Running Java on Kubernetes? CPU and memory limits affect much more than scheduling.

A 4 GiB heap requires a container larger than 4 GiB. Fractional CPU limits can also change the processor count that HotSpot sees.

In our new article, you will learn:

- Why JVM heap size and container memory are different boundaries
- How CPU limits affect garbage collection, worker pools, and application performance
- Which JVM and container metrics to collect when validating resource settings under load

The article also includes practical experiments and an interactive configuration calculator.
