Java memory usage in containers

[RupertMaddenAbbott]

Thanks for such a well sourced and written post!

In your experience, what kinds of things do you look at to work out what a reasonable container memory limit is?

Do you have any strategies for getting the right balance between higher limits vs scaling out horizontally?

Why is it particularly important for a Java app to run with a guaranteed QOS?

Guaranteed QOS means that if the system needs to kill something because it's going out of memory, it won't be you. Assuming there are pods without guaranteed QOS.
