AWS Certified Solutions Architect – Associate (SAA-C02) — Question 294

A solutions architect must design a database solution for a high-traffic ecommerce web application. The database stores customer profiles and shopping cart information. The database must support a peak load of several million requests each second and deliver responses in milliseconds. The operational overhead form an aging and scaling the database must be minimized.
Which database solution should the solutions architect recommend?

Answer options

Correct answer: B

Explanation

Amazon DynamoDB is a fully managed, serverless NoSQL database designed to scale seamlessly to handle millions of requests per second with single-digit millisecond latency, making it the perfect fit for shopping carts and customer profiles. Relational databases like Amazon RDS and Amazon Aurora introduce higher operational overhead and are not optimized for this scale of rapid key-value transactions. Amazon Redshift is a data warehouse service used for analytical queries rather than transactional, low-latency web applications.
