Hardware NLB (Network Load Balancing) is a type of load balancing which is implemented at the hardware level. It is typically used for high-traffic websites or applications. It works by distributing incoming traffic across multiple servers, ensuring that no single server is overloaded. An example of hardware NLB is F5 Big-IP load balancer.
Software NLB (Network Load Balancing) is a type of load balancing which is implemented at the software level. It is typically used for smaller websites or applications which do not require the same level of performance as hardware NLB. It works by distributing incoming traffic across multiple servers, ensuring that no single server is overloaded. An example of software NLB is Windows Network Load Balancing.
