AWS S3 or DynamoDB

Question

I can't decide what to choose between AWS Dynamo DB or AWS S3. I have a use case in which I need to fetch multiple items from the data source and update the items and put back to the data source. I tried to search and find that we can't perform multiple gets in S3.

Any small help for this small question will be appreciated, thanks!

Answer 1

I have used both Dynamodb and S3. It purely depends on your application and type of data, if you're going for a real. Latency is good on DynamoDB as compare to s3 and you can update data based on your key. If you are going to update images or some kind of files you can use s3 and you can save some money with s3.
