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.
Why Direct Connect?¶
Network quality: Direct Connect allows you to establish a dedicated network for data transmission, which brings high network performance, low latency, and excellent user experience.
Security: Direct Connect establishes private connectivity between your on-premises data center and the cloud. Data is transmitted over a secure dedicated connection.
Transmission speed: A connection supports a maximum of 10 Gbit/s bandwidth, meeting various bandwidth requirements.
Components¶
There are three key components for you to use Direct Connect: connection, virtual gateway, and virtual interface.
Connection
A connection links your on-premises data center and a carrier's physical network at the Direct Connect location you select.
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.
