Why you need performance tests for proper Kubernetes scaling - Dmitry Chuyko

Zu diesem Termin dürfen wir wieder einen besonderen Gast bei uns begrüßen: Dmitry Chuyko ist Performance Engineer bei BellSoft und OpenJDK committer. Dimitry wird uns in seinem Vortrag "Why you need performance tests for proper Kubernetes scaling" erklären welche Rolle (automatische) Performance Tests für skalierbare Infrastrukturen auf Basis von Kubernetes spielen und anhand von einigen Beispielen Best-Practices erläutern.

Der Vortrag wird in englischer Sprache sein.
Talk & Slides will be in english.

Why you need performance tests for proper Kubernetes scaling

K8s helps enterprises with complex deployments and rapid scaling. But developers often solve only a part of the problem, i.e., withstanding a certain load. Hence, “default” containers behave unexpectedly leading to resource misuse, degradation, and huge cloud bills.
To remedy the situation, developers are to be involved in cost optimization with KPIs agreed with the business. From a technical standpoint, this means determining SRE metrics, building
efficient containers, and conducting performance tests.
In my presentation, I will show you how containers affect service behavior, and how microcontainers and native images help streamline the deployment. You will learn to measure performance and utilization and build container images differently.
By having clear goals and necessary optimizations in place during application delivery, you can reduce costs and make production safer.

Dmitry Chuyko is a performance engineer at BellSoft, an OpenJDK committer, and a public speaker. Prior to joining BellSoft, Dmitry worked on the Hotpot JVM at Oracle, and before that he had many years of programming experience in Java. He is currently focused on optimizing
HotSpot for x86 and ARM, previously being involved in rolling out JEP 386, which enables the creation of the smallest JDK containers. Dmitry continues his journey in the containerization process and is happy to share his insights and expertise in this field. Dmitry is a well-known
speaker in the Java community, and one of his recent public presentations is available here.

Dmitry is also a contributor to the DZone, and his most popular recent publications include:
