AWS Transit Gateway connects your Amazon Virtual Private Clouds (VPCs) and on-premises networks through a central hub. This connection simplifies your network and puts an end to complex peering relationships. Transit Gateway acts as a highly scalable cloud router—each new connection is made only once.
Transit Gateway Resource Information:
- Type of Resource: Generic monitorable resource
- Discovery type: AWS SDK discovery type
- Discovery profile selection: Resource can be discovered by “Transit Gateway” in the profiler
- ResourceTag: AWS_TRANSIT_GATEWAY
- Resource Unique Identification: gatewayId (gateway.transitGatewayId())
- Dependencies: Transit Gateway may depend on VPCs, route tables, and attachments for network connectivity
Transit Gateway Attachment Resource Information:
- Type of Resource: Generic non-monitorable resource
- Discovery type: AWS SDK discovery type
- Discovery profile selection: Resource can be discovered by “Transit Gateway Attachment” in the profiler
- ResourceTag: AWS_TRANSIT_GATEWAY_ATTACHMENT
- Resource Unique Identification: AttachmentId (attachment.transitGatewayAttachmentId())
- Dependencies: Transit Gateway Attachment runs on Transit Gateway and connects to VPCs or other resources
