Sns Sqs Event Driven Architecture. For example kafka, activemq, aws sns, and aws sqs. We recently faced outage with sns during some hours due to aws issue.
Different technologies can be used for sending and receiving event notifications; I can use this technique to subscribe to lots of different queues, each for its type of consumer. They’re commonly found in modern applications that has decoupled components.

You can use sqs as a destination to sns, wherein sqs queues can be used to hold the messages until the consumers are ready to process them as shown in the diagram below. For example kafka, activemq, aws sns, and aws sqs. We recently faced outage with sns during some hours due to aws issue.
Often There Is A Need To Filter These Messages Before Replicating Them To Multiple Queues.
Publisher are responsible for messaging using amazon sns. Sns and sqs became the de facto standard for all asynchronous communication in our organization. It scales automatically if the number of messages increases.;
The Broker Is Responsible For The Topic (Event) Between The Publisher And The Subscriber.
Sns distributes events to sqs: Subscribers are responsible for polling for queuing. I can use this technique to subscribe to lots of different queues, each for its type of consumer.
This Is Possible By Using Subscription Filtering To Move Event Messages From Sns To Sqs Queues.
We are currently migrating off of a legacy monolithic architecture primarily written in ruby on rails. Legacy front ends are a mix of a variety of technologies. We publish event to sns and receive via sqs.

Each subscription will filter out any irrelevant event messages. The following code is an example of an event based architecture using an sns topic per event. This replaces the traditional request/response pattern, where components actually direct commands to other components, for example when a customer.
