Designing cloud-only enterprise-grade solutions often poses a challenge: ensuring well known best practices, such as encapsulation and isolation, reusability and separation of concerns, but also standardizing infrastructure-layer tasks such as impersonification, logging and error handling across different cloud business blocks and different technologies, is very different from the way this has been done in the past. This session will be a practical walk-through implementing a Domain Driven Design pattern based reference architecture, using different Azure services and Office 365 data in creating a scalable and robust enterprise-grade cloud solution.

7. What is this session about?
• “Modern”
• Applied known, old, “unmodern” architecture patterns in “modern” cloud solutions
• Focus on Office 365 and SharePoint Online

8. Why this session
• skybow Solution Studio Online
• SaaS offering
• 35000 users at the moment
• Challenges:
• Performance
• Scalability
• Robustness
• Identity, Authentication and Authorization
• Maintainability and operations

9.  Performance
 Scalability
 Robustness and scalability
 Auth, Identity
 Maintainability and operations

10. Not a new phenomenon
• Cobol
• …
• Windows Forms => Database
• PHP => MySQL
• “Classic” SharePoint development: Webparts talk to lists
• ...
• Modern web applications
• Model understood as DAL
• View understood as UI
• Controller understood as BL

12. SharePoint Framework

17. DEMO1: A SIMPLE HELLO WORLD WEBPART

18. What did we do
• MVC web part talks directly to datasource
• (SharePoint Online REST API)
• It works!
• No code reusability
• What are our options?
• Move the code for wine adding and calculation out
• Apply architecture

24. Get to know your toolchain
• Azure Active Directory – Authentication
• JavaScript and Node.JS – front end
• Azure Functions – Business Layer
• Azure APP Service – BL, DAL
• Azure Application Insights – logging, monitoring

25. When to use what – AAD
• Authentication
• Authorization
• Application Management
• Application Capabilities
• Delegated (impersonation) vs AppOnly (Daemons)

26. When to use what – JavaScript and Node.JS
• User Interface - RIA
• Modern WebParts (when in SharePoint)
• Azure Functions (Business Logic)
• AAD secured Applications

27. When to use what – C#, .NET
• AAD secured Web Applications
• Azure Functions (Business Logic)
• Azure API Apps (BL, DAL)

28. When to use what – Azure Functions
• Lightweight BL
• wrappers around API Apps
• Fast development, drawbacks in development and ALM Cycle
• Limited debugging and tracing
• Plumbing less mature than in API Apps

29. When to use what – Azure APP
Service
• Business Layer, Data Access Layer
• Heavy-weight, reliable code
• Mature development cycle
• Use C#
• Good debugging and tracing
• Relatively easy plumbing

30. When to use what – Azure Application
Insights
• Logging
• Monitoring
• Analysis
• Easy plumbing

31. Microsoft Cloud Design Patterns
• msdn.microsoft.com/en-us/library/dn568099.aspx
• Availability
• Data Management
• Design and Implementation
• Messaging
• Management and Monitoring
• Performance & Scalability
