# ExpressRoute Port

ExpressRoute Port is a dedicated, high-capacity physical port that lets you connect your on-premises network directly to Microsoft's global backbone. It provides private, high-bandwidth connectivity for scenarios that need predictable performance and low latency. It supports dual ports for resilience and allows you to build large-scale private circuits without using shared connectivity models.
