A company is required to collect user consent to a privacy agreement. An application is deployed in six AWS Regions with two in North America, two in Europe, and two in Asia with a user base of 20-30 million users. The company needs to read and write data related to each user's response, and ensure the responses are available in all six Regions.

What solution will satisfy these requirements while MINIMIZING latency?

Ah, the age-old debate: DynamoDB vs. Redis. You both make good points. I think it really comes down to the specific data access patterns and requirements. If the company needs to prioritize fast reads over writes, then yeah, the Redis option could be a better fit. But either way, the global distribution is key, so those are the two best options in my opinion.

Hmm, I'm not so sure about DynamoDB. While it's a great choice for global data distribution, I'm wondering if the write performance might be a bottleneck with that many users. Maybe something more optimized for reads, like Redis, could work better? Option D with ElastiCache Redis replication groups might be worth considering.

Yeah, I agree that DynamoDB global tables seem like the way to go here. The automatic replication across Regions should meet the need for low latency and data availability. Plus, DynamoDB is designed to handle massive amounts of traffic, so the 20-30 million users won't be an issue.

And with DynamoDB's ability to handle large amounts of traffic, the user base should not be a problem.

That's what I was thinking too. DynamoDB global tables seem like the best fit for this scenario.

C) Implement Amazon DynamoDB global tables in each of the six Regions.

This is a tricky question. The key requirements here are low latency and global data availability. I'm thinking that option C, Amazon DynamoDB global tables, might be the best solution. DynamoDB can handle the high user volume and the global tables feature will ensure the data is accessible across all six Regions.
