A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancers are used to increase capacity (concurrent users) and reliability of applications.

What is F5 load balancer and how it works?

F5 load balancer ensures seamless failover in cases where a server is down or overloaded. It redirects the traffic to other servers that could handle the load. HA deployment consists of two BIG-IP (like other load balancers) systems, synchronized with the same configuration: An active system that processes traffic.
