Developing Serverless Applications with AWS Lambda, SQS, and SNS

Building scalable, resilient cloud applications requires moving away from monolithic architectures and embracing decoupled, serverless microservices. Using AWS Lambda, SQS, and SNS, you can design systems that handle massive traffic spikes without managing a single server. This text-based course guides you from serverless fundamentals to deploying highly reliable event-driven architectures. You will understand how to connect serverless functions with message queues and notification topics, ensuring your applications are modular, fault-tolerant, and easy to maintain. What you'll learn: - Understand foundational serverless concepts, cloud event models, and the core benefits of asynchronous messaging. - Configure AWS Lambda functions to execute code in response to system events and API calls. - Implement message queues with SQS to decouple services and buffer workloads effectively. - Design publish-subscribe patterns using SNS to broadcast notifications to multiple subscribers simultaneously. - Apply modern serverless monitoring, structured logging, and basic infrastructure-as-code principles for easier deployment. - Troubleshoot common integration issues using dead-letter queues and error-handling strategies. You will start by exploring essential terminology and serverless architecture patterns before moving on to step-by-step written guides that show you how to integrate these services. Through clear code snippets and architectural explanations, you will learn how to build and debug a complete event-driven workflow. This course is designed for beginner developers, cloud enthusiasts, and system architects who want to learn serverless development on AWS. No prior cloud engineering experience is required, though a basic familiarity with programming concepts will help you get the most out of the material.
