En mi experiencia en los últimos años gestionando microservicios Java en clusters de Kubernetes en diferentes proyectos y consultorías. He notado que los principales problemas que afrontamos son: Escalabilidad eficiente de microservicios. Asignació...
In a previous post, we discussed installing Karpenter to manage cluster auto-scaling efficiently. You can find it here. Today, we'll explore how to further enhance cost savings on nodes by implementing automated shutdown and startup behaviors for Kub...
TL;DR — Optimizing EC2 costs in Kubernetes using Karpenter on AWS EKS involves leveraging auto-scaling features to adjust resource allocation dynamically, reducing operational costs. Key steps include setting up Karpenter, configuring NodeClass and N...
Introduction Helm is a package manager for Kubernetes that helps us to deploy custom applications and generate parameterized templates. This is very useful when it comes to deploying microservices on Kubernetes. Helm was accepted into CNCF on January...
TL;DR — In this post we will use the Grafana Open source Stack, using Prometheus, Loki, Tempo as datasources to obtain metrics, logs and traces respectively. We will also correlate the trace_id with Java metrics using Exemplars and we will instrument...
