Overview
A Transit Gateway (specifically an AWS service) acts as a central router for your cloud network. It simplifies network management by allowing you to connect thousands of VPCs and on-premises networks through a single hub, rather than managing complex peering relationships between every individual network.
Key Benefits
- Simplified Architecture: Reduces the complexity of 'full mesh' peering.
- Centralized Control: Allows you to manage routing and security policies in one place.
- Scalability: Easily add new VPCs or on-premises connections to the network.
- Inter-Region Support: Can connect VPCs across different geographic regions.
Use Case
Ideal for large organizations with many VPCs that need to communicate with each other and with a central data center.
