Azure Virtual Network Peering allows you to connect two or more Azure virtual networks (VNets) so that they can communicate with each other. This enables resources in the peered VNets to communicate directly. Virtual Network Peering can also enhance scalability.
Features
- Direct Communication: Resources in peered VNets can communicate with each other using private IP addresses.
- Low Latency: The connection is optimized for high performance with low latency.
- No Gateway Required: Peering does not require a VPN gateway, which helps reduce costs and complexity.
- Different Regions: You can connect VNets in different Azure regions (global peering), facilitating more versatile architectures.
- Security: Traffic between VNets remains private and is not exposed to the public internet.
Use Cases
- Isolated Development Environments: Peering can connect isolated environments for development, testing, and production.
- Multi-tier Applications: Connect different tiers (e.g., app, database) across VNets.
- Organizational Separation: Separate VNets for different departments while allowing necessary communication.
