| Category | HPA (Horizontal Pod Autoscaling) | VPA (Vertical Pod Autoscaling) |
|---|---|---|
| Data Consistency | Can cause data inconsistency if it scales down a pod that is still processing requests or updating data | Can cause data inconsistency if it restarts a pod that is still processing requests or updating data |
| Data Availability | Can cause data unavailability if it scales down a pod that is holding a lock or a leader role | Can cause data unavailability if it restarts a pod that is holding a lock or a leader role |
| Data Migration | Can cause data migration if it scales up a pod that needs to copy data from other pods | Can cause data migration if it changes the resource requests or limits of a pod that affects its placement on nodes |
