You are developing an application that would be used to upload images from users.
You need to effectively store the images and also the name of the user who uploaded the image.

This is also mentioned in the AWS Documentation.
As mentioned above, you can also take advantage of Amazon Simple Storage Service (Amazon S3) to store large attribute values that cannot fit in a DynamoDB item.
You can store them as objects in Amazon S3 and then store the object identifier in your DynamoDB item.
Options A and C are incorrect since it should be the other way around in terms of storage.
For more information on this use case, please refer to the below URL-
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-use-s3-too.htmlThe best approach for storing images and user information depends on the specific requirements of the application, but two possible solutions are:
Amazon S3 (Simple Storage Service) is an object storage service that provides highly scalable and durable storage for any type of data, including images. S3 is designed for storing and retrieving large files, and provides a simple web services interface that can be used to upload and download objects from anywhere in the world.
To store user information such as the name of the user who uploaded the image, a NoSQL database like Amazon DynamoDB can be used. DynamoDB is a fully managed NoSQL database that provides fast and predictable performance with seamless scalability. It can be used to store and retrieve any amount of data, and supports key-value and document data models.
By storing the images in S3 and the user information in DynamoDB, the application can benefit from the scalability and performance of both services. S3 can handle the storage and retrieval of large files, while DynamoDB can provide fast and efficient access to user information.
Alternatively, both the images and the user information can be stored in S3 using object metadata to store the name of the user who uploaded the image. Object metadata is a set of name-value pairs that are associated with an S3 object. Metadata can be used to store any additional information about the object, such as the name of the user who uploaded it.
By storing both the images and user information in S3, the application can benefit from the simplicity and scalability of S3. However, retrieving user information may require additional processing of the object metadata, which may not be as efficient as using a dedicated database like DynamoDB.
Overall, the best approach depends on the specific requirements of the application, such as the amount and type of data being stored, the expected traffic, and the need for efficient access to user information.
