Bring your own cloud
OEC.sh's page says
“All Cloudpepper plans are hosted on Cloudpepper's infrastructure only - no option to use your own cloud provider (AWS, Hetzner, DigitalOcean, etc.).”
The facts
You can bring your own cloud. Connect servers from AWS, Google Cloud, Azure, Hetzner, Vultr, DigitalOcean, OVHcloud — or any server over SSH, in any region, with full root access. You pay your provider directly; Cloudpepper adds no markup. Cloudpepper-managed servers are an option, not a requirement. See pricing.
