# Task Statement 4.4: Design Cost-Optimized Network Architectures

This study group focuses on **reducing network costs in AWS while ensuring performance and security**. We will explore **load balancing strategies, NAT gateway optimizations, network peering and routing strategies, AWS cost management tools, and content delivery techniques**.

We will follow **SecureCart**, an e-commerce platform, as they **optimize network connectivity costs, reduce data transfer fees, and implement efficient network architectures**.
