Our runners are running on our own infrastructure. We get bare metal instances from providers like Hetzner or Leaseweb and virtualize them. Your runners run on the ephemeral VMs on those bare metal instances.

Is being on AWS a requirement for you? Is it because of caching? We also have our own runner cache. You can find more information from here https://www.ubicloud.com/docs/github-actions-integration/ubi...

If you have more questions, please let me know or alternatively you can send us a mail from support@ubicloud.com
