Networking

This batch covers the network foundation that EKS runs inside. Start with the concepts — VPC, subnets, availability zones, IP planning — then build the VPC with Terraform. Every resource in later batches depends on this being correct.

Networking concepts VPC basics, subnets, AZs, VPC CNI IP planning, security groups, endpoint access modes, and what EKS needs from the network.

VPC Create the VPC, public and private subnets, NAT gateway, route tables, and EKS subnet tags.
