Introduction

Provider-hosted apps for SharePoint include components that are deployed and hosted outside the SharePoint Farm. They are installed to the host web, but their remote components are hosted on another server. In this article the website is hosted in the Microsoft Windows Azure and the app is installed in Office 365.

In this article you will perform the following procedure.
  1. Sign up for an Office 365 Developer Site
  2. Sign up for an Azure trial subscription
  3. Set up an App Catalog in Office 365
  4. Create a Provider-Hosted App using Visual Studio 2013

Set up an App Catalog in Office 365

In SharePoint 2013 there is a special site collection that holds the apps called the App Catalog. There cannot be more than one App Catalog site collection in a web application or each web application can have only one App Catalog site collection. An app catalog is a dedicated site collection in a SharePoint 2013 web application (or a SharePoint Online tenancy) that hosts document libraries for apps for SharePoint and apps for Office. Administrators can upload apps for Office manifest files to the app catalog for use within their organization.

Please refer to How to set up an App Catalog on SharePoint 2013 Online for more details.
