Explanation
Amazon DynamoDB is the correct choice because:
-
NoSQL Database: DynamoDB is a fully managed NoSQL database service
-
High Scalability: Automatically scales to handle any amount of traffic and storage requirements
-
Durability: Provides built-in data replication across multiple Availability Zones for high durability
-
Minimal Maintenance: Fully managed service - AWS handles hardware provisioning, setup, configuration, replication, software patching, and cluster scaling
Why other options are incorrect:
-
Amazon RDS for MySQL: This is a relational database (SQL), not NoSQL
-
Microsoft SQL Server on Amazon EC2: This requires manual management and maintenance on EC2 instances
-
Amazon Redshift: This is a data warehousing service, not a NoSQL database
DynamoDB's serverless architecture and automatic scaling make it ideal for applications requiring high performance with minimal operational overhead.
