Is the Elastic Load Balancer service chargeable?

The Elastic Load Balancer (ELB) service incurs costs based on usage, making it a chargeable service. AWS charges for ELB based on the amount of traffic processed and the number of load balancers running. This pricing model includes charges for data processed by the load balancer, as well as costs associated with the load balancer's active hour usage.

Understanding that ELB is designed to distribute incoming application traffic across multiple targets, such as Amazon EC2 instances, it plays a crucial role in optimizing resource utilization, enhancing availability, and achieving greater fault tolerance in applications. Consequently, the costs associated with ELB reflect its ability to efficiently manage and balance traffic, which is a necessary function for running web applications and services in a scalable and reliable manner.

The other options suggest misconceptions about the service's pricing structure. ELB is not a free service, nor does it only incur charges during peak hours, as costs are cumulative based on continual usage. While it’s true that you would be charged for underlying resources like EC2 instances, this does not negate the independent pricing structure of the ELB service itself.
