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 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 a bandwidth, a lot of bandwidths are required, increasing O&M workload. If all EIPs share the same bandwidth, VPCs and the region-level bandwidth can be managed in a unified manner, simplifying O&M statistics and network operations cost settlement.
- A shared bandwidth cannot control how much data can be transferred using a single EIP. Data transfer rate on EIPs cannot be customized.
Advantages
- Lowered Bandwidth Costs
Region-level bandwidth sharing and multiplexing reduce bandwidth usage and O&M costs.
- Easy to Manage
Region-level bandwidth sharing and multiplexing simplify O&M statistics, management, and operations cost settlement.
- 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.
Methods of Using a Shared Bandwidth
You can use the shared bandwidth in either of the two ways shown in the following table.
|
Description |
Step |
|---|---|
|
Method 1: Assign a shared bandwidth and add your pay-per-use EIPs to the bandwidth. |
|
|
Method 2: Assign a shared bandwidth, set Billed By to Shared Bandwidth and select the shared bandwidth when you assign pay-per-use EIPs. |
