Managed VPS deployment reference

A VPS is only cheap if it is built properly once. The baseline below is applied at provisioning, not retrofitted after the first incident.

  1. 01

    Provider & provisioning

    Provider chosen on workload profile, data residency, network quality and support expectations u2014 not on headline price alone.

  2. 02

    Access control

    • Key-only SSH
    • Bastion or VPN entry
    • Non-root admin users

    Password authentication disabled, management ports closed to the public internet, per-person accounts with sudo logging.

  3. 03

    Host baseline

    • Hardened OS image
    • UFW / nftables
    • Fail2ban
    • Unattended upgrades

    Minimal package set, only required ports open, security updates applied automatically with reboot windows agreed.

  4. 04

    Application layer

    • Nginx / Caddy reverse proxy
    • Let's Encrypt automation
    • cPanel or Plesk (optional)
    • Docker services

    TLS renewal automated, services isolated per user or container, control panel added only where the client administers it themselves.

  5. 05

    Protection & visibility

    • Provider snapshots
    • Offsite backup copy
    • Uptime & resource monitoring
    • Log retention

    Snapshots are convenience, not backup u2014 an independent offsite copy is always configured alongside them.

Frequently asked questions

Which VPS provider should we use?

Contabo and Hetzner give the most resource per unit cost; DigitalOcean, Vultr and Linode give better network quality, APIs and support. The choice follows the workload, not a preference.

How is the VPS sized?

From measured load where an existing system can be profiled, otherwise a conservative baseline with monitoring and a review at 30 days u2014 vertical scaling on a VPS is a short maintenance window, not a rebuild.

Are provider snapshots enough protection?

No. Snapshots live in the same account as the server, so an account compromise or accidental deletion takes both. An independent offsite copy is always configured.

Do you manage the server afterwards?

Patching, monitoring, backup verification and hardening reviews can be covered under a maintenance arrangement agreed in advance, or handed over with documentation if you run it in-house.
