Introduction to Serverless with AWS Lambda in C#
summary
Defines serverless as “less server” and demonstrates a working pipeline: a .NET MAUI mobile app posts images to an API Gateway HTTP Lambda, Lambda stores originals in S3, an S3-triggered Lambda generates 200×200 thumbnails and reuploads them. Uses AWS Toolkit for Visual Studio, AWS SDK (Amazon.S3), Lambda Annotations and AWS Lambda hosting for ASP.NET Core. Reports 300–400 ms cold starts with Native AOT and concrete billing examples like $0.14/month for 79 MAU and a thumbnail pipeline that successfully runs live.
