SOA-C02 Question 313
Select 2Your company is hosting a web application that consists of a containerized frontend and a backend database. The application is experiencing performance issues due to resource constraints and growing operational overhead from managing the infrastructure. As a SysOps Administrator, which of the following options would best reduce your operational overhead while ensuring scalability and high availability?
- A
Migrate the backend database to Amazon RDS with Multi-AZ deployment.
- B
Deploy the frontend containers using AWS Fargate.
- C
Use Amazon EC2 instances to manually manage the frontend containers.
- D
Move the backend database to Amazon DynamoDB.
- E
Deploy the frontend containers with an Amazon EFS-mounted volume for persistent storage.
Show answer and explanation
Correct answers: A, B
Explanation
To reduce operational overhead and improve scalability, it's best to use managed services where possible. Amazon RDS with Multi-AZ deployment takes care of database management tasks like backups and failover, while AWS Fargate eliminates the need to manage infrastructure for containers. Together, these services reduce operational complexity and improve scalability and availability for the application.
- A. Correct.
Amazon RDS with Multi-AZ deployment is a managed database service that reduces operational overhead by handling backups, patching, and high availability automatically. This makes it an ideal choice for reducing the management burden on your backend database.
- B. Correct.
AWS Fargate is a serverless compute engine for containers that abstracts infrastructure management. By deploying the frontend containers using Fargate, you eliminate the need to manage EC2 instances and can scale automatically based on demand.
- C. Incorrect.
Using Amazon EC2 instances requires manual management of the instances, which increases operational overhead rather than reducing it. This is not the best choice for a scalable and managed solution.
- D. Incorrect.
Amazon DynamoDB is a NoSQL database, which may not be suitable for your existing backend database if it requires relational database features. Migrating to DynamoDB without analyzing compatibility could introduce additional complexity.
- E. Incorrect.
While Amazon EFS provides scalable file storage, it is not required for deploying frontend containers unless persistent file storage is explicitly needed. Using EFS in this scenario may introduce unnecessary complexity without clear benefits.
