# 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.
