Azure ExpressRoute

Describe Azure ExpressRoute

In this lesson, you will learn about Azure ExpressRoute, its features, benefits, and connectivity models. Azure ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection, enhancing reliability, speed, and security.

Introduction to Azure ExpressRoute

Azure ExpressRoute is a service that allows you to create private connections between Azure datacenters and your on-premises infrastructure or colocation facility. This private connection, called an ExpressRoute Circuit, provides enhanced performance and security compared to typical internet connections.

Features and Benefits of ExpressRoute

Azure ExpressRoute offers several key advantages for connecting your on-premises network to the Microsoft cloud:

  • Direct Connectivity : Connect directly to Microsoft cloud services across all regions within your geopolitical area.
  • Global Reach : Use ExpressRoute Global Reach to connect multiple on-premises sites globally.
  • Dynamic Routing : Utilize Border Gateway Protocol (BGP) for dynamic route exchange between your network and Microsoft.
  • Built-in Redundancy : Achieve higher reliability with redundant devices in every peering location.

Connectivity to Microsoft Cloud Services

ExpressRoute provides direct access to a wide range of Microsoft services, including:

  • Microsoft Office 365
  • Microsoft Dynamics 365
  • Azure compute services (e.g., Azure Virtual Machines)
  • Azure cloud services (e.g., Azure Cosmos DB, Azure Storage)

Global Connectivity

With ExpressRoute Global Reach, you can link your on-premises locations worldwide by connecting their ExpressRoute circuits. For example, if you have offices in different continents, you can use Global Reach to enable secure communication between them without using the public internet.

Dynamic Routing

ExpressRoute employs BGP to facilitate dynamic routing…
