Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 3 discussion

i WILL Go with A.

"S3TA Use Cases: Mobile & web application uploads and downloads - Many customers develop mobile or web applications that feature file uploads to S3. When these applications have users that are far from the destination S3 bucket, uploads and downloads may be slow. S3TA can help speed up these long-distance transfers to provide users a better experience." from https://aws.amazon.com/s3/transfer-acceleration/ Hence, I would say that this is the correct answer, as the question asks about minimizing latency and increasing performance. In response to some of the comment about scalability, S3 is scalable by nature

(C & D) are eliminated bc the scenario doesn't require a compute resource & EC2 is not cost-effective. The scenario requires a storage solution like S3 to minimize upload and download latency and maximize performance for users from different geographic regions of the world. This situation is made for S3 Transfer Acceleration. (B) is eliminated. S3 Transfer Acceleration (A) -Amazon S3 Transfer Acceleration enables fast and easy data transfer into an S3 bucket by taking advantage of Amazon CloudFront and AWS edge locations, which are globally distributed. This data is then routed to Amazon S3 over an optimized network path. -Use Transfer Acceleration when: • You have customers all around the world who upload to a centralized bucket • You transfer GBs or TBs of data across continents on a regular basis • You underutilize the available bandwidth when you upload files to Amazon S3 over the internet

Hi from what I see and I have read has to be scalable, cost effective, low latency, S3TA is not that cost effective... but EC2 auto scalling + CF is, also you got lots of security, CG also delivers content globally to edge locations. I was skeptical about C but I would go with this. Option A is great as well HPC/ low latency... but will cost you more. CF delivers static and dynamic application data as well. I think both are good solutions but again all companies considers cost.

The answer is C. When you hear people can access from different geographical regions, the first thing you need is cloud front.

Answer - A

Answer is C. Using Amazon EC2 with Auto Scaling and Amazon CloudFront is the most suitable option. Amazon CloudFront is a globally distributed CDN that caches content at edge locations around the world. It reduces latency by serving content from the nearest edge location to the user, improving both upload and download speeds. Auto Scaling with EC2 instances ensures scalability to handle varying loads.

This is a typical use case for TA, as listed by AWS here: https://aws.amazon.com/s3/transfer-acceleration/ "Mobile & web application uploads and downloads Many customers develop mobile or web applications that feature file uploads to S3. When these applications have users that are far from the destination S3 bucket, uploads and downloads may be slow. S3TA can help speed up these long-distance transfers to provide users a better experience. " So Answer must be A. There is nothing in option C that can help with huge upload or download which is the primary use case in the question.

We trust Auto Scaling to dynamically adjust the server based on demand and Cloudfront for Content delivery network. Those voting in favour of A, Transfer Acceleration is a good choice for optimizing large file uploads but wont address latency issues.

I'll go with C. Requirement is to create a "scalable" cluster. So, we have to go for EC2 auto scaling. Next is - users from different location in globe want to access it with better performance. That is where cloud front will help.

Correct answer is 'C'

Answer is C... as it say it should be cost effective + scalable transfer acceleration cause some extra cost

answer is A : because S3TA uses cloudfront to reduce the latency. S3TA improves transfer performance by routing traffic through Amazon CloudFront’s globally distributed Edge Locations and over AWS backbone networks, and by using network protocol optimizations. https://aws.amazon.com/s3/transfer-acceleration/

Pourquoi utiliser Transfer Acceleration ? Vous pouvez utiliser Transfer Acceleration sur un compartiment pour des raisons diverses : Vos clients effectuent les chargements vers un compartiment centralisé à partir du monde entier. Vous transférez régulièrement de plusieurs gigaoctets à plusieurs téraoctets de données d'un continent à l'autre. Vous ne pouvez pas utiliser toute la bande passante disponible sur Internet lors du chargement vers Amazon S3.

Answer: C "Amazon S3 static websites support only HTTP endpoints. Amazon CloudFront uses the durable storage of Amazon S3 while providing additional security headers, such as HTTPS." https://docs.aws.amazon.com/AmazonS3/latest/userguide/HostingWebsiteOnS3Setup.html

Amazon S3 with Transfer Acceleration uses Amazon CloudFront's globally distributed edge locations to accelerate uploads to S3 over the public internet. However, it is important to note that Amazon S3 with Transfer Acceleration is primarily designed to optimize data transfers over long distances, across geographic regions or continents, and to improve throughput for larger objects. It may not be the most cost-effective solution for small object sizes and frequent data transfers between nearby regions.

I think keyword is scalable..HAs to have ASG and Cloud front foe cache
