You have an application storing objects in an Amazon S3 bucket. Due to massive popularity, these objects are frequently accessed from the S3 bucket. Which of the following can be used to reduce the latency of these objects?

Answer options:

A.Save objects in separate buckets in each region.
B.Use Amazon CloudFront in front of the S3 bucket.
C.Increase the number of prefixes in the S3 bucket.
D.Add random suffix to key names.

Correct Answer – B
For objects stored in the Amazon S3 bucket, Amazon CloudFront can be used to achieve a very high GET performance. Using Amazon CloudFront, users can access data locally with low latency & high throughput from the nearest POP. Also, this results in a decrease in the number of read requests directly to Amazon S3 buckets.
Option A is incorrect as although this will lower latency for users accessing from buckets within the same region. But this is not a cost-effective solution.
Option C is incorrect as although this will increase GET performance, this will not result in low latency for users.
Option D is incorrect as we need to add a prefix and not a suffix to the key names.
