Building a serverless REST API with AWS Lambda C# and Amazon API Gateway is one of the fastest ways to ship a production-ready backend without managing a single server. You write .NET 8 handler code, API Gateway routes HTTP requests to it, and AWS scales the whole thing from zero to thousands of requests per second automatically — and you pay only for the milliseconds your code actually runs. In this tutorial you'll build a complete serverless REST API in C#: a Products service with GET , POST , and DELETE endpoints. We'll cover both the low-level Lambda proxy integration model (so you understand what's actually happening) and the ASP.NET Core Minimal API hosting model (so you can reuse your existing skills). Along the way you'll learn why serverless behaves the way it does, how to avoid cold-start pain, and the mis...
