Running KVM VPS in Production in India: Operations Guide

Buying a VPS is the easy part. Keeping it healthy in production — through OS updates, disk-fill incidents, and the 2am alert nobody wants — is where teams either build good habits or get burned. Here's a baseline operations checklist.

Monitoring basics

• Set up uptime monitoring (synthetic checks) hitting your site every 1-5 minutes from outside the VPS
• Alert on disk usage above 80% — full disks are the single most common cause of avoidable VPS outages
• Watch memory and swap usage — heavy swapping is an early sign you've undersized the plan

Update discipline

Run apt update && apt upgrade (or your distro's equivalent) on a schedule, not "whenever." Security patches for OpenSSL, sudo and the kernel matter — unpatched VPS instances are the most common way small servers get compromised and turned into spam relays or crypto miners.

Backups you actually test

A backup you've never restored from isn't a real backup. Take VPS snapshots regularly, and once a quarter, actually spin up a test restore to confirm the process works before you need it in a real incident.

Basic incident response

• Keep a runbook — even a simple doc listing "how to restart nginx/MySQL/PHP-FPM" saves panic time
• Know where your logs live (/var/log/nginx, application logs) before you're debugging under pressure
• Have a rollback plan for deploys — know how to revert the last release quickly
