Shared Bandwidth Overview

Shared bandwidth allows multiple EIPs to share the same bandwidth. All ECSs, BMSs, and load balancers that have EIPs bound in the same region can share a bandwidth.

When you host a large number of applications on the cloud, if each EIP uses an independent bandwidth, a lot of bandwidths are required, which significantly increases bandwidth costs. If all EIPs share the same bandwidth, you can lower bandwidth cost and easily perform system O&M.

  • Lowered Bandwidth Costs

    Region-level bandwidth sharing and multiplexing reduce bandwidth usage and O&M costs.

  • Flexible Operations

    You can add EIPs that are billed on a pay-per-use basis to a shared bandwidth or remove them from a shared bandwidth regardless of the instances to which they are bound.

  • Flexible Billing Modes

    The yearly/monthly and pay-per-use billing modes are provided.

Notes and Constraints

  • Only EIPs that are billed on a pay-per-use basis can be added to a shared bandwidth.
  • Shared bandwidths are billed by bandwidth or 95th percentile bandwidth (enhanced). If you select the bandwidth option, the minimum shared bandwidth that you can purchase is 5 Mbit/s. If you select the enhanced 95th percentile bandwidth option, the minimum shared bandwidth that you can purchase is 300 Mbit/s.
  • A maximum of 20 EIPs that are billed on a pay-per-use basis can be added to a shared bandwidth. If you want to add more EIPs to a shared bandwidth, submit a service ticket to request a quota increase.
  • Each account can have a maximum of 5 shared bandwidths. If you need more shared bandwidths, submit a service ticket to request a quota increase.
    • A dedicated bandwidth cannot be changed to a shared bandwidth and vice versa. However, you can purchase shared bandwidth for pay-per-use EIPs.
      • Add an EIP to a shared bandwidth to allow the EIP to use the shared bandwidth.
      • Remove the EIP from the shared bandwidth to allow the EIP to use the dedicated bandwidth.
