Krakow, Poland, 25 - 27 August 2021

Krzysztof Płachno


Developer traveling mostly via JVM lands, armed in Java and Scala, fighting with Web App dragons and pursuing Big Data quests. And because every fairly tale dream finally comes to an end, so needed I to leave my cozy programming comfort zone and get my hands dirty with operations stuff. And thus, willy-nilly, I became DevOps, which in fact turned out not to be that bad at all. Always willing to understand things in detail as well as to see them in wide picture view where they fit among others. Strong believer that technology is only a tool and that ultimately our goal is to solve end users problems.

Calibrating JVM on K8s

Cloud, Containers & Infrastructure

Developing a sound and efficient application is undeniably the biggest and the most complex part of creating a system. But still the operations part is something that might screw up all the coding effort. Especially, when rare app load peaks are making your system crash or become hardly usable. Of course, you can always negotiate with a manager bigger budget for infrastructure to triple the resources, explaining that highly resilient system costs money, but why not just understand the app resource consumption for good and configure it in effective way?

Talk given by Developer to Developers who are willing to broaden their scope of skills and responsibility and become more DevOps-like.
It will go from the very bottom to high top, starting with low details on how OS process allocates memory and how it's given CPU time, then how JVM relies on these system basics, up to how virtual machine cooperates with Docker containerization environment. All this to show how top level Kubernetes resource request/limit parameters is translated down to lower levels of abstraction.

Theory aspects chosen in pragmatic manner, enriched with live demos of tools that helps to calibrate execution parameters and monitor runtime performance.

Scheduled on Thursday from 14:40 to 15:30 in Room 4
