The Real Cost of Running Kubernetes on AWS: 12 Places EKS Teams Waste Money
A comprehensive guide to identifying and eliminating hidden cloud infrastructure costs in Amazon EKS, from over-provisioned nodes to leaky cross-AZ traffic.
We don't just talk about cloud infrastructure. We build it, break it, and optimize it. Read our raw technical postmortems, architecture reviews, and deployment patterns.

A production engineering decision guide for choosing between EKS Auto Mode and Karpenter for Kubernetes autoscaling and cost optimization on AWS.

When startups complain about their AWS bill, they almost always blame compute. But when we audit their infrastructure, the real financial leaks are hidden elsewhere.

Getting your application running on AWS is only phase one. Here is the exact 4-week engineering blueprint to establish visibility, fix the architecture, and optimize costs before your first major bill.
