Cisco announced the end-of-support of their ACE load balancers as of Fall 2015. Cisco has executed on the end-of-life, end-of-service, and end-of-support plans for their Cisco ACE appliances. Enterprises that currently use Cisco ACE for their load balancing needs have been strongly encouraged to search for an alternative before time runs out and find a solution that will prepare them for the modern enterprise requirements.
In today’s business environment, enterprises need their load balancers to be elastic and provide network and app teams with the ability to get their job done faster. Applications have to be responsive to users, even when there is a sudden traffic spike. Users are used to an "always-on" experience and apps need to respond to these expectations. Web-scale companies such as Google and Facebook have relied on the combination of industry-standard data center hardware with powerful software that enables them to be agile, flexible, and elastic.
