Direct Connect

Shared Line

Shared Line overview

Building a Direct Connect Connection from the on-premises data center to the VolcanoEngine access point independently entails substantial costs and certain construction timeline. Therefore, using a DC connection of a line operator that is already connected to the VolcanoEngine access point is a better solution. This only requires completing the last-mile line construction between the on-premises data center and the operator access point, significantly reducing construction time.

What is Shared Line

Shared Line refers to an access mode where tenants apply to a line operator who has connected the VolcanoEngine access points to share the operator's DC Connection. In this mode, tenants only need to establish a network between the on-premises data center and the operator access point. They can use the DC service via the Shared Line created by the line operator.

When multiple tenants share the same DC Connection between the operator access point and the VolcanoEngine access point, all tenants' Shared Lines share the bandwidth of the DC Connection. Therefore, Shared Line is suitable for low-bandwidth services.

The line operator applies to VolcanoEngine to enable the Shared Line feature, and creates a Shared Line for tenants. The tenant accepts and uses the Shared Line.

After completing the installation of DC Connections between the operator access point and the VolcanoEngine access point, the line operator only needs to assist the tenant in completing the line installation and network connection between the tenant's data center and the operator access point. Compared to Dedicated Lines, Shared Lines generally have shorter construction periods and suit businesses with tighter cloud migration timelines.

If creating a Shared Line for multiple tenants, the line operator needs to assign the VLAN ID. Tenants isolate resources based on the VLAN ID.
