    Load Balancing

    A load balancer is a piece of hardware (or virtual hardware) that acts like a reverse proxy to distribute network and/or application traffic across different servers. A load balancer is used to improve the concurrent user capacity and overall reliability of applications. A load balancer helps to improve these by distributing the workload across multiple servers, decreasing the overall burden placed on each server.

    Physical load balancing appliances are similar in appearance to routers. They are connected to your network infrastructure in the same manner as a router or another server. In contrast, virtual load balancing hardware is a program that emulates the addition of a new hardware load balancing solution. These virtual load balancers work in a manner similar to a virtual server or a virtual computer on your network. They act as a physical load balancer and distribute requests accordingly, saving you space and offering greater flexibility than many hardware balancers.
