Does it support third-party network plugins like Calico?

While it focuses on the native VPC CNI, it includes implementation guides for enabling native network policies and integrating Calico for enhanced security features.

Can I use this for both Application and Network Load Balancers?

Yes, it includes specialized templates and annotations for the AWS Load Balancer Controller to manage Layer 7 ALBs for web traffic and Layer 4 NLBs for TCP/UDP services.

How do I reduce cross-AZ data transfer costs in EKS?

The skill provides patterns for topology-aware routing and VPC Endpoints, ensuring traffic stays within the same availability zone and uses the AWS private backbone.

How does this skill help with EKS IP address exhaustion?

The skill provides detailed configurations for enabling Prefix Delegation and IPv6 modes within the VPC CNI, which significantly increases the number of available IP addresses per worker node.
