For multiple VPCs, the recommended approach is usually AWS Transit Gateway in a hub-and-spoke design.

NAVEEN KUMAR J · Answer

The recommended way to connect multiple VPCs depends entirely on the scale of your architecture and your traffic patterns. AWS offers two primary options to manage multi-VPC networking.1. AWS Transit Gateway (The Enterprise Choice)For architectures with three or more VPCs, or environments that connect back to an on-premises data center via AWS Direct Connect or VPN, AWS Transit Gateway is the gold standard.2. VPC Peering (The Point-to-Point Choice)If you only need to connect two or three VPCs that have non-overlapping IP address ranges, VPC Peering is the most efficient and cost-effective approach.
