Load balancer acts as a “traffic cop” who sits in front of your server and routes client requests on all servers that are able to fulfill these requests in a way that maximizes speed and capacity utilization and ensures that no one server is working too hard, which can reduce the performance. If one server goes down, the load balancer directs traffic to the remaining online servers. When a new server is added to the server group, the load balancer automatically starts sending requests to it.
Regardless of whether it’s hardware or software, or what algorithm it uses, load balancers disburse traffic to different web servers in a collection of resources to ensure that no one server is overworked and then unreliable. Load balancers effectively minimize server response time and maximize throughput.
Indeed, the role of the load balancer is sometimes likened to the role of the traffic police, because it is intended to systematically route requests to the right location at certain times, thereby preventing expensive traffic jams and unexpected incidents. Load balancers must ultimately provide the performance and security needed to maintain a complex IT environment, as well as the complicated workflows that occur within it.
Load balancing is the most scalable methodology for handling many requests from modern multi-device multi-device workflows. Along with a platform that allows unlimited access to various applications, files and desktops in today’s digital workspace, load balancing supports a more consistent and reliable end-user experience for employees.
