Add backend servers by specifying their ENIs

Overview

An elastic network interface (ENI) is a virtual network interface that can be attached to an Elastic Compute Service (ECS) instance in a virtual private cloud (VPC). ENIs can improve the availability of clusters and offer cost savings in service failovers and fine-grained network management. You can add a backend server to an SLB instance by specifying the primary or secondary IP address of the ENI used by the backend server.
