Explanation
Azure ExpressRoute provides a private, dedicated connection between on-premises data centers and Azure, bypassing the public internet.
The Azure service that allows businesses to extend their on-premises network to Azure with a dedicated, private connection is Azure ExpressRoute.
- Private, Dedicated Connectivity: Azure ExpressRoute establishes a private connection between your on-premises data center and Azure, bypassing the public internet entirely. This is achieved through a partnership with a connectivity provider, delivering a direct and secure link to Microsoft’s cloud.
- Enhanced Security and Reliability: Because ExpressRoute does not traverse the public internet, it offers greater security and privacy, reducing exposure to threats and providing more consistent, reliable connectivity. Each ExpressRoute circuit includes built-in redundancy with dual connections to Microsoft Enterprise Edge Routers (MSEEs), ensuring high availability and meeting stringent uptime SLAs.
- High Performance and Low Latency: ExpressRoute supports bandwidth options up to 100 Gbps, making it ideal for large-scale data transfers, business-critical workloads, and scenarios requiring low-latency, high-throughput connections between on-premises infrastructure and Azure.
- Global and Local Reach: The service enables connectivity to multiple Azure regions, supporting both local and global hybrid cloud architectures. Organizations can use ExpressRoute for connecting branch offices, disaster recovery, and global application deployments.
- Dynamic Routing and Integration: ExpressRoute uses BGP (Border Gateway Protocol) for dynamic routing between your on-premises network and Azure, supporting flexible and scalable network designs.
- Use Cases: Common scenarios include secure hybrid cloud deployments, data migration, high-performance computing, and ensuring compliance for sensitive workloads.
Azure ExpressRoute provides a private, dedicated connection between on-premises data centers and Azure, enhancing security, reliability, and performance by bypassing the public internet and supporting high-bandwidth, low-latency hybrid cloud integration.
