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. You can request standard connections and hosted connections.
A standard connection provides a port that is exclusive to you and allows you to have multiple virtual interfaces associated.
A hosted connection allows multiple users to share one port. Partners provision hosted connections and specify VLANs for those connections. Each user can associate only one virtual interface with a hosted connection. If a partner has created an operations connection, you can request a hosted connection from the partner, who will allocate the VLAN and bandwidth to your hosted connection.
- 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.
- Global DC gateway
A global DC gateway enables your on-premises data center to access VPCs in multiple regions so you can use a single connection to provide high-speed access to cloud compute and storage resources in any region.
A global DC gateway can only be associated with connections terminated at the same Direct Connect location. If there are multiple connections terminated at different Direct Connect locations, you need to create multiple global DC gateways.
- 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.
