AWS Certified Developer Associate DVA-C02 Practice Question

You are implementing a notification system for an online shopping platform hosted on AWS. The system must send emails to customers after their order has been processed. Given that the order-processing system can become backlogged during peak times, which pattern should you employ to ensure that the email notifications do not block or slow down the order-processing workflow?

  • Use a synchronous pattern where the order-processing service sends the email directly before confirming the order as complete within the same workflow.

  • Implement a hybrid pattern, sending the email synchronously for premium customers, while using an asynchronous approach for regular customers.

  • Adopt a synchronous pattern for small batches of orders, switching to an asynchronous pattern only when detecting a processing backlog.

  • Employ an asynchronous pattern with a message queue that collects notifications to be processed by a separate email-sending service independently of order processing.
