    Server Load Balancer：CreateLoadBalancer

    更新時間：Nov 11, 2024

    Creates a Gateway Load Balancer (GWLB) instance.

    Operation description

    Make sure that you fully understand the billing methods and pricing of GWLB before calling this operation.

    • When you create a GWLB instance, the service-linked role AliyunServiceRoleForGwlb is automatically created.

    • CreateLoadBalancer is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the GetLoadBalancerAttribute operation to query the status of a GWLB instance.

      • If the GWLB instance is in the Provisioning state, the GWLB instance is being created.
      • If the GWLB instance is in the Active state, the GWLB instance is created.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
