ExpressRoute (now in public preview) is a dedicated, private, high-throughput network connection between Azure datacenters and on-premises IT environments. Connect your existing datacenters to Azure without flowing any traffic over the public Internet. Network quality-of-service is guaranteed. Use Azure as a natural extension of an existing private network or datacenter.
Start today with dedicated connections though Equinix datacenters, add Azure services to MPLS VPN provided by AT&T, or (through a new strategic partnership with Level3) create a private connection with Level3 Cloud Connect Solutions.
