Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 596
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

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?

  • A. Migrate the PostgreSQL database to Amazon Aurora Serverless v2.
  • B. Enable auto scaling for the PostgreSQL database on the EC2 instance to accommodate increased usage.
  • C. Migrate the PostgreSQL database to Amazon RDS for PostgreSQL with a larger instance type.
  • D. Migrate the PostgreSQL database to Amazon Redshift to accommodate increased usage.

Selected Answer: A
Not B - we can auto-scale the EC2 instance, but not "the [self-managed] PostgreSQL database ON the EC2 instance" Not C - This does not mention scaling, so it would incur high cost and still it might not be able to keep up with the "unpredictable" spikes Not D - Redshift is OLAP Data Warehouse

Selected Answer: A
Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Aurora where the database automatically starts up, shuts down, and scales capacity up or down based on your application's needs. This is the least costly option for unpredictable traffic.

Selected Answer: C
A is probably more expensive than C. Aurora is serverless and fast. But nevertheless it needs DB migration service. Not sure DMS may not be free.

C is more expensive if you think the scenario where the traffic is low. You are paying for a larger hardware but not using it. That's why I think A is correct.
