Some Express Connect partners have already connected their networks to the access points of Alibaba Cloud. You can choose these Express Connect partners if your data center is located outside the access point locations of Alibaba Cloud or your workloads do not demand high bandwidth. The Express Connect partner will create a hosted connection over the pre-installed Express Connect circuit from your data center to a virtual private cloud (VPC) on Alibaba Cloud.

Background information

  • An Express Connect circuit pre-installed by an Express Connect partner is shared by multiple tenants.
  • Shared Express Connect circuits provided by Express Connect partners are already connected to the access points of Alibaba Cloud. You need only to connect your data center to the access point of an Express Connect partner. Therefore, shared Express Connect circuits are best suited for users that have time efficiency demand.

    In most cases, when you use a shared Express Connect circuit to connect to Alibaba Cloud, the installation can be completed within one month while installing a dedicated Express Connect circuit is more time-consuming.

  • Alibaba Cloud offers shared ports. Express Connect partners can create shared ports instead of VBRs for tenants to manage their connections. Shared ports belong to tenants.

    Before you use a shared port, take note of the following changes made to the billable items:

    • The Express Connect partner is no longer charged an initial installation fee, VBR fee, or resource usage fee.
    • The tenant is charged a resource usage fee and outbound data transfer fee.

    For more information about the billing of shared Express Connect circuits, see Billing of hosted connections over Express Connect circuits.

  • After an Express Connect partner creates a shared port and transfers it to a tenant, the tenant must accept the shared port. Then, the tenant can create a VBR for the shared port. Each shared port can be associated only with one VBR.
  • Express Connect partners isolate resources based on the VLAN IDs of resources. Therefore, each hosted connection is assigned a VLAN ID. When a tenant creates a VBR for a shared port, the VBR must use the VLAN ID of the relevant hosted connection. The tenant is not allowed to change the VLAN ID of the VBR.
Notice Before you use a shared Express Connect circuit to connect to Alibaba Cloud, you must contact the Express Connect partner to negotiate a contract. The Express Connect partner bears responsibilities for any issues that are not covered by the terms of Alibaba Cloud network service level agreement (SLA).
