What is a primary benefit of using AWS Elastic Load Balancing?

The primary benefit of using AWS Elastic Load Balancing is its ability to distribute incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses. This load distribution enhances the availability and fault tolerance of your applications. By balancing the load, the Elastic Load Balancer ensures that no single target becomes overwhelmed with traffic, which can lead to slow response times or downtime. Moreover, it automatically adjusts to changes in traffic patterns, scaling as needed to maintain performance.

This functionality is crucial for maintaining a responsive application, especially in scenarios with fluctuating traffic levels. Load balancing also helps in enabling high availability by rerouting traffic to healthy targets when some are under maintenance or experiencing issues. Overall, this capability significantly improves the reliability and scalability of applications deployed on AWS.
