This document is targeted for customers interested in a deploying ECS with the Kemp LoadMaster family of ADCs/load balancers.
External load balancers (traffic managers) are highly recommended with ECS for applications that do not proactively monitor ECS node availability or natively manage traffic load to ECS nodes. Directing application traffic to ECS nodes using local DNS queries, as opposed to a traffic manager, can lead to failed connection attempts to unavailable nodes and unevenly distributed application load on ECS.
