How do VPC peering and Transit Gateway differ in terms of network connectivity and scalability?

Question

Prajna G · Accepted Answer

**VPC Peering** allows direct, one-to-one connectivity between two VPCs within the same region or across regions, suitable for simple network architectures, while **Transit Gateway** provides a scalable, hub-and-spoke model that connects multiple VPCs and on-premises networks, simplifying management and scaling for complex network topologies.
