Question

An ecommerce application uses a PostgreSQL database that runs on an Amazon EC2 instance. During a monthly sales event, database usage increases and causes database connection issues for the application. The traffic is unpredictable for subsequent monthly sales events, which impacts the sales forecast. The company needs to maintain performance when there is an unpredictable increase in traffic. Which solution resolves this issue in the MOST cost-effective way?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Migrate the PostgreSQL database to Amazon Aurora Serverless v2. Aurora Serverless auto-scales database capacity and is cost-effective for variable workloads. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. This option delivers the requirement at the lowest cost.
