“Introducing Amazon Demand” could be used to announce a new good or service that Amazon is offering. It’s difficult to say with certainty what “Amazon Demand” might be without more information, but it could possibly be a platform or tool used by companies to control their inventory and sales on Amazon’s marketplace.
It’s crucial to specify how services exchange information when creating a distributed software architecture. By decoupling components and streamlining scalability, for instance, the use of asynchronous communication lessens the impact of modifications and facilitates the introduction of new features.
By using message queues, messages are kept in the queue until a consumer process and delete them. SQS offers a fully managed message queuing solution on Amazon with no additional administrative burden.
A message posted to a subject is sent to all topic subscribers when using pub/sub messaging. A fully managed pub/sub messaging service on AWS, Amazon Simple Notification Service (Amazon SNS), allows for the delivery of messages to a sizable subscriber base. Each subscriber has the option of setting a filter policy to only receive the communications that interest them.

Welcome to SNS FIFO Topics: Amazon Demand
With the release of SNS FIFO topics, we are introducing similar capabilities for pub/sub messaging today, offering strict message ordering and deduplicated message delivery to one or more subscribers.
Like FIFO queues, FIFO topics control ordering and deduplication:
Ordering: When publishing a message to a FIFO topic, you configure a message group by including a message group ID. All messages are sent and delivered in the order they arrive for each message group ID. For instance, you can publish these messages to the subject using the client’s account number as the message group ID to guarantee that communications pertaining to the same customer are delivered in the correct sequence. The number of message groups with FIFO subjects is unrestricted.
The message group ID does not need to be specified in advance; any value will do. Use the same message group ID for all messages if there is no logical way to distinguish them, and you will have just one group of ordered messages. Any subscribed FIFO queue receives the message group ID.
Deduplication: Sometimes client applications and distributed systems (like SNS) produce duplicate messages. By either enabling content-based deduplication on the topic or including a deduplication ID in your published messages, you can prevent repeated message delivery from the topic. With message content-based deduplication, SNS generates the message deduplication ID from the message’s body using an SHA-256 hash.
Following a message with a particular.
When the timing of actions and events is crucial or when duplicates cannot be tolerated, you can implement applications more easily by combining FIFO topics and queues. For instance, to handle accounting procedures and inventory changes, or to asynchronously carry out instructions from a client device. FIFO queues can employ message filtering in FIFO topics to only receive a portion of the messages broadcast to the topic rather than all of them.
How to Utilize FIFO Topics on SNS:
When you get changes that need to be processed sequentially, FIFO topics can be useful. I could, for instance, utilize a FIFO topic to get updates from a program where my clients can edit their account profiles.
Following that, I subscribe an SQS FIFO queue to the FIFO topic and use the queue as a trigger for a Lambda function to apply the account updates to an Amazon DynamoDB database that is utilized by my customer management system and needs to be maintained up to date.
It is simpler to implement new functionality while having little impact on current applications thanks to the decoupling that the FIFO topic introduces. For instance, I installed a new loyalty application that stores data in a relational database managed by Amazon Aurora to reward my loyal customers with further promotions.
I may build a new Lambda function that accepts customer changes in the same order that they are generated and applies them to the loyalty database in order to keep the customer information contained in the loyalty database in sync with my other apps. By doing this, I can integrate the new Loyalty app without having to modify the code or settings of existing programs.
