Have you had experience working with services where each container was run on its own JVM?

Yes, in some projects I have worked with microservices, where each service runs in a separate container with its own JVM. This approach allows isolating services from each other, facilitates scaling and updating individual components without affecting the entire system. For example, a separate JVM instance with the required Java version and dependencies is run in a Docker container, ensuring independence and stability of each service.
