<p id="vpc010004__p2509530598">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.</p>
