How much RAM does Jenkins need?

Plan on 4 GB (8 GB for many agents) for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so Jenkins plus your other workloads fit in RAM with room to spare.

Development

The veteran, endlessly extensible automation server.

Automate builds, tests and deployments with thousands of plugins and full pipeline-as-code support.

When a team already knows Jenkins or needs a specific plugin, self-hosting keeps build credentials and artefacts in-house.

1
Provision a VPS
Pick a Debian/Ubuntu template and get root SSH in about a minute.
2
Install the runtime
Install Java + plugins (+ agents).
3
Deploy the application
Net what you need from the project’s official source and run it.
4
Put it behind TLS
Reverse-proxy with Nginx and issue a Let’s Encrypt certificate.
5
Add it to your backups
Include the data directory and database in your backup routine before you rely on it.

Give Jenkins its own database user with rights only on its own schema.
Reverse-proxy Jenkins and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep Jenkins patched — most self-hosting incidents are unpatched software.
