SOA-C02 Question 316
Select 2Your company is planning to deploy a new application that requires a highly scalable backend database, containerized microservices, and shared storage for processing large media files. As a SysOps Administrator, you need to recommend AWS managed services to minimize operational overhead. Which combination of AWS managed services is most appropriate for this use case?
- A
Amazon RDS for the database, AWS Fargate for running containers, and Amazon EFS for shared storage
- B
Amazon EC2 for running the database and containers, and Amazon S3 for shared storage
- C
Amazon DynamoDB for the database, AWS Lambda for running containers, and Amazon S3 for shared storage
- D
Amazon Aurora for the database, AWS Fargate for running containers, and Amazon EFS for shared storage
- E
Amazon ElastiCache for the database, Amazon ECS for running containers, and Amazon S3 for shared storage
Show answer and explanation
Correct answers: A, D
Explanation
To reduce operational overhead, the best approach is to leverage managed services provided by AWS. Amazon RDS and Amazon Aurora are fully managed relational database solutions, AWS Fargate allows you to run containers without managing servers, and Amazon EFS provides file-level shared storage, which is ideal for applications processing large files. These services minimize the need for manual infrastructure management while providing scalability and reliability. Options involving EC2 or services not designed for the specific use case (e.g., DynamoDB for relational requirements or ElastiCache as a database) are not suitable.
- A. Correct.
This is a correct option. Amazon RDS provides a managed relational database solution, AWS Fargate is a serverless service for running containers, and Amazon EFS provides shared storage for applications requiring file-based access.
- B. Incorrect.
This option is incorrect because using Amazon EC2 for the database and containers increases operational overhead compared to managed services. Additionally, Amazon S3 is an object storage service, not suitable for shared storage requiring file-level access.
- C. Incorrect.
This option is incorrect because Amazon DynamoDB is a NoSQL database, which may not meet the requirements for a relational database backend. Also, AWS Lambda is not designed to run containerized applications continuously.
- D. Correct.
This is a correct option. Amazon Aurora is a managed relational database service with high scalability, AWS Fargate is an excellent choice for running containerized applications without managing servers, and Amazon EFS provides shared file storage for processing large media files.
- E. Incorrect.
This option is incorrect because Amazon ElastiCache is a caching service, not a database solution. Additionally, using Amazon ECS with EC2 instances for running containers requires managing the underlying infrastructure, which increases operational overhead.
