Which AWS service meets these requirements?
Amazon RDS for MySQL
Microsoft SQL Server on Amazon EC2
Amazon DynamoDB
Amazon Redshift
Explanations:
Amazon RDS for MySQL is a relational database service that offers automated backups and scaling but is not a NoSQL database. It is designed for structured data and requires more maintenance for scaling and management compared to NoSQL solutions.
Microsoft SQL Server on Amazon EC2 is also a relational database service. While it can be configured for high availability and durability, it does not meet NoSQL requirements and necessitates significant maintenance for server management and scaling.
Amazon DynamoDB is a fully managed NoSQL database service that provides automatic scaling, high availability, and durability. It is designed for applications requiring low-latency access to large volumes of data and requires minimal maintenance due to its serverless architecture.
Amazon Redshift is a data warehouse service optimized for analytics and reporting. It is not a NoSQL database and is intended for structured data storage and complex queries rather than the scalability and minimal maintenance required for NoSQL applications.
