Centralized / Hub

You have applications running in multiple VPCs/VNet. You would like to secure all the applications through a centralized security services VPC/VNet. This model deploys the Multicloud Defense Gateway in a service VPC. You attach all the application VPCs (Spoke VPCs) and the Services VPC to the AWS Transit Gateway or VNet/VPC peering in Azure and GCP. Multicloud Defense provides an option to orchestrate the AWS Transit Gateway, Services VPC and the Spoke VPC Attachments. This is the recommended solution for ease of deployment, removing the complexity of multiple route tables and Transit Gateway attachments.
