The Cloud Connector for Microsoft SharePoint 2010 and Office 365 takes your local line-of-business data to your cloud-based or any other hosted SharePoint - easy to connect, secure, always up-to-date and bi-directional, if required. Content stored in almost any corporate data source, e.g. databases, files, ERP / CRM / ECMS or other legacy platforms and on-premise applications like Dynamics, SharePoint, Active Directory, SAP etc. is replicated to native SharePoint lists into the cloud via secure web services.
All features of native SharePoint lists are completely available for your external data. While the SharePoint Business Data Catalog (BDC), the SharePoint Business Data Connectivity Services (BCS) "External List" or the SQL Server Integration Services (SSIS) out-of-the-box are not made for cloud-based or sandboxed scenarios, the SharePoint Cloud Connector was specially developed to solve the specific challenges of remote hosted disconnected systems in the cloud without any direct access to corporate business data and very restricted feature customization capabilities.
