AWS Technical Essentials Practice

Amazon CloudFront is a content delivery network (CDN) service that automatically manages traffic load through its globally distributed network of edge locations. This service automatically routes user requests to the nearest edge location, which helps deliver content with low latency and high transfer speeds, efficiently distributing traffic loads across the network.

CloudFront effectively handles fluctuations in traffic by using automatic scaling and load balancing features built into its infrastructure, ensuring that users receive uninterrupted service even during spikes in demand. This capability significantly reduces the need for manual management of traffic loads, allowing developers to focus on other aspects of their application instead of worrying about scaling and performance under heavy load.

In contrast, the other services mentioned have different roles: Amazon Elastic File System provides scalable file storage, Amazon Elastic Block Storage offers block storage for use with Amazon EC2 instances, and Amazon Glacier is used for archiving data at low costs. None of these services specifically focus on managing traffic loads automatically like Amazon CloudFront does.
