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
Monitor real workload behavior
Use runtime metrics and application behavior to decide whether the instance is correctly sized.
Treat resizing as a planned change
Resize during a maintenance window or low-risk period when the workload is sensitive to interruption.
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?
