AWS Certified Data Analytics Specialty 2021 - Hands-On! - Amazon Simple Storage Service (Amazon S3) Performance

The video tutorial covers Amazon S3's performance capabilities, including request limits and latency. It explains the concept of prefixes and how they affect request rates. The tutorial also discusses the impact of KMS encryption on S3 performance, highlighting potential throttling issues due to KMS quotas. Techniques for optimizing S3 performance, such as multipart uploads, transfer acceleration, and byte range fetches, are explored to enhance upload and download speeds.

What is the maximum number of GET requests per second per prefix in an S3 bucket?

• 3500

• 5500

• 22000

• 10000

How does KMS encryption affect S3 performance?

• It doubles the request rate.

• It reduces the number of available prefixes.

• It counts towards the KMS request quota.

• It increases the latency of requests.

What happens if you exceed the KMS request quota in a region?

• Requests are automatically rerouted to another region.

• The number of prefixes is increased.

• Requests are throttled.

• The request rate is doubled.

What is the recommended method for uploading files larger than 100 MB to S3?

• Single-part upload

• Transfer acceleration

• Byte-range fetch

• Multipart upload

What is the primary benefit of using transfer acceleration in S3?

• It reduces storage costs.

• It increases the number of prefixes.

• It speeds up data transfer by using edge locations.

• It allows for more GET requests per second.

How can byte-range fetches improve download performance from S3?

• By using edge locations

• By reducing the file size

• By parallelizing GET requests

• By increasing the number of prefixes

What is a potential use case for byte-range fetches?

• To increase the number of prefixes

• To retrieve only a portion of a file

• To upload large files

• To reduce storage costs
