A. B. C. D.Correct Answer - B.
The use cases mentioned in the scenario have unstructured data in common.
Therefore, the most appropriate attribute of Amazon DynamoDB is its flexible data model and single-digit millisecond latency.
https://aws.amazon.com/blogs/database/how-to-determine-if-amazon-dynamodb-is-appropriate-for-your-needs-and-then-plan-your-migration/Option A is INCORRECT because being fully-managed and having no infrastructure overheads do not distinguish DynamoDB as the best-suited solution for the given use cases.
Option C is INCORRECT because the aspect of fault-tolerance, disaster recovery and high availability is also present in Amazon Relational Databases (RDS)
This feature does not distinguish the service in accordance with the described use cases.
Option D is INCORRECT because this attribute of DynamoDB does not fully justify its exclusive choice over other instances when considered for implementation in the use cases mentioned in the question.
Amazon DynamoDB is a fully managed, high-performance NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB is best suited for mobile, Internet of Things (IoT), and gaming applications for several reasons, including:
A. Fully-Managed Database Instance with No Infrastructure Overheads: DynamoDB is a fully managed service, which means that AWS handles the heavy lifting of setting up, scaling, and maintaining the database infrastructure. This frees up application developers from the burden of managing database hardware, software, and configurations, allowing them to focus on building their applications.
B. Flexible Data Model and Single-Digit Millisecond Latency: DynamoDB offers a flexible data model that can support various data types and data structures. The service also provides single-digit millisecond latency for both read and write operations, which makes it ideal for real-time applications that require fast and responsive data access.
C. Geographically Diverse Data Centers: When deploying an application on DynamoDB, users can select the region that is closest to their customers to reduce latency and improve performance. DynamoDB instances operate across multiple Availability Zones within an AWS Region to provide high availability and data durability. This means that the data stored in DynamoDB is automatically replicated across multiple geographically diverse data centers.
D. Support for Eventually and Strongly Consistent Reads: DynamoDB offers two types of reads: eventually consistent reads and strongly consistent reads. Eventually consistent reads provide the most up-to-date data most of the time, while strongly consistent reads provide the most up-to-date data all the time. Developers can choose the type of read that best suits their application's needs. This feature is particularly useful for mobile and IoT applications that may experience intermittent network connectivity and may require the ability to read stale data in some cases.
In summary, Amazon DynamoDB is best suited for mobile, Internet of Things (IoT), and gaming applications due to its fully managed database instance with no infrastructure overheads, flexible data model, single-digit millisecond latency, geographically diverse data centers, and support for eventually and strongly consistent reads.
