ENS:Create an ELB instance

Prerequisites

• The region of the ELB instance is planned. ELB does not support cross-node deployment. The ENS instances that you add to an ELB instance and the ELB instance must be in the same region.

• A custom network and a vSwitch are created. The ELB instance to be created will be deployed in the custom network.

Create an instance

1. Log on to the ENS console.

2. In the left-side navigation pane, choose Edge Load Balancer > Classic Load Balancer.

3. On the ELB Instance page, click Create Instance.

4. On the Edge Load Balancer page, configure the parameters. The following table describes the parameters.

   Parameter	Description
   Billing Method	Only Pay-as-you-go is supported.
   Instance Name	Specify the name of the ELB instance.
   Region	Select the region to which the instance belongs. Make sure that the ENS instances that you add to the ELB instance and the ELB instance are in the same region.
   Network	Select a custom network.
   vSwitch	Select a custom vSwitch.
   Instance Type	Estimate the maximum number of concurrent connections and the QPS that the ELB instance to create needs to handle based on your business requirements before you select an appropriate instance type. For more information about the performance metrics of different instance types, see Instance types.

5. Read and agree to ENS Terms of Service, and click Confirm.

• Configure a listener to listen for connection requests and forward the requests to backend servers based on a specific scheduling algorithm. For more information, see Configure a listener.

• ELB instances that are created in the ENS console are internal-facing instances and are not publicly accessible. To allow an ELB instance to access the Internet, you need to associate an elastic IP address (EIP) with the ELB instance. For more information, see Associate an EIP.
