Hi, you used DynamoDB as an example of a weakly consistent system in the opening paragraph, but it actually supports both modes [1]. The point of confusion might come from the fact that the service described in 2007 Dynamo paper was an inspiration for DynamoDB, rather than DynamoDB itself.
Disclaimer, I work for AWS, but not on DynamoDB team.
