For anyone building microservices or needing a reliable communication protocol between components (e.g., backend services), AWS SNS and SQS are powerful tools that enable seamless and efficient messaging.
Amazon Simple Notification Service (SNS) and Simple Queue Service (SQS) are essential for implementing decoupled and scalable architectures. SNS operates as a pub/sub messaging service, allowing you to broadcast messages to multiple subscribers in real time. On the other hand, SQS acts as a message queuing service, enabling async communication by decoupling producers and consumers. Together, they provide a robust solution for building reliable, event-driven systems(more on this benefits in a bit).
A bit on SNS
basically SNS broadcast a message to has many components subscribed to it in real-time. SNS is a really cool service because it can broadcast a variety of messages like HTTP/S, email, SMS and even trigger lamdas. Some common uses are:
- Sending alerts and notifications to system administrators or end-users.
- Broadcasting updates to multiple systems in an event-driven architecture.
A bit on SQS
basically SQS is a fully managed message queuing service that enables decoupling between the components of distributed systems I.e Messages are placed into a queue and consumed by workers at their own pace. These workers can me lamdas for examples
combining both worlds
By combining SNS and SQS, you can build a powerful messaging architecture that combines the benefits of both systems. For example, you can use SNS to broadcast messages to multiple SQS queues, which act as buffers for downstream processing. This pattern is called SNS Fan-out.
How SNS Fan-out Works:
- Publish a Message to SNS: An event triggers an SNS topic.
- Distribute to SQS Queues: Each SQS queue subscribed to the SNS topic receives a copy of the message.
- Process Messages Independently: Each queue is processed independently by its respective consumers.
