A company is developing a new SaaS application. The database workload is highly unpredictable, with periods of zero activity followed by sudden, massive spikes in traffic. The company wants a relational database that scales compute capacity instantly to meet demand and scales down to save costs. Which TWO database options meet these requirements? (Select TWO.)
Answer options:
A.
Amazon RDS for PostgreSQL with Auto Scaling
B.
Amazon Aurora Serverless v2 (PostgreSQL-compatible)
C.
Amazon DynamoDB On-Demand
D.
Amazon Aurora Serverless v2 (MySQL-compatible)
E.
Amazon Redshift Serverless
How to approach this question
Identify the need for a 'relational database' that scales compute 'instantly'. This is Aurora Serverless (both MySQL and PostgreSQL flavors).
Full Answer
B,D
Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It automatically starts up, shuts down, and scales capacity up or down based on your application's needs. It is available in both MySQL-compatible and PostgreSQL-compatible editions.
Common mistakes
Choosing DynamoDB, missing the 'relational database' requirement. Choosing RDS Auto Scaling, which only scales storage.
