The document provides an overview of serverless computing on AWS for .NET developers, detailing its advantages such as reduced operational and development costs, along with limitations like execution duration and cold starts. It lists the languages and platforms supported, including Node.js, Python, and .NET Core, and outlines coding techniques with AWS SDKs and tools. Additionally, it addresses AWS Lambda's integration and execution models, and highlights potential pitfalls in serverless application design.
FaaS on AWS for .NET developers
- 1. FaaS on AWS for .NET developers Taras Romanyk .NET Technical Lead
- 2. What is Serverless? Run code without managing operating system Horizontal scaling Reduce operation cost Reduce development cost Improved Latency and Geolocation No specific framework Limited in execution duration Startup latency and “cold starts” Multitenancy problems
- 3. What isn’t Serverless? PaaS Containers Stored Procedure as a Service
- 4. Platforms Azure Functions Amazon - AWS Lambda Functions Google Cloud Functions IBM Cloud Functions (based on Apache OpenWhisk) Oracle Cloud Fn Alibaba - Function Compute
- 5. How to start AWS Free Tier 12 month free Always free Setup a billing alert
- 6. Supported languages & platforms Node.js (4.3/6.10/8.10) Python (2.7/3.6) Java (8) .NET Core 1.0/.NET Core 2.0 Go (1.x)
- 7. We are using... Node.js (4.3/6.10/8.10) Python (2.7/3.6) Java (8) .NET Core 1.0/.NET Core 2.0 Go (1.x)
- 8. Lambda execution model Synchronous (push) Asynchronous (event) Stream-based
- 9. Use cases
- 10. AWS integrations 18 geographic Regions + 4 in progress 98 services
- 11. AWS Lambda Limitation 3008 MB allocated CPU 5 min execution
- 12. Step functions Orchestrate AWS Lambda functions
- 13. Pitfalls: cold start Warm in background Warm with CloudWatch JavaScript, Python Remove access to VPC
- 14. Pitfalls: price for API Gateway
- 15. How to code on Python Boto 3 Moto: Mock AWS Services LocalStack Placebo Cloud9
- 16. AWS SDK for .NET AWS SDK for .NET AWS SDK for Unity AWS SDK for Xamarin
- 17. AWS Toolkit for Visual Studio AWS Lambda Project (.NET Core) AWS Serverless Application (.NET Core) NodeJS
- 19. AWS Serverless Application (.NET Core) CloudFormation SAM (Serverless Application Model) Xunit YAML/JSON
- 20. Deployment All at once Blue/Green Canaries/Linear

- #3: https://martinfowler.com/articles/serverless.html
- #4: If your PaaS can efficiently start instances in 20ms that run for half a second, then call it serverless. PaaS – scaling per request Container – container shape and size management, AWS Fargate SP – hard to test, specific language, deployment
- #5: DEMO!!!!!!!
- #6: Enable price notification https://aws.amazon.com/free/
- #10: API gateway + lambda + DynamoDB Event on media file load Event on image processing Analytics?
- #13: It is like Azure durable function AWS Step Functions is part of the AWS Serverless Platform, and makes it simple to orchestrate AWS Lambda functions for serverless applications.
- #14: Warm with CloudWatch smart warm, background warm, JS, Python
