Title

AWS re:Invent 2023 - Build production-ready serverless .NET apps with AWS Lambda (XNT301)

Summary

The session focused on building serverless applications with .NET on AWS Lambda.
James Easton and Craig Bossie presented the session, covering development, testing, and deployment phases.
They discussed the benefits of serverless architecture, including avoiding infrastructure-related issues and cost efficiency.
The session highlighted the use of AWS Lambda, DynamoDB, API Gateway, and the Lambda Annotations framework.
They addressed cold starts and performance optimization, including the use of Provisioned Concurrency and AWS Lambda Power Tuning.
Native AOT (Ahead-of-Time) compilation was introduced as a method to improve cold start performance in .NET 8.
Observability and instrumentation were covered, emphasizing the importance of tracing, logging, and metrics using AWS X-Ray and Power Tools for AWS Lambda.net.
Infrastructure as Code (IaC) tools like AWS SAM, CDK, and Terraform were discussed for managing and deploying serverless applications.
Domain-Driven Design (DDD) was recommended for structuring serverless applications to keep them maintainable.
The session concluded with a call to action to use the provided tools and practices to build and deploy serverless .NET applications on AWS.

Serverless architecture with AWS Lambda allows developers to focus on code rather than infrastructure management, leading to increased developer productivity and reduced operational costs.
AWS Lambda's performance can be optimized by adjusting memory configurations and using Provisioned Concurrency to handle cold starts.
Native AOT compilation in .NET 8 offers significant improvements in cold start performance, making it a game-changer for serverless .NET applications.
Observability is crucial for serverless applications due to their distributed nature. AWS X-Ray and Power Tools for AWS Lambda.net simplify the process of implementing observability best practices.
Infrastructure as Code (IaC) is essential for managing complex serverless applications. Tools like AWS SAM, CDK, and Terraform provide different approaches to defining and deploying infrastructure.
Domain-Driven Design (DDD) can help manage the complexity of serverless applications by aligning software design with business functions.
Continuous Integration and Continuous Deployment (CI/CD) practices are applicable to serverless applications, allowing for automated and repeatable deployment processes.
The session provided a comprehensive overview of the end-to-end process of building, optimizing, and deploying serverless .NET applications on AWS, demonstrating the maturity of AWS services and tooling for .NET developers.
