D. Amazon Simple Queue Service (Amazon SQS) Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS allows you to send, store, and receive messages between application components, which aligns with the company's requirement to send, store, and receive messages between application components. Additionally, SQS provides a FIFO (First-In-First-Out) queue that guarantees that messages are processed in the order they are sent, which aligns with the company's requirement to process messages in FIFO order. SQS is a highly available and scalable service that can handle millions of messages per second, making it a suitable option for the company's application.

hangN Highly Voted 2 years, 3 months ago You can now use Amazon Simple Notification Service (Amazon SNS) FIFO topics, in combination with Amazon Simple Queue Service (Amazon SQS) FIFO queues, to build applications that require messages to be sent and processed in a strict sequence and without duplicates. SNS FIFO is intended for customer use cases where it is critical to maintain the consistency in processing messages across multiple independent services in a strictly ordered manner. https://aws.amazon.com/about-aws/whats-new/2020/10/amazon-sns-introduces-fifo-topics-with-strict-ordering-and-deduplication-of-messages/ So, it should be SNS FIFO or SQS. I chose Simple Queue Service for the answer.

D. Amazon Simple Queue Service (Amazon SQS) "Does Amazon SQS provide message ordering? Yes. FIFO (first-in-first-out) queues preserve the exact order in which messages are sent and received. If you use a FIFO queue, you don't have to place sequencing information in your messages. For more information, see FIFO Queue Logic in the Amazon SQS Developer Guide." https://aws.amazon.com/sqs/faqs/#:~:text=Does%20Amazon%20SQS%20provide,SQS%20Developer%20Guide.

D is the answer.
