I like that it is an open source solution with great support for all major OS versions from Linux/Windows Server 2008R2 onwards as well which makes installation very easy across multiple environments (Dev / Test). It has been using Apache Traffic server version 1.* where there were some issues getting SSL certificates working but those have now resolved so we are back up & going! We require load balancing of different web apps hosted under various instances within our AWS environment - this enables us achieve greater reliability by spreading out traffic loads between several ECs rather than relying upon just one single instance being available at any given time etc..
