S3 Integration with AWS Lambda in C# and .NET

In modern cloud architecture, responding instantly to data changes is essential for building scalable applications. This written course guides you through the process of integrating AWS Lambda with S3 storage using C# and .NET, teaching you how to automate file processing, handle uploads, and manage storage events seamlessly. You will transition from understanding serverless fundamentals to writing clean, production-ready handler code that responds to storage triggers. What you will learn: Understand the core concepts of serverless architecture and S3 event-driven triggers; Configure S3 buckets to invoke AWS Lambda functions automatically; Write C# Lambda handlers using modern .NET dependency injection and configuration patterns; Parse and process S3 event payloads to extract metadata and object details; Implement robust error handling, logging, and retry policies for resilient processing; Apply security best practices using IAM roles and the principle of least privilege. The course begins with foundational concepts, establishing a clear understanding of cloud storage and serverless execution models, before moving into step-by-step implementation patterns and code walkthroughs. This course is designed for beginner to intermediate .NET developers and cloud enthusiasts who want to learn serverless integration without needing prior AWS experience.
