HAProxy and HAProxy Enterprise collect a vast amount of information about the health of your applications being load balanced.

As the world becomes more dependent on cloud-native systems, the tolerance for slow services is decreasing. Users expect instantaneous access to services, whether it's for work, entertainment, or even cloud infrastructure.
