Automatic Vertical Scaling in OpenJDK

Our News through WhatsApp


JVM-based applications are not fully container-ready, so cannot benefit from elasticity and density of this technology.
The first issue is that HotSpot JVM doesn’t release unused committed Heap memory automatically.

Find out more details what is done and how the added improvements improve resource consumption efficiency.
