QuestionQ15

Accelerate Workload Migration and Modernization

A company operates an on-premises website application that supplies real estate information to prospective renters and buyers. The website uses a Java backend and a NoSQL MongoDB database to store subscriber data.

The company must migrate the complete application to AWS while retaining a similar architecture. The application must be deployed for high availability, and the company cannot modify the application.

Which solution meets these requirements?

Explanation

Amazon DocumentDB is a fully managed MongoDB-compatible database service that can run the same application code, drivers, and tools used with MongoDB. Deploying DocumentDB instances and EC2 Auto Scaling group instances across multiple Availability Zones provides high availability without requiring a database-engine or application-code change. Amazon Aurora is a relational database, a single-AZ backend is not highly available, and DocumentDB does not use a DynamoDB-style on-demand capacity mode.
