Topic 1 Question 452
A company needs to modernize an application and migrate the application to AWS. The application stores user profile data as text in a single table in an on-premises MySQL database.
After the modernization, users will use the application to upload video files that are up to 4 GB in size. Other users must be able to download the video files from the application. The company needs a video storage solution that provides rapid scaling. The solution must not affect application performance.
Which solution will meet these requirements?
Migrate the database to Amazon Aurora PostgreSQL by using AWS Database Migration Service (AWS DMS). Store the videos as base64-encoded strings in a TEXT column in the database.
Migrate the database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS) with the AWS Schema Conversion Tool (AWS SCT). Store the videos as objects in Amazon S3. Store the S3 key in the corresponding DynamoDB item.
Migrate the database to Amazon Keyspaces (for Apache Cassandra) by using AWS Database Migration Service (AWS DMS) with the AWS Schema Conversion Tool (AWS SCT). Store the videos as objects in Amazon S3. Store the S3 object identifier in the corresponding Amazon Keyspaces entry.

Storing the videos as objects in S3 is scalable and cost-effective for storing large files. DynamoDB can store video metadata (including the S3 key), allowing for efficient retrieval and management of the videos.

B 4GB in file size would be S3 Amazon Keyspaces (for Apache Cassandra) is not relevant at all
