The load balancer distributes incoming application traffic across multiple targets, such as EC2 instances, in multiple availability zones. "This increases the fault tolerance of your application." elastic load balancing detects unhealthy targets and routes traffic only to healthy targets.

The load balancer servers as a single point of contact for clients. this increases the availability of your application. you can add and remove targets from your load balancer as your needs change , without disrupting the overall flow of request to your application. elastic load balancing scales your load balancer as traffic to your application changes over time.elastic load balancing can scale to the vast majority of workloads automatically.

You can configure health checks, which are used to monitor the health of the registered targets so that the load balancer can send requests only to the healthy targets.
