Key Operations on ELB

Elastic Load Balancing (ELB) is a service that automatically distributes access traffic to multiple ECSs to balance their service load. ELB enables you to achieve higher levels of fault tolerance in your applications and expand application service capabilities.

With a web-based console, you can create load balancers, configure the ports required for listening, and add backend ECSs for load balancers. ELB helps eliminate single points of failure (SPOFs), improving availability of the whole system.

With CTS, you can record operations associated with ELB for later query, audit, and backtrack operations.
