Getting Started: Building .NET Applications on AWS

Learn how to build modern .NET Applications using Amazon Web Services features and services for production.

About This Course

Want to run your .NET apps on AWS but not sure where to start? This course has you covered. James Eastham walks you through building real .NET applications on Amazon Web Services, from setting up your infrastructure with AWS CDK to deploying containers, serverless functions, and everything in between. You'll work with the services that matter most: DynamoDB, S3, SQS, SNS, EventBridge, Lambda, and even Amazon Bedrock for AI. James shows you how to wire them up in your C# code and define your infrastructure as code using the CDK. The Lambda section alone is worth it, covering the Annotations Framework, running ASP.NET Core serverless, SnapStart for faster cold starts, and Native AOT for peak performance. Whether you're moving existing .NET apps to AWS or building cloud-native from scratch, this course gives you the practical skills to ship with confidence.
