Going serverless with azure functions

This document discusses serverless computing with Azure Functions. It describes how Functions as a Service (FaaS) is an evolution from Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) models. Azure Functions is a FaaS solution that allows developing functions using various languages and binding them to triggers and outputs. Functions can be developed locally and deployed continuously to Azure through tools, APIs, or IDEs. Serverless applications in Azure combine Functions for compute, Event Grid for events, and Logic Apps for workflows.
Going serverless with azure functions
- 1. Going Serverless with Azure Functions Giulio Santoli, CSA
- 3. it’s just a matter of EVOLUTION
- 4. from IaaS to FaaS (Function as a Service) Docker Swarm Mesos Kubernetes Function App Cloud Foundry
- 5. PaaS vs FaaS with framework (PaaS) without framework (FaaS) PaaS = Platform as a Service FaaS = Functions as a Service
- 6. FaaS ≤ Serverless FaaS = Functions as a Service
- 8. OpenFaaS Kubeless Fn Project OpenWhisk Azure Functions AWS Lambda Functions Google Cloud Functions https://github.com/Azure/Azure-Functions
- 9. The three musketeers of Serverless Event Grid Serverless Events Logic Apps Serverless Workflow Functions Serverless Compute Storage (Queue, Table, Blob)
- 10. Event Grid Backbone of event-driven computing High reliabilityNear real-time Massive scale-out
- 11. Cloud Native Computing Foundation (CNCF) in partnership with Microsoft, Google, IBM, Oracle and others
- 14. Azure Functions ➢ Charge by GBs + Executions ➢ Limited to 5 mins (up to 10 minutes) ➢ Stateless
- 15. Author functions in C#, F#, Node.JS, Java, and more CodeTrigger/Inputs React to timers, HTTP, or events from your favorite Azure services, with more on the way Outputs Send results to an ever-growing collection of services Triggers & Bindings
- 16. Local development and debugging Visual Studio Code Azure Functions Extensions Visual Studio CLI
- 17. Every 15 minutes Clean tableFind and clean invalid data
- 18. Photo taken and Webhook called Stored in Blob Storage Produces scaled images
- 19. File added to Blob Storage CSV Transform CSV to data rows PowerBI Charts
- 20. Excel File saved on OneDrive Microsoft Graph analyzes content PowerBI Charts
- 21. Supported Languages Language Runtime 1.x Runtime 2.x C# GA Preview JavaScript GA Preview F# GA Preview Java N/A Preview Python Experimental N/A PHP Experimental N/A TypeScript Experimental N/A Batch (.cmd, .bat) Experimental N/A Bash Experimental N/A PowerShell Experimental N/A
- 23. Durable Functions ➢ Programmatic Orchestration ➢ Stateful Singleton ➢ Human Interaction ➢ C# (GA) and JavaScript (Preview)
- 25. Deployment
- 26. o Continuous Deployment Bitbucket, Dropbox, Git local/external, GitHub, OneDrive, VSTS o Command Line Tools PowerShell, Azure CLI, Functions CLI o REST APIs PowerShell, Bash, any software o IDE Integrations Visual Studio, Visual Studio Code, IntelliJ
- 27. ✓ Each function has a folder containing function.json ✓ Dependencies are usually local to each function ✓ One global host.json Directory Tree Structure
- 28. Deploying a Zip File with Azure CLI
- 29. Deploying with REST APIs
- 30. beware of cold starts
- 31. https://docs.microsoft.com/en-us/azure/azure-functions/functions-runtime-install Local Azure Fuction Runtime (preview) ✓ Windows Server 2016 or Windows 10 Creators Update ✓ Needs a local SQL Server instance ✓ Two roles: Managent and Worker
- 32. Summary ➢ FaaS is a further abstraction over PaaS ➢ Serverless concerns compute, events and workflow (and storage) ➢ Serverless adopts a pay-per-use model ➢ Azure Functions is a FaaS solution, supporting a powerful on-prem development experience
