Design a Multi-VPC Network Architecture with Transit Gateway

ADVANCED
225 minutes
5 tasks

In this advanced lab, you will architect a complex, highly available, and resilient multi-VPC network architecture using AWS Transit Gateway. The goal is to interconnect multiple VPCs spread across different AWS regions, ensuring secure and low-latency communication. You will configure and verify routing policies, implement failover strategies, and integrate security protocols for seamless inter-VPC communication.

Scenario

TechCorp, an international enterprise, wants to enhance their existing AWS infrastructure by deploying a scalable multi-VPC networking solution. Currently, they have three distinct VPCs in us-east-1 and two in us-west-2. Each VPC supports different departments and requires cross-VPC communication for shared applications. The company aims for a sub-20ms latency in inter-VPC communication, with full redundancy in place to handle regional outages. To adhere to security compliance, all traffic should be logged and all connections must be encrypted using AWS Key Management Service (KMS).

Learning Objectives

  • Set up and configure AWS Transit Gateway for multi-VPC connectivity.
  • Implement routing policies to manage inter-VPC traffic.
  • Ensure secure communication by integrating AWS KMS and encrypting connections.
  • Implement monitoring and logging using AWS CloudTrail for compliance.
