The Horizontal Pod Autoscaler (HPA) has been running at maximum replicas for longer

If using basic metrics like CPU/Memory then ensure to set proper values for
`requests`.
For memory based scaling ensure there are no memory leaks.
If using custom metrics then tine tune how app scales accordingly to it.
For memory-based scaling, ensure there are no memory leaks.
If using custom metrics, fine-tune how the app scales according to it.

Use performance tests to see how the app scales.
