 # ExpressRoute connectivity models
-You can create a connection between your on-premises network and the Microsoft cloud in four different ways, [CloudExchange Co-location](#CloudExchange), [Point-to-point Ethernet Connection](#Ethernet), [Any-to-any (IPVPN) Connection](#IPVPN), and [ExpressRoute Direct](#Direct). Connectivity providers may offer one or more connectivity models. You can work with your connectivity provider to pick the model that works best for you.

 ## <a name="CloudExchange"></a>Co-located at a cloud exchange
-If you're co-located in a facility with a cloud exchange, you can order virtual cross-connections to the Microsoft cloud through the co-location provider’s Ethernet exchange. Co-location providers can offer either Layer 2 cross-connections, or managed Layer 3 cross-connections between your infrastructure in the co-location facility and the Microsoft cloud.

+If you're co-located in a facility with a cloud exchange, you can request for virtual cross-connections to the Microsoft cloud through the co-location provider’s Ethernet exchange. Co-location providers can offer either Layer 2 cross-connections, or managed Layer 3 cross-connections between your infrastructure in the co-location facility and the Microsoft cloud.
 
 ## <a name="Ethernet"></a>Point-to-point Ethernet connections
-You can connect your on-premises datacenters/offices to the Microsoft cloud through point-to-point Ethernet links. Point-to-point Ethernet providers can offer Layer 2 connections, or managed Layer 3 connections between your site and the Microsoft cloud.

 ## <a name="IPVPN"></a>Any-to-any (IPVPN) networks
-You can integrate your WAN with the Microsoft cloud. IPVPN providers (typically MPLS VPN) offer any-to-any connectivity between your branch offices and datacenters. The Microsoft cloud can be interconnected to your WAN to make it look just like any other branch office. WAN providers typically offer managed Layer 3 connectivity. ExpressRoute capabilities and features are all identical across all of the above connectivity models.

 ## <a name="Direct"></a>Direct from ExpressRoute sites
-You can connect directly into the Microsoft's global network at a peering location strategically distributed across the world. [ExpressRoute Direct](expressroute-erdirect-about.md) provides dual 100 Gbps or 10-Gbps connectivity, which supports Active/Active connectivity at scale.
