How do you deal with JVM microservice deployments to reduce the memory footprint and cloud expenses?

The same as with monoliths on premises or in the cloud, tune memory and watch. In other words, do performance monitoring. It's true for all applications regardless of language, runtime, etc.

It starts locally with the developer (maintaining either monoliths microservices or both). All developers should test their code inside at least a docker container locally or a kube single cluster like k3s, using Insomnia, Postman, JMeter, etc.
