S3 Quiz
A company has an application that uses the S3 bucket as its data layer. As per the monitoring on the S3 bucket, it can be seen that the number of GET requests is 400 requests per second. The IT Operations team receives service requests about users getting HTTP 500 or 503 errors while accessing the application. What can be done to resolve these errors? Choose 2 answers from the options given below.
A. Add a CloudFront distribution in front of the bucket.
B. Add randomness to the key names.
C. Add an ELB in front of the S3 bucket.
D. Enable Versioning for the S3 bucket.
A. & B.
AWS Documentation mentions the following:
When your workload is sending mostly GET requests, you can add randomness to key names. In addition, you can integrate Amazon CloudFront with Amazon S3 to distribute content to your users with low latency and a high data transfer rate.
Note: S3 can now scale to high request rates. Your application can achieve at least 3,500 PUT/POST/DELETE and 5,500 GET requests per second per prefix in a bucket.
However the AWS exam questions are not yet updated reflecting these changes in the questions. Hence the answer for this question is based on the initial request rate performance.
