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.
Note
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, 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.
Easy to Manage
Region-level bandwidth sharing and multiplexing simplify O&M statistics, management, and operations cost settlement.
Flexible Operations
You can add 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.
Note
Do not add EIPs of the dedicated load balancer type (5_gray) and other types to the same shared bandwidth. Otherwise, the bandwidth limit policy will not take effect.
