Leveraging Azure ExpressRoute: Key Benefits
Azure ExpressRoute extends your on-premises networks into the Microsoft cloud over a private connection. This offers significant advantages over typical internet connections for enhanced performance, reliability, and security.
Improved Performance & Throughput
ExpressRoute offers higher bandwidth, lower latency, and more consistent speeds compared to standard internet connections. This is crucial for latency-sensitive applications and large data transfers.
Enhanced Security
By establishing a private connection, ExpressRoute bypasses the public internet. This significantly reduces the attack surface and protects your data from potential threats and interception.
Increased Reliability & Redundancy
ExpressRoute connections are designed for high availability. Coupled with redundant network paths and peering locations, it ensures your applications remain accessible even during network disruptions.
Cost Predictability
With predictable bandwidth and no data egress charges over the ExpressRoute connection, you can better manage your network costs compared to fluctuating public internet data costs.
Seamless Hybrid Cloud Integration
ExpressRoute enables a robust and secure hybrid cloud strategy, allowing you to connect your private cloud or datacenter seamlessly with Azure services for a unified IT environment.
Global Reach
Leverage Microsoft's extensive global network of peering locations to establish private connections from your offices or datacenters around the world to your Azure resources.
Key Scenarios Where ExpressRoute Shines
- Migrating large datasets or applications to Azure.
- Running mission-critical applications that require consistent performance and low latency.
- Establishing a secure and reliable connection between your on-premises datacenter and Azure.
- Connecting to Microsoft 365 services with enhanced performance and reliability.
Technical Advantages
ExpressRoute utilizes a variety of connectivity providers and offers different routing options:
- Provider-based connectivity: Partnering with a connectivity provider to establish your ExpressRoute circuit.
- Colocation facilities: Connecting directly from a colocation facility where Microsoft has a presence.
- Direct connection: Connecting directly from your datacenter to a Microsoft peering location.
With features like ExpressRoute FastPath, you can further optimize network traffic for specific workloads by bypassing the virtual network gateway for improved performance.
