                Best practices: administrate a Substrate-based chain
              
          
    Best practices for maintaining & running substrate-based (para)chain (wip)


Ensure all of your systems are kept up-to-date, especially with security updates.
Ensure you can fully bootstrap a new system from scratch easily if needed.
Upload archive chain backups frequently. Potentially make these available to the community down the road.
Have database recovery methods in place.
Use infrastructure as code. Never modify anything manually on your servers.
Ensure you have a monitoring stack set up WITH alerts (alertmanager/grafana alerts/bots etc).
Keep alerts actionable, otherwise they become noise.
If a service crashes, make sure it automatically restarts in some way (via systemd or kubernetes).
