What Are the Differences Between a Dedicated Bandwidth and a Shared Bandwidth? Can a Dedicated Bandwidth Be Changed to a Shared Bandwidth or the Other Way Around?

Dedicated bandwidth: The bandwidth can only be used by one EIP and the EIP can only be used by one cloud resource, such as an ECS and a NAT gateway.

Shared bandwidth: The bandwidth can be shared by multiple EIPs. You can add multiple pay-per-use EIPs to the bandwidth. Adding an EIP to or removing an EIP from a shared bandwidth does not affect running services.

A dedicated bandwidth cannot be changed to a shared bandwidth or the other way around. However, you can purchase shared bandwidth for pay-per-use EIPs.

  • After an EIP is added to a shared bandwidth, the EIP will use the shared bandwidth.
  • After an EIP is removed from the shared bandwidth, the EIP will use the dedicated bandwidth.
