Description

On September 30, 2028, we’ll end support for Azure Network Policy Manager (NPM) on Linux nodes in AKS. To avoid disruptions, migrate AKS clusters running Linux nodes from NPM to Cilium Network Policy by that date.  

Transitioning to Cilium Network Policy for AKS clusters using Azure CNI powered by Cilium provides significant improvements, including: 

Robust support for Kubernetes-native policies. 
Powerful extended features such as Layer 7 policy, and Fully Qualified Domain Name filtering. 
eBPF-based architecture for packet processing, offering better performance, scalability and security.
