Short answer: both are credible bases for a small VPS. Choose based on provider image support, package and update cadence, available documentation, required tooling, and the operator’s recovery skills—not distro loyalty.
Which should a small team choose?
Choose Debian when a conservative base, broad community documentation, and minimal vendor coupling fit the workload. Choose Ubuntu when provider images, ecosystem documentation, or Ubuntu-specific tooling reduce operational friction. Confirm what your VPS provider actually supports.
Compare the decisions that affect operations
- Lifecycle: verify official support dates for the exact release.
- Images: confirm cloud-init, recovery console, and snapshot behavior.
- Packages: check whether required software is available in supported repositories.
- Security: use the distro’s advisory and update channels.
- Recovery: practice restoring the service, not only reinstalling the OS.
For existing systems, see Debian server security review and Ubuntu 26.04 kernel triage.
