Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 173 discussion

B. Cloud front is best for content delivery. Global Accelerator is best for non-HTTP (TCP/UDP) cases and supports HTTP cases as well but with static IP (elastic IP) or anycast IP address only.

Option A is not the most cost-effective solution for this scenario. While Global Accelerator can improve global application performance, it is primarily used for accelerating TCP and UDP traffic, such as gaming and real-time applications, rather than serving static media files. Options C and D are used for caching frequently accessed data in-memory to improve application performance. However, they are not specifically designed for caching and serving media files like CloudFront, and therefore, may not provide the same cost-effectiveness and scalability for this use case. Hence, deploying an CloudFront web distribution in front of the S3 is the most cost-effective solution for delivering media files to millions of users worldwide while reducing the load on the origin.

CloudFront will cache the data in Edge Locations, offloading it partially from the source location (s3) B looks good to me.

Deploy an Amazon CloudFront web distribution in front of the S3 bucket

B) Deploy an Amazon CloudFront web distribution in front of the S3 bucket. CloudFront is the most cost-effective solution for this use case because: CloudFront can cache static assets like videos and images at edge locations closer to users. This improves performance. Serving files from the CloudFront cache reduces load on the S3 origin. CloudFront pricing is very low for data transfer and requests.

ElasticCache is for DB Cache(RDS) nor for S3

ElastiCache, enhances the performance of web applications by quickly retrieving information from fully-managed in-memory data stores. It utilizes Memcached and Redis, and manages to considerably reduce the time your applications would, otherwise, take to read data from disk-based databases. Amazon CloudFront supports dynamic content from HTTP and WebSocket protocols, which are based on the Transmission Control Protocol (TCP) protocol. Common use cases include dynamic API calls, web pages and web applications, as well as an application's static files such as audio and images. It also supports on-demand media streaming over HTTP. AWS Global Accelerator supports both User Datagram Protocol (UDP) and TCP-based protocols. It is commonly used for non-HTTP use cases, such as gaming, IoT and voice over IP. It is also good for HTTP use cases that need static IP addresses or fast regional failover

The company wants to provide the files to the users while reducing the load on the origin. Cloudfront speeds-up content delivery but I'm not sure it reduces the load on the origin. Some form of caching would cache content and deliver to users without going to the origin for each request.

To provide media files to users while reducing the load on the origin and meeting the requirements cost-effectively, the gaming company should deploy an Amazon CloudFront web distribution in front of the S3 bucket (Option B). CloudFront is a content delivery network (CDN) that speeds up the delivery of static and dynamic web content, such as images and videos, to users. By using CloudFront, the media files will be served to users from the edge location that is closest to them, resulting in faster delivery and a better user experience. CloudFront can also handle the high traffic and large number of requests expected from the millions of users, ensuring that the media files are available and accessible to users around the world.

Option B

Agreed
