VPS Hosting and Operations

A VPS is a rented Linux box with a public IP address. That is the whole product — everything else is work you do, and the interesting part of that work is the second week rather than the first.

Reach for one when you want predictable cost, no vendor-specific runtime, and the ability to run anything that runs on Linux. Databases, background workers, long-lived connections and self-hosted tools all fit here and often fit poorly elsewhere.

Reach for a managed platform instead when nobody on the team wants to be responsible for kernel updates at 2 a.m., or when the workload genuinely needs to scale horizontally without warning.

The failures are consistent across every provider. Firewalls that look correct but do not cover published container ports, because Docker manipulates iptables directly. Disks that fill with unrotated container logs. Backups that have never been restored. And a single administrator SSH key with no second path in, so one misconfigured sshd_config means rebuilding the machine.

Day-two operations is the part that separates a server that survives from one that is quietly rebuilt every few months. Unattended security upgrades, monitored disk usage, log rotation, tested restores, and a firewall you have verified by scanning from somewhere else — none of it is difficult, and all of it is skipped more often than not.

The articles here assume Ubuntu LTS and Docker, state the exact versions they were run against, and verify the result from outside the host rather than from inside it.
