Serverless GraphQL on AWS with Lambda and AppSync

Modern application development demands fast, scalable, and cost-effective APIs. Building serverless GraphQL APIs on AWS allows you to run robust backends without managing physical servers, automatically scaling to meet user demand. This text-based course guides you step-by-step through setting up a fully serverless API from scratch, ensuring you grasp both the foundational concepts and practical implementation details. You will transition from understanding basic cloud API architecture to confidently designing, deploying, and mapping GraphQL operations to serverless functions. What you'll learn: - Understand the core principles of serverless architecture, GraphQL schemas, and AWS AppSync integration. - Configure AWS Lambda functions to handle targeted query and mutation operations. - Map GraphQL resolvers to serverless backends using modern infrastructure-as-code principles. - Implement secure authentication and authorization flows for cloud-based APIs. - Monitor and troubleshoot serverless GraphQL operations using cloud observability tools. This course begins with a clear introduction to serverless concepts, schema design, and cloud security basics. You will then progress through structured, text-based modules that walk you through writing resolver logic, configuring AWS integrations, and testing your API endpoints. This course is designed for beginner backend developers, frontend engineers looking to expand into cloud architecture, and web developers new to serverless systems. No prior AWS or GraphQL experience is required. Start reading today to build scalable, serverless APIs in the cloud.
