What I found surprised and impressed me.
The Office 365 Development Platform
We’ve gotten really good at spinning up web applications that help users solve problems and increase productivity. That’s great, but it can also leave users with all sorts of disparate applications and stand-alone tools to interact with throughout the day. This contributes to a common productivity disrupter: context switching – that is, the need to frequently switch between different applications and user experiences.
Office 365 offers new compelling ways to integrate external services and custom functionality directly into the Office applications people already use.
Users can do more without having to alt-tab their way through the day, and developers can leverage a rich set of features and functionality without re-inventing the wheel.
What’s more, the functionality you add is available from anywhere, on any device. Office 365 provides rich browser-based web apps as well as native apps for Windows, iOS, and Android.
Office 365 Add-ins
The beauty of this architecture is that you can build Office 365 Add-ins using your favorite web technology stack.
An add-in is hosted outside of the Office 365 environment as an independent web application. The beauty of this architecture is that you can build Office 365 Add-ins using your favorite web technology stack. Want to write an ASP.NET app hosted in the Microsoft Azure cloud? Great. Want to use Node.js hosted in Linux? No problem. A Single Page Application using AngularJS? Sure!
With Office Add-ins you can do things like:
- Interact with Outlook items, such as email messages and calendar items.
- Integrate content from external services into Excel and PowerPoint documents.
- Add functionality via a Task Pane to Word.
SharePoint Add-ins allow developers to extend and interact with the rich feature set provided by the SharePoint platform, including SharePoint Online integrated with Office 365.
Since code for SharePoint Add-Ins runs on servers separate from SharePoint, administrators have peace of mind that an Add-in cannot cause any harm to SharePoint servers or degrade their performance. And with provider-hosted Add-ins, you can integrate all the functionality of a full-scale web application with SharePoint content.
Unlock Your Business Data
Sure, Office 365 Add-ins allow you to pull content and applications directly into Office applications, but what about the other way around?
Here Office 365 also delivers. The new Graph API provides unified access to Office 365 assets. For SharePoint-specific assets like lists, SharePoint APIs come in several flavors including the SharePoint REST API and Client Side Object Model (CSOM), and are available for both SharePoint Online and SharePoint Server 2013.
These APIs provide tremendous access to the wealth of business data and assets inside Office 365, including people, calendars, emails, documents, tasks, notes and other files.
All access to these resources is secured with the credentials of the Office 365 user via Azure Active Directory (AAD) authentication and authorization. With AAD you can also configure an application to be authenticated and authorized so that programs like background services and web jobs can access Office 365 assets.
