Overview
What Is Direct Connect?
Direct Connect establishes a dedicated connection between your data center and the cloud. You can use one connection to access cloud computing resources in different regions, helping build a secure and reliable hybrid environment.
Application Scenarios
You need a dedicated network connection between your data center and a Virtual Private Cloud (VPC) to ensure high bandwidth, low latency, and robust security.
Components
There are three key components for you to use Direct Connect: connection, virtual gateway, and virtual interface.
- Connection
A connection is a dedicated network connection between your on-premises data center and a Direct Connect location over a leased line provided by a carrier. You can request standard connections.
A standard connection provides a port that is exclusive to you and allows you to have multiple virtual interfaces associated.
- Virtual gateway
A virtual gateway is a logical gateway for accessing a VPC. A virtual gateway can be associated with only one VPC. Multiple connections can access the same VPC through a single virtual gateway.
- Virtual interface
A virtual interface is an entrance for you to access VPCs through a leased line. A virtual interface associates your connection with a virtual gateway, which connects to a VPC so that your network can access the cloud.
