Question #1080
Which of the following AWS services are serverless? (Choose two.)
AWS Elastic Beanstalk
Amazon RDS
AWS Step Functions
Amazon DynamoDB
Amazon EMR
Explanation
AWS Step Functions (C) is a serverless workflow service that coordinates AWS services without managing servers. Amazon DynamoDB (D) is a serverless NoSQL database with automatic scaling and pay-per-request pricing.
Other options are not serverless:
- A (Elastic Beanstalk) deploys apps on managed EC2 instances, requiring environment configuration.
- B (RDS) uses provisioned database instances unless using Aurora Serverless (not specified).
- E (EMR) requires managing clusters for big data processing.
Key Points:
1. Serverless = no server management, auto-scaling, pay-as-you-go.
2. Step Functions and DynamoDB fit this model.
3. Services like RDS/EMR/Elastic Beanstalk involve infrastructure management.
