A company is developing a new Node.js application. The application must have a scalable NoSQL database to meet increasing demand as the popularity of the application grows. Which AWS service will meet the requirements for the database?
Amazon DynamoDB is a fully managed NoSQL database service provided by AWS. It is designed to be highly scalable and can automatically adjust its capacity to handle the changing demand of applications. DynamoDB provides consistent single-digit millisecond latency at any scale, making it well-suited for applications that require low-latency access to data even with increasing popularity and demand. Additionally, DynamoDB automatically replicates data across multiple Availability Zones to ensure high availability and durability.
C. Amazon DynamoDB
Amazon DynamoDB is a fully managed, highly scalable NoSQL database service that is well suited for building highly available, scalable, and performant applications. It is a key-value and document database that supports both document and key-value data models. It allows you to store and retrieve any amount of data, and serves any level of request traffic. DynamoDB automatically spreads the data and traffic for a table over a sufficient number of servers to handle the request capacity specified by the customer and the amount of data stored, while maintaining consistent and fast performance.
Amazon Aurora Serverless, Amazon ElastiCache and Amazon Redshift are not NoSQL databases, they are relational database service, a web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud and a data warehousing service respectively.
