Microsoft has announced the general availability of Azure CNI Overlay, a new networking solution that assigns IP addresses from the user-defined overlay address space rather than using IP addresses from the VNET.
- Azure CNI Overlay uses the routing of these private address spaces as a native virtual network feature, which means that cluster nodes do not need to perform any extra encapsulation to make the overlay container network work.
- This allows the Pod overlay network to achieve the same performance as native VNET traffic and paves the way to support millions of pods across thousands of nodes.
