 Another important criteria is the maximum number of pods the cluster can concurrently run. In a cluster using [native VPC networking](https://docs.aws.amazon.com/eks/latest/userguide/pod-networking.html) the maximum number of pods is limited by the [number of network interfaces in an instance](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI). [Here](https://github.com/awslabs/amazon-eks-ami/blob/master/files/eni-max-pods.txt) you can find a list of pod count limits per instance type.
 
-[Alernative pod networking solutions](https://docs.aws.amazon.com/eks/latest/userguide/alternate-cni-plugins.html) exist that lift the pod density limitation. This module supports using [Calico CNI](https://docs.projectcalico.org) to allow for a much higher number of pods per node. This is especially useful when many pods are expected to be running on the cluster, but they will be mostly idle.
+This module supports enabling [high pod density](https://aws.amazon.com/blogs/containers/amazon-vpc-cni-increases-pods-per-node-limits/) to overcome this limitation. See variable `enable_high_pod_density`.
