Azure ExpressRoute

What is Azure ExpressRoute?

Azure ExpressRoute is a service that allows you to create private connections between Azure data centers and your on-premises infrastructure or colocation facilities. This connection does not go over the public Internet, offering more reliability, faster speeds, and lower latencies than typical internet connections.

Key Features

• Private connectivity to Microsoft Cloud services.
• High throughput and low latency.
• Redundant connections for reliability.
• Flexible billing options.
• Integration with networking services like Azure Virtual Network.

How It Works

Azure ExpressRoute works by establishing a dedicated circuit between your on-premises infrastructure and Azure. This is done through a connectivity provider. The connection can be either point-to-point or through a cloud exchange, providing flexibility in how you connect to Azure.

Setup Process

1. Choose a connectivity provider.
2. Configure your ExpressRoute circuit in the Azure portal.
3. Set up the connection with your provider.
4. Link your ExpressRoute circuit to a Virtual Network.
5. Test the connection.

Best Practices

Always monitor your ExpressRoute circuit for performance and reliability.

• Use redundant circuits for high availability.
• Implement Network Security Groups for enhanced security.
• Regularly review your bandwidth needs and upgrade as necessary.
• Test failover scenarios to ensure business continuity.
