A city's public information portal runs on several EC2 instances. What is the primary purpose of placing a load balancer in front of them?
Select an answer to reveal the explanation.
Short Explanation
A load balancer is the traffic cop that spreads visitors across healthy portal instances so one sick box does not take the whole site down. It is about distribution and availability—not Glacier crypto, FTP, or being a database.
Full Explanation
Elastic Load Balancing distributes incoming application traffic across multiple targets such as EC2 instances and can route only to healthy ones. That pattern improves availability and supports horizontal scale for public portals. Load balancers are not archival encryption tools, identity substitutes, or durable relational databases. CLF candidates should associate load balancers with traffic distribution and resiliency.
