

    I’m looking forward to future articles about the Ampere CPU and hopefully a comparison with the Graviton2.

  5. Eric, thanks for benchmarking. Indeed rpi4 does have 1.5GHz CPU and that will keep only if you take care about its cooling. Ampere seems to be going up to 3GHz e.g. 2x the freq of rpi4b which would suggest Ampere CPU cores are about the performance of A72 cores for the classical integer workload.

  6. I am not being allowed to select Ubuntu if I want to use all 4 cpu on 1 VM. I must use oracle linux to be able to do that. That is just shady.

  7. heisenberg I don’t see how that’s shady. Shady meaning deceptive, sly, disingenuous or at least something less than you reasonably expected.

    I have always assumed that you make some compromise in return for a gift, and actually having Oracle Linux on Ampere is obviously the reason why Oracle can give us these instances, because it counts for promotion.

    I say fair play to Oracle. I suppose the fact that still they’re being accused of deceptive practice by a gift horse dentist says that it’s early days yet for any hopeful PR recruits by the lakes.

  8. Nils, in the mid nineties Oracle especially in the Oracle 6 launch window so very aggressively sold rate reset licenses to get 6 out the door and into production, that it’s a testament to the chutzpah and abilities of their once extraordinary (additional adjectives usually provided by the room) sales teams, that nobody much believed that they wouldn’t pull it off. The result however was a inevitably protestant cohort (some felt like it was a generation) of executives whose bonuses got burned when licence prices reset upwards sharply.

  9. @heisenberg you can select ubuntu for any ARM . i also thought like that at first but there is ubuntu image that support that instance

    first, select shape arm and then choose an image as Conical ubuntu version 20.04 (not minimal)

  10. So what happens after the 30-days trial period ends?
    Do I have to re-provision the “always free” A1 VM?

    According to their official docs:
    “To continue using Always Free Arm-based compute instances, you must delete your existing Ampere A1 Compute instances and create new Ampere A1 Compute instances.”
