AWS Technical Essentials Practice

An Elastic Load Balancer is a service designed to automatically distribute incoming application traffic across multiple targets. These targets could include Amazon EC2 instances, containers, IP addresses, or Lambda functions. The primary purpose of the Elastic Load Balancer is to enhance the availability and fault tolerance of applications. By distributing the traffic evenly, it helps ensure that no single instance becomes overwhelmed, which can lead to performance degradation or downtime.

Additionally, the Elastic Load Balancer monitors the health of the registered targets and reroutes traffic only to healthy instances, thereby providing a seamless user experience even during partial outages. This dynamic scaling capability improves both application resilience and customer satisfaction.

In contrast, other options present different concepts. One option describes a service for data storage, another refers to a framework for application development, and another pertains to network security tools, none of which align with the functionality of an Elastic Load Balancer.
