Azure global infrastructure is made up of two key components—physical infrastructure and connective network components. The physical component is comprised of 300+ physical datacenters, arranged into regions, and linked by one of the largest interconnected networks on the planet.
With the connectivity of the global Azure network, each of the Azure datacenters provides high availability, low latency, scalability, and the latest advancements in cloud infrastructure—all running on the Azure platform.
Together, these components keep data entirely within the trusted Microsoft network and IP traffic never enters the public internet.
