Elastic IP

The Elastic IP (EIP) service provides public IP addresses. You can bind an EIP to a KEC, an EPC, or an SLB instance under your account. When an instance is faulty, you can detach the EIP from the instance and attach the EIP to another instance to ensure business continuity. EIP provides a variety of billing modes to address different business scenarios.

Benefits

Decoupling from Cloud Resources

Enable pooling of IP addresses and bandwidth, which allows you to bind EIPs to and unbind them from any KEC, EPC, or SLB instances in real time.

Reduced Bandwidth Cost

Provide a variety of billing modes to meet your requirements in different scenarios. You can select the appropriate billing mode based on your needs. The cost is calculated based on the bandwidth configured and no IP address retention fee is charged, helping you save bandwidth cost.

High Service Availability

An EIP can be associated with KEC, SLB, or EPC instances. When an instance is faulty, you can detach the EIP from the instance and attach the EIP to another instance. This way, service availability is improved.

Multiple Lines

Support a variety of lines with a maximum bandwidth of 15 Gbit/s to ensure stable lines for you.

Effective Resource Usage

You can add EIPs to BWS to make more efficient use of bandwidth resources.

Features

Resource Association

You can bind an EIP to any KEC, EPC, or SLB instance and unbind it from the instance at any time.

Flexible Bandwidth Adjustment

Bandwidth is flexibly adjusted based on business changes to achieve network elasticity.

Precise Billing

EIP supports Subscription and Pay-As-You-Go billing modes and provides precise billing to minimize your cost.

Flexible Use

You can add EIPs in the same region and of the same billing mode and line type to BWS to improve resource utilization.
