AWS Certified Solutions Architect – Professional — Question 347

Someone has recommended a new client to you and you know he is into online gaming and you are almost certain he will want to set up an online gaming site which will require a database service that provides fast and predictable performance with seamless scalability.
Which of the following AWS databases would be best suited to an online gaming site?

Answer options

• A. Amazon SimpleDB
• B. Amazon DynamoDB
• C. Amazon Redshift
• D. Amazon ElastiCache

Correct answer: B

Explanation

Amazon DynamoDB is a fully managed NoSQL database service designed to deliver single-digit millisecond latency and seamless scalability, making it the ideal choice for gaming workloads. Amazon Redshift is optimized for analytical warehousing, Amazon SimpleDB has severe storage limitations, and Amazon ElastiCache is primarily an in-memory caching layer rather than a primary database for persistent storage.
