Kubernetes HPA sums resource usage across every container in a Pod, so Istio sidecars and logging agents dilute the scaling decision. Here's how the ContainerResource metric fixes it, in a K3s/Kubo context.
We deployed both Linkerd and Istio Ambient Mesh on K3s and compared them directly. From proxy architecture and real memory numbers to a K3s-specific CNI path pitfall, here is the decision framework for picking a service mesh on a lightweight K3s cluster.
A single checkout request was quietly triggering five separate service calls behind the scenes. The culprit isn't bad code — it's the "chatty call" architecture that Kubernetes microservices tend to fall into. This article explains the distributed N+1 problem and how to fix it.
You're great at subnet design, so why does Pod-to-Pod communication in Kubernetes trip you up every time? We break down the fundamentals of Kubernetes networking—CNI, Service Mesh, and NetworkPolicy—by contrasting them with traditional network design.
