Exploring AKS networking options

Setting up a big Kubernetes cluster in Azure? Azure-CNI overlay mode is a good pick for the right scenario. However, it comes with trade-offs as it may impose restrictions on CNI plugin upgrades, patch releases, and supported features.

But if you're after more control, like tweaking settings , BYOCNI with Calico is the way to go.

Calico adds some serious muscle to your network game, making things more efficient and secure. In short, Azure-CNI is great for an all-rounder, while BYOCNI with Calico is perfect for tailor-made setups.


Monitoring Kubernetes clusters activity with Azure Managed Grafana and Calico
