Transit Gateway

Transit Gateway is a fully managed network transit hub that enables VPC-to-VPC and on-premises connectivity. It acts as a central hub for routing traffic between VPCs and external networks, providing a scalable and secure solution for VPC-to-VPC interactions.

With Transit Gateway, you can easily connect multiple VPCs and on-premises networks, simplifying network architecture and reducing administrative overhead. It supports a wide range of connectivity options, including VPN connections, Direct Connect, and VPC peering.

To set up Transit Gateway:

1. Create a Transit Gateway: In the AWS Management Console, you can create a Transit Gateway and configure its settings, such as the ASN (Autonomous System Number) and routing options.

2. Attach VPCs and on-premises networks: You can attach VPCs and on-premises networks to the Transit Gateway, allowing them to communicate with each other. This can be done through the AWS Management Console, CLI, or SDKs.

3. Configure route propagation: By configuring route propagation, you can control the flow of traffic between the attached VPCs and on-premises networks. This includes setting up route tables and defining the routing rules.

4. Enable transit gateway peering: If you have multiple Transit Gateways, you can enable transit gateway peering to establish connectivity between them, allowing for VPC-to-VPC communication across different regions or accounts.

Transit Gateway provides a centralized and scalable solution for managing VPC-to-VPC interactions, making it easier to connect and manage resources across multiple networks and locations.
