A Hardware Load Balancer is a physical device that distributes network or application traffic across multiple servers. This helps ensure that no single server becomes overwhelmed, improving performance and reliability. By managing the flow of data, it enhances user experience and minimizes downtime. These devices often come with advanced features like SSL offloading and health monitoring, which check the status of servers to ensure they are functioning properly. Commonly used in data centers, a Hardware Load Balancer can support various protocols and applications, making it a crucial component in modern IT infrastructure.
