Henning Jacobs shares Zalando's approach to monitoring and optimizing Kubernetes resource requests and limits across dozens of clusters.

Крупнейшая профессиональная конференция для разработчиков высоконагруженных систем Saint HighLoad++ 2026 Подробнее: clck.ru/3QZHTb Июнь, 2026. Санкт-Петербург, DESIGN DISTRICT DAA in SPB  -------- HighLoad++ Moscow 2018 Тезисы и презентация: highload.ru/moscow/2018/abstracts/3933 Kubernetes has the concept of resource requests and limits. Pods get scheduled on the nodes based on their requests and optionally limited in how much of the resource they can consume. Understanding and optimizing resource requests/limits is crucial both for reducing resource "slack" and ensuring application performance/low-latency. This talk shows our approach to monitoring and optimizing Kubernetes resources for 80+ clusters to achieve cost-efficiency and reducing impact for latency-critical applications. All shown tools are Open Source and can be applied to most Kubernetes deployments. Нашли ошибку в видео? Пишите нам на support@ontico.ru

Why it's here

What people say. Recommended for its insights on setting CPU and memory requests and limits to balance cost-efficiency and application latency.

On “What we learned after a year of GitLab.com on Kubernetes”

…advised is to set memory limits equal to memory requests (guaranteed memory) while for CPU you can have limits > requests. And then there are some who say you shouldn’t bother with CPU requests at all except in special cases, because CPU requests can cause unexpected latency. There is a good YouTube video about all this by a Zalando engineer here: link to this video…
