Global EIP Overview

A global Elastic IP (global EIP) can be bound to a global connection bandwidth for private communication and to a global internet bandwidth for Internet access. You can specify a global region and a global EIP pool to assign a global EIP, and bind a global EIP to a cloud instance (such as a load balancer or an ECS) from any region. To enable an ECS to communicate with the Internet through a global EIP, you also need to bind a global internet gateway to the global EIP.

Global EIP Quotas

If you want to increase your quota, see How Do I Apply for a Higher Quota?

Your request for a larger quota will only be approved if your account has valid orders and you are continuously using cloud resources. If you have released resources immediately after subscribing to them multiple times, your request for quota increase will be declined.
If you have increased the global EIP quota but you have not used the quota for a long time, Huawei Cloud will reduce the quota to the default value.

Notes and Constraints

Global EIPs cannot be used independently. You need to bind them to cloud instances, such as ECSs and load balancers. For details, see Binding a Global EIP to an Instance.
After a global EIP is bound to an instance, you need to bind a global connection bandwidth to the global EIP. For details, see Adding Instances to a Global Connection Bandwidth.

**Table 1** Process for binding a global EIP to an instance
No.	What You Need to Do	Description
1	Preparations	Buy a global internet bandwidth. A global internet bandwidth can only be shared by global EIPs from its same city. Buy a global connection bandwidth. Create a global internet gateway. To enable an ECS to communicate with the Internet through a global EIP, you also need to bind a global internet gateway to the global EIP. The global internet gateway and the ECS must be in the same region.
2	Assigning a Global EIP	Assign a global EIP and select a global internet bandwidth. You can add the global EIP to an existing global internet bandwidth or purchase a new global internet bandwidth. A global internet bandwidth can only be shared by global EIPs from its same city.
3	Binding a Global EIP to an Instance	To enable an ECS to communicate with the Internet through a global EIP, you also need to bind a global internet gateway to the global EIP. You can select an existing global internet gateway or create a new one.
