How does F5 Load Balancing Work?
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.
What is F5 load balancer?
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 load balancer and how it works?
