Summary

Sustainable operations require:

  1. Regular maintenance: Scheduled tasks prevent problems
  2. Incident readiness: Know how to respond when things break
  3. Backup discipline: Test your recovery process
  4. Documentation: Enable yourself and others
  5. Automation: Reduce toil and human error
  6. Cost awareness: Keep expenses under control

The goal is a system that runs reliably with minimal drama. Invest in operational practices early—they pay dividends over time.
