Overview
AWS networking starts with Amazon VPC — your own virtual network with subnets, route tables, security groups, and gateways. AWS Transit Gateway connects thousands of VPCs and on-prem networks. AWS Cloud WAN gives a global, policy-driven backbone. At the edge, Amazon CloudFront (450+ POPs) delivers content with CloudFront Functions and Lambda@Edge for compute. Amazon VPC Lattice provides application-layer service-to-service connectivity across accounts and VPCs without complex peering.
Key concepts
- VPC design: subnetting, public vs. private, NAT, gateway types
- Hybrid: Direct Connect, Site-to-Site VPN, Cloud WAN
- CloudFront, AWS Global Accelerator, Route 53 routing policies
- Service connectivity: PrivateLink, VPC Lattice, App Mesh
- AWS WAF, Shield, and Network Firewall for security at the edge

AI-Powered EKS Troubleshooting with AWS DevOps Agent
Managing EKS clusters means correlating logs, metrics, IAM policies, and network configurations under pressure. The AWS DevOps Agent, announced at re:Invent 2025, changes this workflow fundamentally. In this session, you'll watch a live demonstration where the DevOps Agent autonomously investigates an EKS service failuretracing issues from Pod logs through VPC Security Groups without manual intervention. You'll learn how the agent correlates cross-service dependencies, generates verified remediation plans, and integrates into existing SRE workflows.

Active-Active Global Architecture with CloudFront and Route 53
In this lightning talk, we'll walk through a real-world architectural pattern used in production: combining AWS CloudFront with Route 53 latency-based routing to make your ECS-backed services truly global. Starting with the problem of slow response times for APAC users, we'll build up a practical active-active architecture step by step. You'll see how CloudFront sits in front of your regional ALBs, how WAF is woven into the design from the start rather than bolted on later, and why getting your domain configuration right — distinguishing between your ALB origin domain and your public-facing CloudFront alternate domain — is critical to making this pattern work correctly.
