Product Advantages
-
Flexibility
An EIP can be flexibly associated with or disassociated from an ECS, BMS, NAT gateway, load balancer, or virtual IP address. The bandwidth can be adjusted according to service changes.An EIP can be flexibly associated with or disassociated from an ECS, BMS, NAT gateway, load balancer, or virtual IP address.

Application Scenarios
Internet Egress
EIPs serve as egress filters for cloud resources to access the Internet and can be flexibly associated with or disassociated from various resources to meet service requirements.
Advantages
Flexible
An EIP can be flexibly associated with or disassociated from an ECS, BMS, NAT gateway, load balancer, or virtual IP address.
Cost-effective
Multiple billing modes are supported. Both yearly/monthly subscriptions and shared bandwidth reduce costs.
