- 4. Azure Functions Create a “serverless” event-driven experience that extends the existing Azure App Service platform by building “nanoservices” that can scale based on demand
- 5. Supported Languages and Tools Create functions in JavaScript, C#, Python, and PHP, as well as scripting options such as Bash, Batch, and PowerShell, that can be triggered by virtually any event in Azure, 3rd party services, or on premise systems
- 6. Common Scenarios Your App or Service Office 365 Office Graph Azure Storage Other Functions Legacy Systems Web Services • Timer-based processing • Azure service event processing • SaaS event processing • Serverless web application architectures • Serverless mobile backends • Real-time stream processing • Real-time bot messaging
- 7. Function App Templates Function App templates are categorized into general areas of Timer, Data Processing, and Webhook & API • BlobTrigger • EventHubTrigger • Generic webhook • GitHub webhook • HTTPTrigger • QueueTrigger • ServiceBusQueueTrigger • ServiceBusTopicTrigger • TimerTrigger • Blank & Experimental
- 8. Timer Function Apps • Run at explicitly specified intervals, like every day at 2:00 am using CRON expressions, like “0 */5 * * * *“ (every 5 minutes) • Can send information to other systems, but typically don’t “return” information, only write to logs • Great for redundant cleanup and data management • Great for checking state of services • Can be combined with other functions
- 9. Data Processing Function Apps • Run when triggered by a data event, such as an item being added to a queue or container • Typically have in and out parameters • Great for responding to CRUD events • Great for performing CRUD events • Great for moving content • Access data across services
- 10. Webhook & API Function Apps • Triggered by events in other services, like GitHub, Team Foundation Services, Office 365, OneDrive, Microsoft PowerApps • Takes in a request and sends back a response • Often mimic Web API and legacy web services flows • Typically need CORS settings managed • Best for exposing functionality to other apps and services • Great for building Logic Apps
- 11. code Anatomy of a Function • A “Run” file that containing the function code • A “Function” file containing all service and trigger bindings and parameters • A “Project” file containing project assembly and NuGet package references • App Service settings, such as connection strings and API keys .NET Core and Project references Function configuration Executable code
- 12. Function Bindings Type Service Trigger Input Output Schedule Azure Functions ✔ HTTP (REST or webhook) Azure Functions ✔ ✔* Blob Storage Azure Storage ✔ ✔ ✔ Events Azure Event Hubs ✔ ✔ Queues Azure Storage ✔ ✔ Tables Azure Storage ✔ ✔ Tables Azure Mobile Apps ✔ ✔ No-SQL DB Azure DocumentDB ✔ ✔ Push Notifications Azure Notification Hubs ✔ Bindings serve as the basis for all connections to and from a function. Many bindings can be “bi-directional” as well.
- 13. Testing Functions • Command-line tools • 3rd party products such as Postman and Swagger • Direct web calls via cURL • Nested functions • Microsoft Azure Storage Explorer • Visual Studio Cloud Explorer
