Azure ExpressRoute is a cloud service offered by Microsoft that enables businesses to create a dedicated private connection between their on-premises infrastructure and Azure data centers. This connection provides higher security, reliability, and performance than traditional internet connections.
What is Azure ExpressRoute?
Azure ExpressRoute is a service that allows businesses to establish a dedicated, private connection between their on-premises infrastructure and Azure data centers. This connection bypasses the public internet, providing higher security, reliability, and performance.
Azure ExpressRoute is a hybrid cloud networking solution that enables businesses to extend their on-premises networks to Azure. This allows them to take advantage of the scalability, flexibility, and cost-effectiveness of the cloud while still maintaining control over their data and infrastructure.
How does Azure ExpressRoute work?
Azure ExpressRoute works by providing a private, dedicated connection between an organization’s on-premises infrastructure and Azure data centers. This connection is established using a dedicated physical connection or a virtual private network (VPN) connection over a service provider’s network.
Below are the steps to use Azure ExpressRoute:
Establishing a Connection
To use Azure ExpressRoute, a business must first establish a connection between its on-premises infrastructure and the Azure data centers. This can be done by setting up a dedicated physical connection or a virtual private network (VPN) connection over a service provider’s network.
Creating a Circuit
Once the connection is established, the business can create an ExpressRoute circuit, which is a logical representation of the connection between the on-premises infrastructure and the Azure data centers. The circuit is created by specifying the service provider, location, bandwidth, and other details.
Configuring Peering
After the circuit is created, the business can configure peering, which is the process of connecting to Azure resources through a private network. Azure ExpressRoute supports two types of peering: private peering and Microsoft peering.
Private peering connects the business to Azure resources directly, while Microsoft peering connects the business to Microsoft services such as Office 365 and Dynamics 365.
Managing Network
Traffic Azure ExpressRoute enables businesses to manage network traffic between their on-premises infrastructure and Azure resources. This can be done using network security groups (NSGs), which enable granular control over network traffic, and user-defined routing (UDR), which allows businesses to define their own routing policies.
Monitoring and Troubleshooting
Azure ExpressRoute provides several monitoring and troubleshooting tools that enable businesses to monitor the performance of their connections and troubleshoot any issues that may arise. These tools include Azure Monitor, which provides real-time monitoring and alerting, and Network Performance Monitor, which enables businesses to monitor network performance and troubleshoot connectivity issues.
