Advantages

EIPs can be flexibly bound to or unbound from ECSs, BMSs, NAT gateways, load balancers, or virtual IP addresses. The bandwidth can be scaled according to service changes.

EIPs are available on a pay-per-use (billed by bandwidth or traffic) or yearly/monthly (billed by bandwidth) basis. You can use shared bandwidth to enjoy lower bandwidth costs. Generally, if you have frequent data transfer needs, a yearly/monthly subscription is a more cost-effective option.

EIP binding, unbinding, and bandwidth adjustments take effect immediately.

A global EIP can be bound to a global connection bandwidth for private communication and to a global internet bandwidth for global internet access. You can specify a global region to assign a global EIP, and bind a global EIP to an instance (such as an ECS or a load balancer) in any region on the cloud.

Global EIP binding and unbinding take effect immediately. You can modify global connection bandwidths and global internet bandwidths as required.
