Kubernetes

I’ve noticed that questions about scaling workloads in Kubernetes remain consistently high and don’t decrease over time. Many users struggle with scaling their workloads effectively and don’t know the optimal approach. While many rely on the default Horizontal Pod Autoscaler (HPA), which has its limitations, this often leads to the creation of custom scripts and tools. I’d like to introduce you to KEDA (Kubernetes Event Driven Autoscaler), an excellent tool for scaling workloads in Kubernetes. KEDA is a lightweight component that works alongside HPA and significantly extends its capabilities. ...

Introduction Topology Aware Routing (TAR) is a Kubernetes feature designed to keep traffic within the same availability zone (AZ). This can reduce cross-AZ traffic costs on cloud providers like AWS and GCP, where inter-AZ traffic incurs charges. Additionally, it can lower latency by keeping network requests local. However, TAR is not a silver bullet. While it helps optimize costs and performance, it strictly prohibits cross-zone traffic, regardless of the system’s health or workload distribution. This limitation can lead to unintended service disruptions. ...
