Building Serverless Java APIs with AWS Lambda and API Gateway

Transitioning to serverless architecture can feel overwhelming for Java developers accustomed to traditional application servers. This text-based course bridges that gap, showing you how to leverage your existing Java skills to build highly scalable, cost-efficient APIs on AWS. By completing this course, you will master the fundamentals of serverless computing, moving from basic concepts to deploying production-ready APIs. You will understand how to write efficient Lambda functions, configure secure access controls, and integrate with cloud services to handle real-world tasks like dynamic file processing. What you'll learn: - Understand foundational serverless concepts and AWS Lambda architecture. - Build and deploy Java-based Lambda functions using the modern AWS SDK for Java. - Configure API Gateway to expose your Java functions as secure REST endpoints. - Manage access permissions securely using Identity and Access Management (IAM) policies. - Integrate Lambda with S3 storage and CloudWatch for logging and monitoring. - Optimize Java Lambda performance, including modern strategies to mitigate cold start times. The course starts with core serverless definitions and setup, guides you through writing and deploying your first Java function, and culminates in constructing a practical, event-driven media processing API. This course is designed for Java developers new to serverless development on AWS, requiring only basic Java knowledge and no prior cloud experience.
