Introduction {#introduction}

In an effort to continually enhance the capabilities and services offered to its users, Amazon has introduced a much-requested feature. Amazon SNS FIFO topics can now support message delivery to Amazon SQS Standard queues. This breakthrough feature improves the separation between message publishers and subscribers, increasing flexibility, and providing more options to manage their messages.

What is SNS FIFO? {#snsfifo}

Amazon SNS (Simple Notification Service) encompasses fully managed pub/sub messaging and mobile push notification services on cloud platforms, which provide high throughput and reliable message delivery.

One type of SNS topic is FIFO (First-In-First-Out) which ensures that messages are delivered in the same order they were sent, promoting strict message ordering.

What is SQS Standard Queue? {#sqsstandard}

Amazon Simple Queue Service (SQS) is a scalable and highly available message queuing service for independently designed processing of messages. SQS Standard Queues facilitate at-least-once message delivery. This means every message is delivered to the recipient queue at least once, and the delivery order of the messages is not strictly maintained.

New Capability Introduction {#newcap}

The newly introduced capability – subscribing Amazon SQS Standard queues to Amazon SNS FIFO topics – enhances the flexibility of AWS users. Previously, the SNS topic type dictated the SQS queue type that subscribers needed to use. Now, users can decouple this direct-link, choosing either SQS FIFO queues for strict ordering and exactly-once delivery or SQS Standard queues for best-effort ordering and at-least-once delivery.

Benefits {#benefits}

There are several benefits to this new feature:

  1. Flexibility: Users are now afforded more choices in terms of managing messages. They can subscribe SQS Standard queues to SNS FIFO topics or continue with SQS FIFO queues.

  2. Decoupling: This new feature further decouples message publishers from subscribers, introducing a new level of abstraction and flexibility in choosing the queue type.

  3. Efficiency: The SQS Standard queues offer best-effort ordering and at-least-once delivery, ensuring every message gets delivered at least once.

How to Use {#howtouse}

Using this service starts with creating an SNS FIFO topic and an SQS Standard Queue. From here, you can subscribe your SQS Standard Queue to the SNS FIFO topic.

  1. Create SNS FIFO topic

  2. Create SQS Standard queue

  3. Subscribe SQS Standard queue to SNS FIFO topic

Best Practices {#bestpractices}

While using this new feature, it is essential to observe the following recommended practices:

  1. Monitoring: Regularly monitor your SNS FIFO topics and SQS queues to ensure messages are being delivered appropriately.

  2. Message Size Limit: Amazon provides a limit on the size of the messages. Therefore, be aware of the size of your messages to avoid failed deliveries.

  3. Securing Messages: Always apply best practices for securing messages, including encrypting messages in transit and at rest using the AWS Key Management Service.

Conclusion {#conclusion}

The launch of this new feature marks a significant stride in improving the capabilities of Amazon Web Services. This enhancement not only fosters greater flexibility but also ensures improved efficiency when delivering messages. Both Amazon SNS FIFO topics and Amazon SQS Standard queues users stand to benefit greatly from this update, further helping the decoupling of message publishers from message subscribers.

Now is the best time to dive up-to-speed with these capabilities, taking full advantage of what AWS has to offer. Don’t forget, good practices lead to desirable outputs, so stay vigilant and secure, as you organize your messaging system in AWS.
