A large enterprise is seeking to enhance their system's reliability and ensure that their web application remains accessible to users, even during high traffic periods or one or more server failures. They require a solution that distributes incoming network traffic across multiple servers. Which of the following options would BEST meet their needs?
A Load balancer is designed to distribute network traffic across multiple servers. This helps to ensure that no single server bears too much demand, thereby increasing the reliability and availability of the application. Failover is a process related to standby operational mode, where the functions of a system component (like a server) are assumed by secondary system components when the primary component becomes unavailable. However, it doesn't cater to distributing traffic during normal operations. Clustering does provide high availability but does not specifically distribute network traffic like a load balancer. Replication is a process of copying data from one location to another but does not pertain to traffic distribution or immediate high availability during peak loads.
