AWS API Gateway: Direct Integrations for Serverless Architecture

Building serverless applications often relies too heavily on Lambda functions, leading to unnecessary cold starts, increased latency, and higher cloud bills. You can bypass Lambda entirely by connecting your API Gateway directly to downstream cloud services. This text-based course guides you through designing and implementing direct integrations, helping you build highly performant, low-latency, and cost-effective serverless backends. What you'll learn: - Understand the core concepts of API Gateway integration types, execution roles, and VTL (Velocity Template Language). - Configure direct integrations with DynamoDB for database operations and SQS for message queuing. - Apply robust security patterns using IAM policies, API keys, and Cognito authorizers. - Implement request validation and data transformation using JSON Schema and mapping templates. - Monitor and debug integration pipelines using CloudWatch logs and structured logging. You will start with foundational API gateway concepts and mapping basics, then progress through step-by-step written explanations for building real-world integrations without writing a single line of Lambda code. This course is designed for cloud developers, architects, and serverless beginners who want to optimize their cloud infrastructure. No advanced programming experience is required. Start reading today to unlock the full potential of high-performance serverless design.
