Amazon VPC Lattice is a fully managed service by AWS that simplifies service-to-service communication across VPCs and accounts. The CIDR blocks used by VPC Lattice are assigned and managed by AWS and are available through managed prefix lists for both IPv4 and IPv6.
To allow communication between your workloads (e.g., Pods in EKS) and VPC Lattice services, you must configure security groups, network ACLs, or resource policies to allow traffic from these AWS-managed prefix lists
Prefix List: A prefix list is a set of CIDR blocks (e.g., 192.0.2.0/24 for IPv4 or 2001:db8::/32 for IPv6) that represent a group of IP addresses.
AWS-managed prefix lists for services like VPC Lattice can be used in:
- ✅ Security Groups
- ✅ Route Tables
- ✅ Network ACLs
- ✅ Resource Policies
Security Groups Created by AWS for EKS
- Cluster Security Group (Control Plane to Worker Nodes)
- Node Security Group (Worker Nodes)
- Fargate Profile Security Group (if using AWS Fargate)
