Load balancers enhance network resilience by distributing incoming traffic across multiple servers, ensuring no single server becomes a point of failure and optimizing resource utilization. They can automatically reroute traffic in case of server failure, thus maintaining service availability and improving overall network performance.

Example Concept: Load balancers, such as those from F5, NGINX, or AWS Elastic Load Balancing, work by monitoring the health of servers and dynamically distributing client requests based on server load, availability, and health status. This ensures that if one server goes down, traffic is seamlessly redirected to healthy servers, maintaining continuous service availability and reducing downtime.

Additional Comment:

Load balancers can operate at different OSI layers, such as Layer 4 (transport) or Layer 7 (application), providing flexibility in traffic management.
They can also enhance security by masking the internal server details from external clients.
Implementing load balancing can improve application scalability and user experience by reducing response times.
