Build a Serverless Queue System on AWS (SQS + Lambda) | Day 3/100

Welcome to Day 3 of my #100DaysOfAWS journey! ☁️

In today's project we explore asynchronous architecture using AWS.

Instead of processing tasks immediately, we place them into a message queue where a worker processes them asynchronously. This pattern is commonly used in large-scale distributed systems to improve scalability and reliability.

We will build a system where messages are pushed into an AWS SQS queue and automatically processed by an AWS Lambda worker.

This is a common architecture used in production systems for background jobs, order processing, event pipelines, and microservices communication.

What You Will Learn Today:

Message Queues: Understanding why queues are used in distributed systems.

Amazon SQS: Creating and managing a fully managed message queue.

Lambda Workers: Automatically processing queued messages using AWS Lambda.

Event Driven Architecture: How modern applications react to events instead of synchronous requests.

Async Processing: Why background workers improve scalability.
