Key characteristics of Load Balancers
- Traffic Distribution: Load balancers evenly distribute incoming requests among multiple servers, preventing any single server from being overloaded.
- High Availability: By distributing traffic across multiple servers, load balancers enhance the availability and reliability of applications. If one server fails, the load balancer redirects traffic to healthy servers.
- Scalability: Load balancers facilitate horizontal scaling by easily accommodating new servers or resources to handle increasing traffic demands.
- Optimization: Load balancers optimize resource utilization, ensuring efficient use of server capacity and preventing bottlenecks.
- Health Monitoring: Load balancers often monitor the health of servers, directing traffic away from servers experiencing issues or downtime.
- SSL Termination: Some load balancers can handle SSL/TLS encryption and decryption, offloading this resource-intensive task from servers.
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.
