Memory Footprint of the JVM
The JVM can be a complex beast. Thankfully, much of that complexity is under the hood, and we as application developers and deployers often don’t have to worry about it too much. With the rise of container-based deployment strategies, one area of complexity that needs some attention is the JVM’s memory footprint. In this post you can see the two kinds of memory, the differences between them, native memory areas, JVM sizing and what does this all mean for Spring, so be sure to check it out!
