AWS Transit Gateway

AWS Transit Gateway

AWS Transit Gateway is used to connect your Amazon VPCs and on-premises networks through a central hub.

  • Central Hub Architecture: Acts as a cloud router that simplifies your network by eliminating complex peering relationships
  • Global Connectivity: As your cloud infrastructure expands globally, inter-Region peering connects transit gateways together using the AWS Global Infrastructure
  • Scalable Solution: Supports thousands of VPCs and on-premises connections through a single gateway
note

AWS Transit Gateway provides simplified network management, reduced operational overhead, and centralized connectivity control.

Use case: It can be used to connect multiple VPCs across different AWS accounts and regions, as well as on-premises networks through a single point of management.

  • Eliminates the need for multiple VPN connections and complex routing configurations
  • Supports both AWS Direct Connect and VPN connections for hybrid cloud architectures
  • Provides centralized monitoring and management through AWS CloudWatch and VPC Flow Logs
