Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 466 discussion

In a move toward using microservices, a company’s management team has asked all development teams to build their services so that API requests depend only on that service’s data store. One team is building a Payments service which has its own database; the service needs data that originates in the Accounts database. Both are using Amazon DynamoDB.

What approach will result in the simplest, decoupled, and reliable method to get near-real time updates from the Accounts database?

  • A. Use AWS Glue to perform frequent ETL updates from the Accounts database to the Payments database.
  • B. Use Amazon ElastiCache in Payments, with the cache updated by triggers in the Accounts database.
  • C. Use Amazon Data Firehose to deliver all changes from the Accounts database to the Payments database.
  • D. Use Amazon DynamoDB Streams to deliver all changes from the Accounts database to the Payments database.
