What is the difference between Azure ExpressRoute and Azure VPN Gateway? Azure ExpressRoute: Azure ExpressRoute is a dedicated private network connection that provides a more reliable, low-latency, and high-throughput connection between your on-premises network and Microsoft Azure cloud. It is often used for connecting on-premises data centers or private networks directly to Azure, bypassing the public internet. ExpressRoute connections are established through a connectivity provider or partner, and it ensures a private and secure connection to Azure services.Azure VPN Gateway: Azure VPN Gateway, on the other hand, provides a secure encrypted connection between your on-premises network or client device and Azure's virtual network. It allows remote users or branch offices to securely access resources within Azure as if they were on the same network.
