No One Puts Java in the Container - Ken Sipe, Mesosphere

Sign up or log in to save this to your schedule and see who's attending!

Whether it is Docker or the Mesos Container running with Apache Mesos means running in a container, but do you really understand cgroups and how they work? Do you understand the difference between CPU Sets and CPU Shares? Many organizations use Java for their application development, but do you understand the consequence of what impact the cgroup constraints have on the JRE?

This talk starts with a look at the anatomy of a container including control groups (cgroups) and namespaces. Then we will take a deep understand of Java's memory management and GC characteristics and how JRE characteristics change based on core count. The session will detail specifically the difference between CPU sets and CPU shares and memory management. The session will close with a deep understanding of the consequences of running the JRE in a CPU share environment and the potential for pseudo-random behavior of running in a heterogeneous datacenter.
