Elastic Load Balancer (ELB) effectively manages the distribution of incoming traffic across multiple servers, which helps in balancing their workloads and enhances both the service capabilities and fault tolerance of applications. Capable of handling as many as 100 million concurrent connections, ELB meets the demands of managing large volumes of simultaneous requests. It operates in a cluster mode, ensuring continuous service availability. In cases where servers within an Availability Zone (AZ) are deemed unhealthy, ELB seamlessly redirects traffic to healthy servers located in other AZs. This functionality guarantees that applications consistently maintain adequate capacity to accommodate fluctuating workload levels. Furthermore, ELB works in conjunction with Auto Scaling, allowing for dynamic adjustments in server numbers while efficiently routing incoming traffic. With a wide array of protocols and routing algorithms at your disposal, you can tailor traffic management policies to fit your specific requirements, all while simplifying deployments. The integration of these features positions ELB as an essential tool for optimizing application performance and reliability.
