 # Azure Peering Service overview
 
-Azure Peering Service is a networking service that enhances customer connectivity to Microsoft cloud services such as Microsoft 365, Dynamics 365, software as a service (SaaS) services, Azure, or any Microsoft services accessible via the public internet. Microsoft has partnered with internet service providers (ISPs), internet exchange partners (IXPs), and software-defined cloud interconnect (SDCI) providers worldwide to provide reliable and high-performing public connectivity with optimal routing from the customer to the Microsoft network.

Microsoft has partnered with internet service providers (ISPs), internet exchange partners (IXPs), and software-defined cloud interconnect (SDCI) providers worldwide to provide reliable and high-performing public connectivity with optimal routing from the customer to the Microsoft network.
 
 With Peering Service, customers can select a well-connected partner service provider in a given region. Public connectivity is optimized for high reliability and minimal latency from cloud services to the end-user location.

 Customers can also opt for Peering Service telemetry such as user latency measures to the Microsoft network, BGP route monitoring, and alerts against leaks and hijacks by registering the Peering Service connection in the Azure portal. 
 
 To use Peering Service, customers aren't required to register with Microsoft. The only requirement is to contact a [Peering Service partner](location-partners.md) to get the service. To opt in for Peering Service telemetry, customers must register for it in the Azure portal.

 ## Background
 
 Microsoft 365, Dynamics 365, and any other Microsoft SaaS services are hosted in multiple Microsoft datacenters and can be accessed from any geographic location. The Microsoft global network has Microsoft Edge point-of-presence (PoP) locations around the world where it can connect to an end user via their service providers. 
 
 Microsoft and partner service providers ensure that the traffic for the prefixes registered with a Peering Service connection enters and exits the nearest Microsoft Edge PoP locations on the Microsoft global network. Microsoft ensures that the networking traffic egressing from the prefixes registered with Peering Service connections takes the nearest Microsoft Edge PoP locations on the Microsoft global network.
