Explanation
Azure ExpressRoute provides a private, dedicated connection between on-premises data centers and Azure, offering better security and lower latency than VPNs.
The best Azure service for securely integrating an on-premises network with Azure in a hybrid cloud scenario is Azure ExpressRoute.
- Private, Dedicated Connectivity: Azure ExpressRoute establishes a private, dedicated connection between your on-premises data center and Azure, bypassing the public internet entirely. This enhances security, reduces exposure to internet-based threats, and ensures data privacy.
- High Performance and Reliability: ExpressRoute offers higher reliability, faster speeds, and consistent, low-latency connections compared to VPN solutions that use the public internet. It is ideal for mission-critical workloads and large-scale data transfers, supporting bandwidths up to 100 Gbps.
- Compliance and Security: By avoiding the public internet, ExpressRoute helps organizations meet stringent compliance and regulatory requirements. Additional security measures, like network security appliances and encryption options (MACsec for ExpressRoute Direct, IPsec for end-to-end), can be configured for enhanced protection.
- Built-In Redundancy: Every ExpressRoute connection includes redundancy at the peering location, providing high availability and failover capabilities to ensure continuous service.
- Flexible Connectivity Models: ExpressRoute supports multiple connectivity models, including point-to-point Ethernet, any-to-any (IPVPN), and connections via colocation providers, making it adaptable to various enterprise networking needs.
- Global Reach: With the ExpressRoute premium add-on, organizations can achieve global connectivity to Microsoft services across all Azure regions, supporting multinational and distributed architectures.
Comparison with Azure VPN Gateway:
- ExpressRoute is best for enterprises needing high-speed, private, and reliable connections for hybrid cloud integration.
- VPN Gateway is more cost-effective and easier to configure but relies on encrypted tunnels over the public internet, which may introduce higher latency and less consistent performance.
Azure ExpressRoute provides a private, dedicated connection between on-premises data centers and Azure, delivering enhanced security, reliability, and performance for hybrid cloud integration—making it the preferred solution for organizations with demanding security and compliance requirements.
