Server Load Balancer (SLB) is a traffic distribution and control service that distributes inbound traffic among several backend servers, namely ECS instances, based on configured forwarding rules. SLB expands the serving capacity of applications and enhances their availability.

By setting a virtual service address, SLB virtualizes added ECS instances into a server pool that offers a high level of performance and high availability. SLB distributes client requests to ECS instances in the server pool based on forwarding rules.

SLB also checks the health status of added ECS instances, and automatically isolates unhealthy instances to eliminate Single Point of Failures (SPOF), improving the overall serving capacity of your application. Additionally, working with Alibaba Anti-DDoS, SLB can defend against DDoS attacks.

Setup

To set up the OpsRamp Alibaba integration and discover the Alibaba service, go to Alibaba Integration Discovery Profile and select Server LoadBalancer.
