Deployment patterns: AWS Network Load Balancer with Amazon EKS for Telco workloads

This article presents four deployment patterns for AWS Network Load Balancer (NLB) with Amazon EKS, designed for telecommunications workloads requiring high throughput, low latency, and network segmentation.

• Pattern 1: One NLB per Kubernetes service with automatic provisioning via AWS Load Balancer Controller
• Pattern 2: Single NLB for multiple services using TargetGroupBinding and NodePort, reducing infrastructure costs
• Pattern 3: NLB exposed via VPC Endpoint using AWS PrivateLink for traffic isolation across VRF segments
• Pattern 4: Multi-segment approach combining Patterns 2 and 3 for multiple VRF VPCs with single NLB
• Includes detailed deployment steps, configuration examples, and cleanup procedures for each pattern
• Demonstrates network segmentation and security through VPC Endpoints and PrivateLink integration

These patterns enable CSPs to optimize telco workloads on EKS with improved performance, reduced operational costs, and enhanced security through flexible network architecture.
