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.

Logic Apps
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

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

26. #Gapand2017
 Based on class libraries
 Get the full power of
IntelliSense, unit testing, and
local debugging
 Use WebJobs attributes to
define triggers and bindings

Local development and debugging
#Gapand2017

28. #Gapand2017
 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

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

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
