Which Amazon service is best for delivering content with low latency?

• A. Amazon S3
• B. Amazon CloudFront
• C. Amazon RDS
• D. Amazon Lambda

Answer: (B)

Amazon CloudFront is the most suitable service for delivering content with low latency due to its design as a content delivery network (CDN). CloudFront caches copies of your content at various edge locations around the world, which are strategically placed closer to end-users. This geographic distribution reduces the distance data must travel, significantly improving response times and minimizing latency. When a user requests content, CloudFront can serve it from the nearest edge location. This retrieval process is much faster than retrieving content from a central server or a data center that may be located far away from the user, thereby achieving low-latency delivery. In addition, CloudFront optimizes file delivery through various mechanisms such as dynamic content delivery, forming multiple connections, and effectively managing high volumes of requests. In contrast, while Amazon S3 is a highly durable storage solution, it does not inherently provide the low-latency delivery advantages that CloudFront does when serving content. Amazon RDS is a relational database service that manages and scales databases, but it is primarily focused on data storage and retrieval rather than content delivery. Amazon Lambda, a serverless compute service, processes and executes code in response to events but does not specifically address the needs for low-latency content delivery.
