Microsoft Azure ExpressRoute Overview

Microsoft Azure ExpressRoute lets you to extend the on-premises networks into the MS cloud over the private connection facilitated by a connectivity provider. With ExpressRoute, you can establish the connections to MS cloud services, such as Microsoft Azure, Office 365, and D365.
Connectivity can be from an any-to-any (IP VPN) network, a point-to-point Ethernet network, or a virtual cross-connection through the connectivity provider at a co-location facility. ExpressRoute connections do not go beyond the public Internet. This lets Azure ExpressRoute connections offer more reliability, faster speeds, lower latencies, and higher security than connections over the Internet. For information on how to connect your network to Microsoft using ExpressRoute, see ExpressRoute connectivity models.

Benefits

Layer 3 connectivity between your on-premises network and the Microsoft Cloud through a connectivity provider. Connectivity can be from an any-to-any (IPVPN) network, a point-to-point Ethernet connection, or through a virtual cross-connection via an Ethernet exchange. Connectivity to MS cloud services across all regions in the geopolitical region. Global connectivity to Microsoft services across all regions with ExpressRoute premium add-on. Dynamic routing between your network and MS over industry standard protocols (BGP). Built-in redundancy in each peering location for higher reliability. Connection uptime SLA. QoS support for Skype for Business.

Features

Layer 3 Connectivity

Microsoft uses industry standard dynamic routing protocol (BGP) to exchange routes between your on-premises network, your instances in Azure, and Microsoft public addresses. We establish multiple BGP sessions with your network for the different traffic profiles. More details can be found in the ExpressRoute circuit and the routing domains article.

Redundancy

Each ExpressRoute circuit consists of two connections to two Microsoft Enterprise edge routers (MSEEs) from the connectivity provider/your network edge. Microsoft requires dual BGP connection from the connectivity provider/your side – one to each MSEE. You may select not to deploy redundant devices/Ethernet circuits at your end. However, the connectivity providers use the redundant devices to ensure your connections are handed off to Microsoft in a redundant manner. A redundant Layer 3 connectivity configuration is a requirement for our SLA to be valid.

Connectivity To Microsoft Cloud Services

ExpressRoute connections enable access to the following services: Microsoft Azure services, Microsoft Office 365 services and Microsoft Dynamics 365. Note: Software as a Service offering, like Office 365 and Dynamics 365, were created to be accessed securely and reliably via the Internet. Because of this, we recommend ExpressRoute for these applications only for specific scenarios. For information about using ExpressRoute to access Office 365, visit Azure ExpressRoute for Office 365. For a detailed list of services supported over ExpressRoute, visit the ExpressRoute FAQ page.

Connectivity To All Regions Within A Geopolitical Region

You can connect to Microsoft in one of our peering the locations and have access to all the regions within the geopolitical region. For example, if you connected to MS in Amsterdam through ExpressRoute, you have access to all Microsoft cloud services hosted in Northern Europe and Western Europe. For an overview of the geopolitical regions, the associated Microsoft cloud regions, and corresponding ExpressRoute peering locations see the ExpressRoute partners and peering locations article.

Global Connectivity With ExpressRoute Premium Add-On

You can enable the ExpressRoute premium add-on feature to extend connectivity across geopolitical boundaries. For example, if you are connected to MS in Amsterdam through ExpressRoute, you will have access to all Microsoft cloud services hosted in all regions across the world (national clouds are excluded). You can access the services which are deployed in South America or Australia the same way you access the North and West Europe regions.

Rich Connectivity Partner Ecosystem

ExpressRoute has a constantly growing ecosystem of connectivity providers and SI partners. For the latest information, refer to the ExpressRoute providers and locations article.

Connectivity To National Clouds

Microsoft operates isolated cloud environments for special geopolitical regions and customer segments. Refer to the ExpressRoute providers and locations page for the list of national clouds and providers.

Bandwidth Options

You can purchase ExpressRoute circuits for a wide range of bandwidths. Supported bandwidths are listed below. Be sure to check with your connectivity provider to determine the list of helped bandwidths they provide:50 Mbps, 100 Mbps, 200 Mbps, 500 Mbps, 1 Gbps, 2 Gbps, 5 Gbps, 10 Gbps.

Dynamic Scaling Of Bandwidth

You can increase the ExpressRoute circuit bandwidth (on a best effort basis) without having to tear down your connections.

Flexible Billing Models

You can pick a billing model that works best for you. Choose between the billing models listed below. For more information, see the ExpressRoute FAQ.

1.Unlimited Data

The ExpressRoute circuit is charged based on a monthly fee, and all inbound and outbound data transfer is included free of charge.

2.Metered Data

The ExpressRoute circuit is charged based on a monthly fee. All inbound data transfer is free of charge. Outbound information transfer is charged per GB of data transfer. Data transfer rates vary by region.

3.Azure ExpressRoute Premium Add-On

The ExpressRoute premium is an add-on over the ExpressRoute circuit. The ExpressRoute premium add-on provides the capabilities: Increased route limits for Azure public and Azure private peering from 4,000 routes to 10,000 routes. Global connectivity for services. An ExpressRoute circuit created in any region (excluding national clouds) will have access to resources across any other region in the world. For example, a virtual network created in West Europe can be accessed through an ExpressRoute circuit provisioned in Silicon Valley. Increased number of the VNet links per ExpressRoute circuit from 10 to a larger limit, that is depending on the bandwidth of the circuit.
