What is this?
Enterprise networking on AWS combines VPCs, Transit Gateway, Direct Connect, PrivateLink, and hybrid DNS for hub-spoke and multi-account topologies.
Why should you care?
AwsVerse connects branch offices and SaaS pods through Transit Gateway with centralized inspection.
See it live — copy this example
Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).
aws ec2 create-transit-gateway \
--description "AwsVerse hub" \
--options DefaultRouteTableAssociation=enable,DefaultRouteTablePropagation=enable \
--tag-specifications 'ResourceType=transit-gateway,Tags=[{Key=Name,Value=awsverse-tgw}]'What happened?
- Creates a Transit Gateway as network hub.
- Attach VPCs and VPN/DX; propagate routes instead of full mesh peering.
Practice next
- Sketch hub-spoke: shared services VPC plus workload VPCs.
- Create TGW; attach one spoke VPC in lab.
- Review route tables propagation vs static routes.
- Attach a second VPC and verify propagated routes.
- Compare TGW data processing vs NAT costs for east-west.
Remember
TGW scales multi-VPC routing. PrivateLink for service consumption. Hybrid via DX or Site-to-Site VPN.
AwsVerse network hub
Ten SaaS accounts need shared logging VPC.
Outcome: TGW connects spokes; one firewall VPC inspects egress.
