Shared Bandwidth Overview
A shared bandwidth can be shared by multiple EIPs and controls the data transfer rate on these EIPs in a centralized manner. All ECSs, BMSs, and load balancers that have EIPs bound in the same region can share a bandwidth.
- A shared bandwidth cannot control how much data can be transferred using a single EIP. Data transfer rate on EIPs cannot be customized.
When you host a large number of applications on the cloud, if each EIP uses a bandwidth, a lot of bandwidths are required, which significantly increases bandwidth costs. If all EIPs share the same bandwidth, you can lower bandwidth costs 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 pay-per-use EIPs (except for 5_gray EIPs of dedicated load balancers) to or remove them from a shared bandwidth regardless of the type of instances that they are bound to.
- Flexible Billing Modes
The yearly/monthly and pay-per-use billing modes are provided.
You can use a shared bandwidth in either of the following ways:
- Assign a shared bandwidth and add your pay-per-use EIPs to the bandwidth.
- Assign a shared bandwidth, set Billed By to Shared Bandwidth and select the shared bandwidth when you assign EIPs.
Notes and Constraints
- If a yearly/monthly shared bandwidth is deleted upon expiration, EIPs sharing the bandwidth will be removed from the bandwidth and be billed based on the mode before they are added to the shared bandwidth.
- A shared bandwidth can only be used by resources from its same account.
- A dedicated bandwidth cannot be changed to a shared bandwidth and vice versa. However, you can purchase a shared bandwidth for pay-per-use EIPs.
- Add an EIP to a shared bandwidth and then the EIP will use the shared bandwidth.
- Remove the EIP from the shared bandwidth and then the EIP will use the dedicated bandwidth.
