Elastic IP Address (EIP)
Alibaba Cloud’s Elastic IP Address allows you to manage public IPs independently to improve internet network quality. This service is designed for networking scenarios where you need flexible IP management rather than static assignments. It functions as a standalone resource that can be detached and reattached to different instances, providing stability for your public-facing services.
Choose this solution when you require persistent public IPs that survive instance state changes. Be aware there is no free tier available for this service. The pricing model operates on a pay-as-you-go basis, meaning you will incur costs based on usage without any initial free allowance to offset those expenses.
