A city 311 portal runs on several EC2 web servers. Staff want traffic spread across healthy targets and unhealthy ones taken out of rotation. Which AWS service purpose fits that need at Cloud Practitioner depth?
Select an answer to reveal the explanation.
Short Explanation
Picture a traffic cop at a busy intersection sending cars only to open lanes. An Application or Network Load Balancer does that for web requests—it spreads load and stops sending traffic to sick targets. RDS stores data, S3 stores objects, and Snowball moves bulk data offline—none of those are the front-door traffic spreader.
Full Explanation
Elastic Load Balancing distributes incoming application traffic across multiple targets and performs health checks so unhealthy targets stop receiving traffic. Application Load Balancers and Network Load Balancers serve that purpose for HTTP/HTTPS or TCP/UDP workloads at Cloud Practitioner recognition depth. Amazon RDS is a managed relational database, Amazon S3 is object storage, and AWS Snowball is a data-transfer appliance; none replace a load balancer for spreading web requests.
