Hi! I wonder if there are any guidelines for choosing between scaling vertically or scaling horizontally using the Kubernetes autoscalers.
- When should one use the vertical autoscaler and when should one use the horizontal?
- Is it recommended to use both to acheive best performance?
- In the case that one uses both, what metrics are recommended?
- Also, is there any detailed explaination of how the VPA recommendation algorithm works? (I can’t find any documentation that goes into algorithm details anywhere)
Would be very grateful if anyone had answers to any of the above questions! Thank you.
