In the ever-evolving world of Kubernetes, managing cross-availability zone (AZ) traffic is crucial for optimizing both performance and cost. Cross-AZ traffic can lead to increased latency and higher costs, affecting the efficiency of your applications. This blog will delve into practical strategies to minimize cross-AZ traffic, using real data, charts, and examples to illustrate these points effectively.

The Kubernetes Cluster Autoscaler is a powerful tool designed to manage the scaling of nodes in a cluster, ensuring that workloads have the resources they need while optimizing costs. However, certain pod configurations can hinder the autoscaler’s ability to bin pack efficiently, leading to resource waste. Let’s delve into the specific challenges posed by Pods with Pod Disruption Budgets (PDBs) that prevent eviction, Pods marked as safe-to-evict “false”, and those with numerous anti-affinity constraints.

Mastering Node Affinity in Kubernetes is crucial for optimizing workload placement within clusters, ensuring efficient resource utilization and performance.

Amazon Elastic Kubernetes Service (EKS) has become a cornerstone of modern container orchestration, allowing organizations to deploy and manage applications efficiently. One of the critical features that make EKS a powerful tool is its autoscaling capabilities.

Kubernetes is a powerful container orchestration platform that can help developers and DevOps teams deploy, manage, and scale applications more efficiently. However, with great power comes great responsibility. If you are not careful, it can be easy to end up with a complex and difficult-to-manage Kubernetes cluster. In this blog post, we will discuss some […]
