Publisher/Subscriber Model in AWS Explained – Photo Studio Application Architecture

In this video, I walk you through the Publisher/Subscriber (Pub/Sub) model using a real-world photo studio application built on AWS. Learn how to architect scalable, loosely coupled systems by leveraging AWS services like Amazon SNS, S3, SQS, and Lambda.

We’ll cover:

- How the Pub/Sub model works and why it's perfect for event-driven architectures.
- Step-by-step breakdown of the photo processing system using AWS SNS, SQS, and Lambda functions.
- How to handle multiple tasks like image processing, thumbnail creation, and user notifications after a photo upload.
- Key benefits of this architecture, including scalability, loose coupling, and real-time processing.

By the end of this video, you'll understand how to implement a publisher/subscriber model in your own AWS architectures and enhance your cloud-based applications for better performance and flexibility.
