Hardware

CodeFloe runs on Hetzner Cloud¹. Hetzner brings many essential points to the table:

• great value/cost ratio
• GDPR compliance
• Terraform/OpenTofu provider
• VMs and bare-metal servers
• S3

These are effectively all the parts which are needed to run any service. Yes, a managed database is missing in that list. However, we are brave (enough) to roll our own database 🤓️, both to save costs and “because we can” 😉️.

Server Configuration

CodeFloe uses a mix of dedicated servers and cloud instances. The latter are great for small services and dev instances. However, they only have a small root disk which cannot be used for a Ceph cluster (as Ceph requires a dedicated storage device). Also the shared NVMEs on the cloud instances are good - but not as good as NVMEs from dedicated servers. This is why we acquired three dedicated servers. These come with two disks, of which one is used for a Ceph cluster and the other one for the database storage.

For CI/CD, we know that speed matters. Hence, an AX42 (artemis) and a Mac Mini M4 (gaia) process the builds for amd64 and arm64, respectively.

Note

The server names were inspired by the game “Horizon Forbidden West” 🎮️
