Azure ExpressRoute connects on-premise networks into the Microsoft cloud over a private connection. Organizations can establish connections to Microsoft Azure or Microsoft 365.
ExpressRoute supports dynamic scaling of bandwidth on a best-effort basis.
The three connectivity options supported are:
- Point-to-point Ethernet connection
- Any-to-any (IP VPN) connection
- CloudExchange colocation (a virtual cross-connection through a connectivity provider at a colocation facility)
Connections do not go over public internet. This allows for faster speeds, better security, consistent latency and more reliability.
There are three billing models for ExpressRoute:
- Unlimited data - all inbound and outbound data transfer is charged for a flat monthly fee
- Metered data - all outbound data transfer is charged for per GB of data sent (transfer rates vary by region)
- ExpressRoute premium add-on - increases route limits and provides global connectivity for services across regions
ExpressRoute Direct provides connections into Microsoft's global network at peering locations strategically distributed across the world with dual 100 Gbps active/active connectivity.
