THE PROBLEM
Every IT infrastructure has components that are critical and need a setup to provide redundancy and scalability. Both to guarantee service uptime when something happens to one of the servers unexpectedly, but also to enable proactive maintenance in an easy way. Redundancy can be built into the application layer or be setup with DNS round-robin, but this adds complexity and does not always provide control to the service owner.
SOLVING THE PROBLEM
Built into the firewall that protects the hosted service is a server load balancing function can provide high availability with control. Without rewriting packets contents the solution can load balance protocol traffic including HTTP(S), DNS and LDAP and can utilize connection-rate and resource-usage based strategies. It can receive information through an API to dynamically change ratio of load distribution to the servers so that this can be decided by 3rd party process externally. This could be, mail queue, disk space, CPU usage etc.
