Connectivity to Azure

Organizations can connect their own locations to Azure in a variety of ways, with bandwidth, security, and isolation being the key differentiators between possible connectivity options. Most Azure resources and services can be accessed via publicly available network addresses over the internet; however, variable network latency and security may be concerns for customers. Alternatively, customers can create “virtual networks,” which logically isolate customer resources in Azure and make them appear as part of the organization’s own network. Finally, an offering called ExpressRoute provides a dedicated line connecting the customer’s data center with an Azure region. The most expensive of the options, ExpressRoute provides the best bandwidth and lowest latency, but usually requires the participation of a local telecom provider.
