Question
Which of the following AWS services provides the capability to host a NoSQL database in the AWS Cloud?
A. Amazon Aurora
B. Amazon DynamoDB
C. Amazon RDS
D. Amazon Redshift
Answer
B. Amazon DynamoDB
Explanation
Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. It supports both key-value and document data models, and enables you to create tables that can store and retrieve any amount of data, and serve any level of request traffic. You can also use DynamoDB Streams to capture changes to data items in DynamoDB tables.
Amazon DynamoDB is AWS’s fully managed, serverless NoSQL database service designed to handle high-performance applications at any scale. It supports both key-value and document data models, making it ideal for use cases requiring flexibility and scalability. Here’s why DynamoDB is the correct answer:
Key Features of Amazon DynamoDB
- NoSQL Database: Unlike relational databases (e.g., Amazon RDS or Aurora), DynamoDB is a NoSQL database, meaning it does not require a predefined schema and can store unstructured or semi-structured data.
- Serverless Architecture: It eliminates the need for managing servers, patching, or scaling infrastructure, as it automatically scales based on demand.
- High Performance: DynamoDB delivers single-digit millisecond latency for read and write operations, ensuring consistent performance even under heavy workloads.
- Global Scalability: With features like global tables, DynamoDB supports multi-region replication, making it suitable for globally distributed applications.
- Integration with AWS Services: It integrates seamlessly with AWS Lambda, S3, and other services to build serverless and event-driven architectures.
Other Options Explained
A. Amazon Aurora: Aurora is a relational database service (RDS) that supports SQL-based databases like MySQL and PostgreSQL. It is not designed for NoSQL use cases1.
C. Amazon RDS: RDS is another relational database service supporting traditional SQL databases such as Oracle, SQL Server, and MariaDB. It does not provide NoSQL capabilities1.
D. Amazon Redshift: Redshift is a data warehouse solution optimized for analytics and querying large datasets using SQL. It is not suitable for operational NoSQL workloads1.
Why Choose DynamoDB for NoSQL?
DynamoDB’s design caters specifically to modern application needs where flexibility, scalability, and low-latency performance are critical. Its serverless nature reduces operational overhead, while its ability to handle unstructured data makes it an excellent choice for diverse use cases like real-time analytics, gaming leaderboards, IoT applications, and more.
For the AWS Certified Cloud Practitioner CLF-C02 exam, understanding these distinctions between database services is crucial to correctly identifying which service fits specific use cases.
