Ensure Optimal Performance
Question
Your company is planning to use the Simple Storage Service to store objects that will be accessed by users.
There is speculation that there would be roughly 6000 GET requests per second.

A. B. C. D.Answer - A and B.
Storing your static content with S3 provides a lot of advantages.
But to help optimize your application's performance and security while effectively managing cost, we recommend that you also set up Amazon CloudFront to work with your S3 bucket to serve and protect the content.
CloudFront is a content delivery network (CDN) service that delivers static and dynamic web content, video streams, and APIs around the world, securely and at scale.
S3 Transfer Acceleration improves transfer performance by routing uploads and downloads through Amazon CloudFront's globally distributed Edge Locations and over AWS backbone networks, and by using network protocol optimizations.
Option C is incorrect as it can only be used to prevent the accidental deletion of objects.
Option D is incorrect as S3 Cross-region replication can be used to improve latency (across regions) as well as disaster recovery.
The question does not give any region-specific details or any need for bucket migration or high availability of bucket and therefore it is an inappropriate option.

A. Use a CloudFront distribution in front of the S3 bucket: Using CloudFront, a content delivery network (CDN) service, in front of the S3 bucket can help to improve performance by caching frequently accessed objects in edge locations around the world. This will reduce the latency and improve the overall user experience.
B. Enable S3 Transfer Acceleration: S3 Transfer Acceleration uses Amazon CloudFront's globally distributed edge locations to accelerate transfers over the public internet to S3 buckets. This service can help to improve the speed of uploading and downloading objects from S3, especially when the objects are large or being accessed from across regions.
C. Enable versioning for the objects: Enabling versioning for objects in an S3 bucket allows you to keep multiple versions of the same object. This can be useful for backup and recovery purposes. Versioning can also help to ensure that data is not lost or corrupted accidentally.
D. Enable Cross Region Replication for the bucket: Cross Region Replication allows you to replicate objects from one S3 bucket to another in a different region. This can be useful for data protection, compliance, and disaster recovery. By replicating data to a different region, you can ensure that the data is available even if the original region experiences an outage.
In this scenario, option A and B can be used to ensure optimal performance. Using CloudFront will help to improve the latency and overall user experience by caching frequently accessed objects, and enabling S3 Transfer Acceleration can improve the speed of uploading and downloading objects from S3. However, options C and D are not directly related to improving performance in this scenario.
Therefore, the correct answers are A and B.
