Give your business a strong backbone

Get fast and scalable performance for your most important apps and services. Take advantage of a global backbone network that connects hundreds of edge nodes and data centers—the same network that supports enterprise and consumer services such as Microsoft 365, Bing, and Xbox.

Get intelligent and adaptive security

Reap the rewards of a network that can rapidly predict, emulate, and respond to issues and anomalies. The Azure global network is an agile, software-defined networking (SDN) technology, based on top of commodity hardware, and developed in collaboration with Microsoft Research and the open source community.

Stay close to the cloud

Run your apps and services on edge nodes that are interconnected to thousands of unique internet partners in more than 130 locations. Whether you access Microsoft services through the internet or through a private connection such as ExpressRoute, you’re always milliseconds away from Azure. And, once you’re on the global network, you stay on it. Your traffic remains between the datacenters, never over the internet.

Gain from decades of experience

Get the benefits of more than two decades of Microsoft investments in infrastructure cable. The network is one of the world’s largest and most reliable cable systems, with more than 70000 miles of fiber optic and subsea cable connecting 54 Azure regions and 130 edge node locations. Your apps and services run on secure routing that scales to meet your needs anywhere in the world—and your traffic never leaves the network.

Run your apps on the latest innovation

Take advantage of an innovative network that reliably rolls out updates in hours instead of weeks. The Azure global network encompasses hundreds of datacenters and thousands of switches, and is powered by a customized switch operating system developed by Microsoft. The Software for Open Networking in the Cloud (SONiC) is perfectly aligned to the Azure SDN platform and supported by industry-leading vendors.
