What is a Load Balancer?
A load balancer is a networking device or software application that distributes and balances the incoming traffic among the servers to provide high availability, efficient utilization of servers, and high performance.
- Load balancers are highly used in cloud computing domains, data centers, and large-scale web applications where traffic flow needs to be managed.
- The primary goal of using a load balancer is, not to overburden with huge incoming traffic which may lead to server crashes or high latency.
What is Load Balancer & How Load Balancing works?
Load Balancer is defined as a networking device or software application that distributes and balances the incoming traffic among the servers to provide high availability, efficient utilization of servers, and high performance. A load balancer works as a “traffic cop” sitting in front of your server and routing client requests across all servers. It simply distributes the set of requested operations (database write requests, cache queries) effectively across multiple servers and ensures that no single server bears too many requests.
