Amazon VPC CNI plugin increases pods per node limits

– 1 min read

Amazon VPC Container Networking Interface (CNI) Plugin supports “prefix assignment mode”, enabling you to run more pods per node on AWS Nitro based EC2 instance types. To achieve higher pod density, the VPC CNI plugin leverages a new VPC capability that enables IP address prefixes to be associated with elastic network interfaces (ENIs) attached to EC2 instances. You can now assign /28 (16 IP addresses) IPv4 address prefixes, instead of assigning individual secondary IPv4 addresses to network interfaces. This significantly increases number of pods that can be run per node.

A multi-cluster shared services architecture with EKS using Cilium ClusterMesh

– 1 min read

ClusterMesh is Cilium’s multi-cluster implementation that is built on top of Cilium CNI. It enables users to set up cross-cluster connectivity with standard Kubernetes semantics for transparent service discovery. Each cluster in the mesh participates as a peer. Cross-cluster traffic is handled by individual nodes rather than using a central gateway.
