  • 1. SharePoint Apps model overview new challenges, new architecture 23/04/2014 – V1.0
  • 2. Competitive forces • We want to pay only for what we need! • We want you to be quicker than wind! • We want the better quality for us! • We want it cheap! • We want to control what we are doing with our environments • We want to develop the easiest way 2
  • 3. Competitive forces QUICK ACCESS to SPECIFIC NEED SCALABILITY and STABILITY 3
  • 4. The answer? • Cloud model with multi-tenants • Control what is running on each environment • Microsoft cloud platform – Major platforms in the Microsoft ecosystem available online – Owned and operated by Microsoft – Microsoft is a major competitor and goes quickly 4
  • 5. The answer? • Easier upgrade • Multi-hosts capability • Better integration • Multi-devices • SharePoint not required locally for dev purposes 5
  • 6. App for SharePoint Defined • "There's an App for that" – Popular catch phrase that demonstrates the popularity of App Stores • Like an App on a phone, Apps for SharePoint provide functionality that extends SharePoint • Installed on a specific SharePoint Web but always runs somewhere other than SharePoint • Rectangle thru which users interact with functionality 6
  • 7. Technologies used for the apps • HTML (5) • CSS • JavaScript • No SharePoint server-side code! • Need some server-code? It must be hosted outside 7
  • 8. App Shapes for SharePoint 8
  • 9. Chrome Control • Present the navigation header of the Host Web in a block element on the App page • Register the SharePoint ChromeControl JavaScript using a <script> tag • Provide an HTML block element to put the header into • The control inherits its appearance from the Host Web • Customize the control using the available options 9
  • 10. App Licensing • 1 License for each App on each Host Web • Perpetual or Trial • All user or multiuser • Free, Trial, Paid, or Site • With or without an expiration date • 15, 30, 60 days, unlimited, OR Perpetual • Per user or Unlimited • Free or Paid • Only applies to Apps in the SharePoint Store • Microsoft currently receives a 20% fee for paid Apps in the SharePoint Store 10
  • 11. Authentification & authorization • Specific set of permissions • If user has the ability to grand permissions, app can be installed • SharePoint-Hosted apps have the benefit of using built-in security • Oauth is required for Self-hosted and Azure- Provisioned apps 11
  • 12. App rights • Default rights : Read, Write, Manage and Full Control • Not possible to customize • Apps are granted permissions to a scope and all children of the scope • Defined in declarative XML 12
  • 13. Impacts • New model based on well-known architectures • New way for doing business – Sell to the mass – Expose online apps in SharePoint • New way of thinking about IT and services 13
  • 14. Tools • Office Developer Tools in Visual Studio 2012+ • Napa for SharePoint/Office 14
  • 15. Napa for SharePoint • Develop on the cloud from any device • HTML/CSS/Javascript • Available for free • Can be opened in Visual-Studio 2012+ • Many great dev features 15
  • 16. Hosting models • SharePoint-hosted • Cloud-hosted (AKA self-hosted) – Provider-hosted (On-premise, ISP, etc.) – Azure-Autohosted (Office 365) • Hybrid – SharePoint-hosted but depend on Cloud resources – Cloud-hosted but depend on SharePoint resources 16
  • 17. SharePoint-hosted Apps • App resources are hosted in SharePoint but code only runs in the client browser • Code is HTML and JavaScript, no server-side code can run at all • Unless deployed using JSOM, no JavaScript on the Host Web • App resources are stored in an App Web • Deployed entirely to SharePoint 17
  • 18. Provider-hosted • All files are located on an external server • Pre-deployed Web/Database: – On-premise – Third-party (ISP) hosting service • Web content NOT hosted on SharePoint's Azure • Content can use any Web technology • Content can be common for all tenants • If a WSP is included, an App Web is generated 18
  • 19. Azure-Autohosted • Auto-deployed Azure Web/Database • Azure Web Site – Limit 1 – ASP.NET (including MVC) • Azure DB – Limit 1 – Limits during preview • 1 GB in size • Not in SharePoint Store • Workflow – No Limit – 2013 Workflow Manager 19
  • 20. Auto-hosted options • Provider-hosted: Lots of Users, Few Apps • Azure Autohosted: Lots of Apps, Few Users 20
  • 21. Hosting options summarized 21
  • 22. Hosting options summarized 22
  • 23. Characteristics Of An App for SharePoint • Always Web-scoped • Always installed the Host Web • Always contain an AppManifest.xml file that defines characteristics about the App • Never run server-side code on SharePoint server • Optionally, house App resources on an auto- created subweb called the App Web 23
  • 24. Structure of an App 24
  • 25. Host Web • Web where the business user installs the App • The user interacts with the App on the Host Web • Only limited SharePoint resources allowed: – App Parts – Custom Actions • App resources can be housed in an App Web or elsewhere on the Web 25
  • 26. App Web • Dynamically created subweb, created when the App Package includes a WSP • Used to store Web resources: – Pages, CSS, Images, JavaScript, etc. • The App Web is used to store SharePoint resources: – Master Pages, Lists/Libraries, SharePoint Lists, Site Columns and Content Types, Web Parts, etc. • Isolated endpoint the App can securely call using client side code (CSOM, JSOM, REST) • The App always has Full Control of its App Web 26
  • 27. App configuration for on-premises farm • Ensure that App service application and subscription service are created and running in farm • Subscription service is used to provide unique Site Collection ID for App Urls • Apps will be hosted on own domain, within their own frame – Leverages web browser same-origin policy for script isolation • URL naming – each app has unique URL – one app = one URL – http://default-appUID.apps.contoso.com – appUID – combination of site collection ID and particular SPWeb where app is installed http://sp/sites/web http:// /sites/web/appguidtenant-apphash1.contosoapps.com main SharePoint site app1 SharePoint site http://apps-87e90ada14c175.contosoapps.com/sites/web/014c9c59-5d9c-4a59-a5ce-2116a4c90296

  • 31. How to choose the API 31
  • 32. Sandboxed Solutions • Sandboxed solutions are deprecated • Really? • Sandboxed code is deprecated and should not be used anymore • Sandboxed solution without code are used for App Web with CAML declarative XML 32
  • 33. App Stores • SharePoint Store – Managed by Microsoft – Must be a Microsoft Seller to upload an App – Handles discovery to purchase to updates • Web Application App Catalog – Managed in SharePoint Central Administration – Company-developed or purchased Apps • Apps in Testing – Managed in a Developer Site – Sideloaded by Napa/Visual Studio – Intended for testing Apps only 33
  • 34. App Catalogs 34
  • 35. SharePoint 2010 applications • Full-trust farm solutions and sandboxed solutions are still available • SharePoint 2010 developments still work in SharePoint 2013 • Small changes can be required 35
  • 36. Next steps? • Speak about cloud-model around you! • Office 365 trial subscriptions • 5-days Training session @ Boost-IT in the next few months 36
