In conjunction with the vJUG and the Silicon Valley Java User Group, the vJUG is conducting a 24 hour virtual conference. Our session will be one of the 24.
No One Puts Java in the Container
The current craze of Docker and micro-services has everyone sticking their processes inside a container… but do you really understand cgroups and how they work? Do you understand the difference between CPU Sets and CPU Shares? Do you understand the consequence of what impact the cgroup constraints have on the JRE? This talk starts with a deep understand of Java’s memory management and GC characteristics and how JRE characteristics change based on core count. We will continue the talk looking at containers and how resource isolation works. 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.
