Creating a Load Balancer
Function
This API is used to create a private network load balancer. After the load balancer is created, its details, such as load balancer ID, IP address, and subnet ID, are returned.
To create a public network load balancer, you also need to call the API for assigning a floating IP address and associate this IP address to the port bound to the IP address of the private network load balancer.
