This topic describes how to create an Edge Load Balancer (ELB) instance to forward client requests to backend servers.
Before you create an ELB instance, you need to plan the region of the ELB instance and create a VPC and a vSwitch based on your business requirements.
Activate Edge Node Service (ENS). For more information, see Activate ENS.
Create a VPC and a vSwitch.
To use the ELB service, you need to create an ELB instance. An ELB instance is an entity that provides load balancing services.
Configure the ELB instance.
Configure a listener: You can add a listener for the instance and add backend servers to distribute traffic to multiple backend ENS instances based on the listener policies.
Configure backend servers: You can add at least one ENS instance as the backend server of the ELB instance to receive requests that are forwarded by the ELB listener.
Optional. Resolve a domain name.
Use Alibaba Cloud DNS to resolve a domain name to the IP address of the ELB instance. Then, the ELB instance can provide external services.
