Explanation
AWS Transit Gateway is the correct service for connecting multiple VPCs. Here's why:
- AWS Transit Gateway acts as a central hub that can connect multiple VPCs, on-premises networks, and AWS services through a single gateway
- It simplifies network architecture by eliminating the need for complex VPC peering connections
Why the other options are incorrect:
- AWS Config: A service for assessing, auditing, and evaluating AWS resource configurations (not for networking)
- AWS Direct Connect: A service for establishing dedicated network connections from on-premises to AWS (not for VPC-to-VPC connectivity)
- Amazon GuardDuty: A threat detection service that monitors for malicious activity and unauthorized behavior (not a networking service)
Key Benefits of AWS Transit Gateway:
- Centralized management of VPC connectivity
- Simplified network topology
- Scalable solution for connecting multiple VPCs across different AWS accounts and regions
- Support for routing policies and network segmentation
