Azure ExpressRoute is a private highway to Microsoft's cloud, ensuring faster, safer, and more reliable connections.
Data avoids the internet when it passes through ExpressRoute - so it's super secure!
Four ways to use Azure ExpressRoute: Co-location at a cloud exchange, point-to-point Ethernet connection, any-to-any networks, and direct connections at peering locations.
Azure ExpressRoute is a private highway that connects your on-premise networks with the Microsoft cloud. This gives your on-premise networks access to Microsoft cloud services, like Azure. Your data doesn't travel over the public internet (this is super important!!), so it's faster, safer and more reliable than typical internet connections.
An ExpressRoute connection between your on-premise network and the Microsoft cloud is called an ExpressRoute Circuit. Each office, data centre or other on-premise facility would have its own ExpressRoute Circuit.
ExpressRoute supports four connectivity methods that you can use to connect your on-premises network to the Microsoft cloud:
*Cloud exchange: Think of it as a meeting place for clouds. It's where data centres or offices can connect directly to cloud services like Microsoft's.
**Virtual cross-connect: A secret tunnel to the cloud. If you're near a cloud exchange, you can ask for a private connection to Microsoft's cloud.
*An Ethernet connection uses a cable to transmit data between devices, such as computers, routers, and switches. It's known for its reliability and speed, making it a common choice for connecting devices within a local network.
*A Wide Area Network (WAN) is a network that connects multiple networks over a large geographical area, such as a city, country, or even across the globe. WANs are designed to facilitate long-distance communication and data exchange across different offices, data centres, or branches of an organisation.
ExpressRoute enables direct access to these services in all regions:
*Azure cloud services like Azure Cosmos DB and Azure Storage offer specific, managed services designed for particular data storage and database needs, reducing the operational overhead for those specific use cases. To compare, Azure compute services like Azure Virtual Machines provide more control and flexibility for running and managing custom applications.
