7. Serverless is to servers as wireless is to wired.
Wireless internet required wires, yes, but
customers don't need to interact with them.

16. Distributed Architecture
• Design stateless and ASync solutions to enable scaling.
• Connect with other Azure Services via triggers and bindings.
• Leverage proxies for API abstraction and composition.
• Use Logic Apps to orchestrate workflows
• Use managed connectors to abstract calls to cloud and on-premises services.
Cloud DevOps
• Design for automation. Use ARM templates.
• Design DevOps for the cloud: safe deployment with test/development and
production environment separation and test on the target platform.
• Monitor the running apps with App Insights and tune for best experience.

21. Cloud APIs and
platform functionality
API connections

22. Protocols/Native
XML & EDI
Hybrid
Cloud APIs and platform
• Supports over 125 built-in connectors
• Scales to meet your needs
• Enables rapid development
• Extends with custom APIs and
Functions
API connections
• Authenticate once and reuse
SaaS

23.  Workflow in the cloud
 Powerful control flow
 Connect functions and APIs
 Declarative definition to
persist in source control and
drive deployments

24. Templates

27. Creates new instances
of Logic Apps
• Runs based on a defined schedule.Recurrence
• Serves as an endpoint that you call via an HTTP
Request.Request
• Poll a specified endpoint and check the response in
order.HTTP
• APIConnection is a polling trigger that calls Managed
connectors.APIConnection
• Calls out to a specified URL to register and unregister.HTTPWebhook
• Is a webhook trigger that subscribes to a webhook
from a managed connector.
ApiConnection
Webhook
• Debatch an array into separate instances.Split
• Allow only one instance of a Logic App to run at a
timeSingleton

31. Collections
• Encapsulates a set of actions.
• Can be used for error handling and
compensation.
Scope
• If…Else conditions
• Can be nested
Condition
• Determines which path to take based on
values in case statementsSwitch Case
• Iterate over a list of items.ForEach
• Loop until a condition is met.
• Exit criteria can be time or condition.
Until

32. Built-in functions

63. Developer experience
 Same consistent Programming Model
 Same Azure Functions portal
 Publish directly from Visual Studio tooling
 Leverage triggers: timer trigger and new SQL Service Broker trigger
Administrator features
 Take advantage of Azure Functions on premises
 Workers can run in spare compute – i.e. desktops left on overnight within orgs
 Only provision two types of roles
 Management Role – Hosts Portal, Publishing Endpoint and
 Worker Role – Runs Function in Windows Server Containers

66. Azure Functions Core Tools
 Provides the entire Functions runtime
 Trigger off of Azure events and debug locally
JavaScript
 Use Visual Studio Code or any Node debugger
C#
 Use Visual Studio 2015 or 2017
 Use class libraries with attributes in Visual Studio 2017

67.  Based on class libraries
 Get the full power of
IntelliSense, unit testing, and
local debugging
 Use WebJobs attributes to
define triggers and bindings

69.  Supports Node.js v6.5.0
 Supports JS and TypeScript
 You can use the callback or
return a Promise
 VS Code support for local
debugging via CLI
 VS Code supports rich
Node.js debugging

70. Deploy

71. Resource deployment
• Azure Resource Manager (i.e. ARM)
Content deployment
• Visual Studio
• Azure CLI (Logic App)
• Azure Functions Core Tools (Function App)
• CI/CD
Safe deployment practices
• Use Azure Functions deployment slots for environment separation and swap
deployments
