Healthchecks.io has replaced its outsourced S3 service with a self‑hosted object store powered by Versity S3 Gateway and a Btrfs filesystem. The move eliminates per‑request costs and external dependencies while retaining the same API compatibility.

During 2024, the platform evaluated several cloud options, including AWS, OVHcloud, and UpCloud. Each presented performance or cost drawbacks, prompting the migration. The new setup runs on a dedicated server with NVMe RAID 1, delivering faster PutObject and GetObject calls.

Operational simplicity remains a priority: a single binary upgrade, systemd restart, and automated rsync backups keep the system lean. Daily encrypted backups sit off‑site, and the service has seen no outages in its first two weeks.

The switch reduces latency, shrinks upload queues, and removes a data‑processing partner. Though on‑prem costs rise, the performance gains justify the investment, and the team remains open to future optimizations.
