My answer is AE too. But my question is can DynamoDB and Elasticache be used together? Are there many scenarios of using them both in the same application?

it is asking about the use case of each DB C. Amazon Neptune It is not relevant, AWS Neptune is Graph database D. Amazon Elasticsearch Service it is not a use case, ES is using for log store/search/metric/config info/document list/ etc E. Amazon ElastiCache It is used to cache the data for faster query (read) performance, usually using before a database A, B is my choice. Redshift is dataware house, but can be used as a data lake as high concurrent write.

AE would make sense if not this part: "needs to select a platform that is highly scalable for a large number of concurrent writes". I think AD is a better choice here.

A. Amazon DynamoDB -- ideal for this requirement B. Amazon Redshift -- Wrong choice C. Amazon Neptune -- Not a requirement to have graph database D. Amazon Elasticsearch Service -- Not requirement for ElasticSearch E. Amazon ElastiCache -- The requirement is write intensive.. Not sure how Elasticache can help. A,E seem to be the best choice.

My ans is A and D. Why not E, E is store data in memory and normally we use it as a buffer server but not the server to store the data. D, Amazon Elasticsearch is Highly scalable.

Amazon OpenSearch Service (successor to Amazon Elasticsearch Service) makes it easy for you to perform interactive log analytics, real-time application monitoring, website search, and more. Seems like an overkill for a 2-3 multiple question. I vote for AE
