Applying for an EIP and associating an ECS

This section describes how to associate an Elastic IP Address (EIP) with an Elastic Compute Service (ECS) instance to help you quickly master the use of EIPs.

Ensure the total of your available balance and vouchers applicable to the EIP is no less than CNY 100.00, with the available balance not less than 0. For details, see Recharge guide.

Create an ECS instance without any EIP associated. For details, see Purchasing an instance.

Procedure

Associate the EIP with an ECS: Associate the newly applied EIP with the prepared ECS instance.

Verify: Log in to the prepared ECS instance and test its connectivity with the internet.

Step 1: Apply for an EIP

In the top menu bar, select region and project. This example selects China (Beijing) and default.

Click Apply for EIP.
