- BYO – Data centre, or “server room”; HA? IaaS – Rent a server PaaS – Rent a Platform (worry about the app, not the server) “Serverless” – just gimme the app!
- Abstraction of servers Event=driven / instant scaling - Micro-billing
- Focus on the business logic Faster time to market
- Focus on the business logic!
- Lets talk about what really makes up MSFT’s Serverless platform: At the center of the Serverless platform, is our compute offerings: Azure Functions and Azure Logic Apps. Azure Functions is an event based Serverless compute experience that helps you accelerate your development. Logic Apps is a powerful workflow and orchestration tool. It enables building a Serverless app in minutes – by orchestrating multiple functions using a visual workflow tool. Say you have your apps up and running using Serverless. Congratulations! You now need to collect intelligence from different apps across platforms to take actions upon. There are a few essential components which we think are core to building Serverless applications are: Data/ Storage –Functions has triggers and bindings with Azure document DB and Azure Blob storage ** Triggers: Triggers are event responses used to trigger your custom code. They allow you to respond to events across the Azure platform or on premise. ** Bindings: Bindings represent the necessary meta data used to connect your code to the desired trigger or associated input or output data. Messaging such as queues and topics using Azure Service Bus and Azure Event Hubs Integration – that includes core LOB apps and SaaS apps integration via Azure Logic Apps. Intelligence on data and sentiment/ predictive analysis using Cognitive services and Machine learning Conversation as a service – how do we equip developers to build apps that offer an end-to-end experience for their end users – Azure Bot Service offers a Serverless interactive bot experience. More, developers are spending more time writing code that allows them to add huge business impact with Serverless. MSFT offers numerous development tools such as IDE Support for Visual Studio in functions and Logic Apps, enables local development (vs web browser coding environment), visual debugging capability, all with your tools of choice. Lastly, I also want to highlight top scenarios and use cases for Serverless: Real-time Stream analytics: Customers can use Functions to feed real-time streams of data from application tracking into structured data and store it in SQL online. SaaS event processing: Customers can use Functions and Logic Apps to analyze data from an excel file in Onedrive and perform validation, filtration, sorting and convert data into consumable business charts Web app architecture: Used a lot in creating targeted marketing collaterals – when a customer clicks on a webpage, it triggers a webhook, that uses a function to create an ad that matches the customer profile and displays a completed webpage. Real-time bot messaging: When customers send a message to a chatbox, Functions calls Cortana analytics to generate appropriate answers and sends a response back. //from before: Customers have different paths to build a Serverless app – start by building the distributed application components using functions by leveraging the numerous templates and declarative bindings Or Start with the workflow and orchestration of Serverless application using Azure Logic Apps. The visual designer enables developers to quickly and easily author, edit and visualize orchestration of multiple functions and workflow.
- Call out that we now support SQL Triggers
- Any REST API Postman export, swagger/open api definition, A custom Logic Apps Connector allows you to register a custom HTTP endpoint with operations that will be exposed within Azure Logic Apps", "description": "Use the Logic Apps Connector and editor to build and deploy custom APIs to be consumed within Logic Apps. These APIs can be any RESTful endpoint, including Azure Web APIs, API Management APIs, Azure Functions, and more. Once created, you can open the connector editor to describe the endpoint (via OpenAPI definition or a postman collection), configure how it will display within the Logic Apps designer, and publish the changes

- As I mentioned earlier, triggers and bindings are the things that facilitate easy communication with other services. This chart shows us the triggers and bindings currently supported. As we can see, there are a number of Azure services supported here…. for Storage, Database, Messaging, Notifications and so on. In addition to those, Functions also support generic Http triggers, which means you can easily write a piece of code that can be used to respond to REST requests or requests from any service that supports webhooks. This also provides a really fast and easy mechanism for building extensions to SaaS applications. We are fully committed to making this list grow and making more check-marks appear in that table.

- Azure Functions supports an event based on a timer using CRON job syntax. For example, you could execute code that runs every 15 minutes and cleans up a database table based on custom business logic. Azure Functions supports triggering an event based on an activity in an Azure service. For example, you could execute serverless code that reads newly discovered test log files in an Azure Blob Storage container and transforms this into a row in an Azure SQL Database table.
- Azure Functions can power a single page app. The app calls functions using the WebHook URL, saving user data and deciding what data to display. Or, you can do simple customizations, such as changing ad targeting by calling a function and passing it user profile information. Azure Functions supports triggers based on activity in a SaaS service. For example, when a file is saved in OneDrive, this triggers a function that uses the Microsoft Graph API to modify the spreadsheet, creating additional charts and calculated data.
- For example, IoT devices send messages to Azure Stream Analytics, which then calls an Azure Function to transform the message. This function processes the data and creates a new record in an Azure SQL Database. Azure Functions can be used to customize the behavior of a bot using a WebHook. For example, you can create an Azure Function that processes a message using Cortana Analytics and call this function using Bot Framework.
- OOTB Publishers + Custom Capabilities Here are some of the key features of Azure Event Grid: Simplicity - Point and click to aim events from your Azure resource to any event handler or endpoint. Advanced filtering - Filter on event type or event publish path to ensure event handlers only receive relevant events. Fan-out - Subscribe multiple endpoints to the same event to send copies of the event to as many places as needed. Reliability - Utilize 24-hour retry with exponential backoff to ensure events are delivered. Pay-per-event - Pay only for the amount you use Event Grid. High throughput - Build high-volume workloads on Event Grid with support for millions of events per second. Built-in Events - Get up and running quickly with resource-defined built-in events. Custom Events - use Event Grid route, filter, and reliably deliver custom events in your app.
- Tord Glad Nordahl : “With dynamic scale and consistent performance Azure Event grid lets you focus on your app logic rather than the infrastructure around it."
- Based on Service Fabric 99.99% availability https://docs.microsoft.com/en-us/azure/event-grid/delivery-and-retry 10 seconds 30 seconds 1 minute 5 minutes 10 minutes 30 minutes 1 hour Event Grid adds a small randomization to all retry intervals.

- In this fourth lab, we will be receiving the orders from the business customer’s topic in a new Logic App, and check the total amount of the invoice. In case the customer placed a large order (over $50000), we will create a task for one of our sales employees to contact the customer to verify the order. In case the order is correct, the invoice will be emailed to the customer. The Logic App will then call a function, in which we will check a storage table to determine how much discount the customer will be given (based on the total order amount), and finally will place a file on blob storage, which will be used by an employee to refund the customer.
