2.2.11 Describe Azure ExpressRoute
Description of Azure ExpressRoute.
Description of Azure ExpressRoute.
ExpressRoute extends on-prem networks into the cloud over a private connection. This is called an ExpressRoute Circuit. This lets you connect offices, datacenters, or other facilities to the Microsoft Cloud. Each location will have its own ExpressRoute Circuit.
Connectivity can be from any-to-any network, a point-to-point Ethernet network or a virtual cross-connection. ExpressRoute does not cross the public internet.
Connectivity to Microsoft cloud across all regions in the geopolitical region
Global connectivity to Microsoft services across all regions with the ExpressRoute Global Reach
Dynamic routing from your network to Microsoft via BGP
Built-in redundancy
Microsoft Office 365
Microsoft Dynamics 365
Azure Compute Services
Azure Cloud Services like Azure Cosmos DB and Azure Storage
ExpressRoute Global can be used to connect ExpressRoute circuits. ExpressRoute Global can connect sites in Asia to Europe for example.
Uses BGP to exchange routes which enables dynamic routing from your on-prem network to services running in the Microsoft Cloud.
Each connectivity provider uses redundant devices to ensure connections with Microsoft are highly available.
CloudExchange colocation
Point-to-Point Ethernet connection
Any-to-Any connection
Directly from ExpressRoute sites
This is when your datacenter, office or other facility is located at a cloud exchange like an ISP. You can request a virtual cross-connect to the MS cloud.
Point-to-point ethernet connection uses a point-to-point connection to connect your facility to the Microsoft cloud.
Allows integration of a WAN with Azure by providing connection to offices and datacenters.
ExpressRoute Direct provides dual 100Gbps or 10-Gbps connectivity to Microsofts global network. This supports active/active connectivity at scale.
Data doesn't travel over the public internet, ExpressRoute is a private connection. However, DNS queries, certificate revocation list checking and Azure CDN requests are still sent over the public internet.
