This document provides an overview of Azure Functions and serverless computing. It begins with welcoming attendees and thanking sponsors. It then introduces the presenter and their background. The document defines Azure Functions and serverless computing, outlines their benefits, and describes key concepts like triggers, bindings, and application components. It compares Azure Functions v1 and v2 and provides a demo. It also discusses where Functions fit and lists some open source Microsoft products.
Unleash the power of Serverless Computing
- 2. A BIG thank you to the 2019 Global Sponsors! @codestellar
- 3. Another BIG thank you to local sponsors! @codestellar

- 7. What are Azure Functions? Execute your code in response to any event @codestellar
- 8. Event-driven scale Micro-second billing Abstraction of servers What is Serverless? @codestellar
- 9. Benefits of ‘SERVERLESS’ Manage less Micro-pricing Ease of scale @codestellar
- 10. Key Concepts • Function App: Unit of development, deployment and scaling. Can have many functions. • Triggers: Event Source that invokes the function. One per function. • Bindings: • Input: Data that is pulled in at the start of execution. Can be multiple. • Output: Data that is pushed out after the execution. Can be multiple. https://docs.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings
- 11. Serverless Application Platform Components @codestellar
- 12. Consumption Plan New Premium Plan (Preview) Instance Size Fixed at 1 core and 1.5 GB of memory Configurable up to 4 cores and 14 GB of memory Scaling Event Driven Scaling Event Driven Scaling Scale Controls None Set min and max instances Private Networking None VNET Integration Warmup Time (Cold Start) Your app must be loaded after it is inactive No delay after your app is inactive and scale instantly to pre-warmed instanced Cost Consumption Consumption and at least 1 pre- warmed instance
- 13. Azure Functions v1 vs v2 • Keys for calling function endpoints are stored in blob storage in V2. Earlier it was file storage by default • All functions in a function must have same language (Runtime stack) • You can set maxConcurrentRequests. Default 100 • For better monitoring, APPINSIGHTS_INSTRUMENTATIONKEY is used. • https://docs.microsoft.com/en-us/azure/azure-functions/functions- versions @codestellar
- 14. Who wants a goodie? In how many regions, Azure is generally available? Azure is generally available in 44 regions around the world, with plans announced for 10 additional regions. https://azure.microsoft.com/en-us/global-infrastructure/regions/ @codestellar

- 17. Where Functions Fit? Processing on top of event streams (IoT, Event Hubs) Web API(s) and Mobile Backends Glue between Systems Automating Scripts and Jobs Pub/Sub Patterns
- 22. Who wants a goodie? Name three open source products by Microsoft? VSCode, .Net Framework, Calculator @codestellar
