Building Serverless Microservices with Node.js and AWS

Building backend applications that scale to millions of users often feels daunting when you have to manage complex server infrastructure. Serverless architecture changes everything by letting you focus entirely on writing code while the cloud handles the scaling, provisioning, and maintenance. This text-based course guides you through the core concepts of serverless development, empowering you to build highly available microservices. You will transition from writing basic cloud functions to designing robust, event-driven backend systems that are highly cost-effective and performant. What you'll learn: - Understand the foundational architecture of serverless computing and cloud resources. - Configure and deploy cloud functions using the Serverless Framework and AWS Lambda. - Build REST APIs and CRUD endpoints integrated with API Gateway and DynamoDB. - Implement asynchronous communication between microservices using message queues. - Apply modern security practices, including IAM least-privilege access control. - Write unit tests for serverless functions and set up basic cloud observability. You will start with fundamental serverless definitions and configuration basics before moving step-by-step through database integration, event-driven patterns, and deployment workflows. Each concept is reinforced with clear written explanations, modular code snippets, and practical architectural scenarios. This course is designed for beginner backend developers, JavaScript enthusiasts, and clean-code advocates who want to transition to cloud-native development without needing prior cloud infrastructure experience.
