AWS Technical Essentials Practice

The primary purpose of AWS Elastic Load Balancing is to automatically distribute application traffic across multiple targets, such as EC2 instances, containers, and IP addresses. This ensures that no single resource is overwhelmed with too much traffic at once, which can improve responsiveness and availability of your applications. By managing load balancing effectively, it helps in achieving higher fault tolerance and scalability with your application, allowing it to handle varying levels of incoming traffic seamlessly.

Load balancing also contributes to a consistent user experience, as it enables the efficient routing of requests to the best-performing instances. This is particularly important for applications with unpredictable traffic patterns.

The other options do not align with the core functionality of Elastic Load Balancing. Increasing virtual server storage pertains to storage solutions like Amazon Elastic Block Store, enhancing database performance relates to database services such as Amazon RDS, and user access management is typically handled through AWS Identity and Access Management (IAM). Thus, those do not reflect the primary capabilities of Elastic Load Balancing.
