A company must collect user consent to a privacy agreement. The company deploys an application in six AWS Regions: two Regions in North America, two Regions in Europe, and two Regions in Asia. The application has a user base of 20 million to 30 million users.
The company needs to read and write data that is related to each user’s response. The company also must ensure that the responses are available in all six Regions.
Which solution will meet these requirements with the LOWEST latency of reads and writes?
A. Implement Amazon Elasticsearch Service (Amazon ES) in each of the six Regions.
B. Implement Amazon DocumentDB (with MongoDB compatibility) in each of the six Regions.
C. Implement Amazon DynamoDB global tables in each of the six Regions.
D. Implement Amazon ElastiCache for Redis replication groups in each of the six Regions.
