Day-2 operations matter more than the first launch
Once an instance is live, good operations are about consistency: knowing how to reboot safely, resize intentionally, monitor behavior, and recover without improvising under pressure.Common instance operations
- Start, stop, reboot, and redeploy when needed
- Resize compute when traffic or workload shape changes
- Review CPU, memory, disk, and network behavior
- Attach or expand disks as data grows
- Manage backups, snapshots, and recovery readiness
Operating pattern that scales
1
Monitor real workload behavior
Use runtime metrics and application behavior to decide whether the instance is correctly sized.
2
Treat resizing as a planned change
Resize during a maintenance window or low-risk period when the workload is sensitive to interruption.
3
Keep backup and rollback paths current
Make sure your snapshot and restore assumptions are tested before high-risk changes.
Practical checks during routine management
- Has the workload outgrown the original disk plan?
- Are security rules still aligned with how the app is exposed today?
- Do old instances still exist after deployments or migrations?
- Are backups recent and restorable?
