Question

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?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Use Amazon DynamoDB Streams to deliver all changes from the Accounts database to the Payments database. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. This option meets the real-time / low-latency performance requirement.
