SharePoint On – Premises VS. SharePoint Online (2013)

If you’re having a hard time selecting between Sharepoint On – Premises, and SharePoint online of Office 365, this next article is for you.
This article provides a basic overview of the primary differences between SharePoint Online and SharePoint On Premises. So let’s begin by taking a look at the different environments needed to run Online vs On Premises:

SharePoint Environments

As with any on-premise vs cloud based discussion, one of the most significant differences is the impact on internal resources. On-premise solutions require an internal IT support structure including people, hardware and software, or the use of a Managed Service Provider (MSP). Cloud based solutions reduce the dependency on internal resources and typically provide better globally deployed failover and redundancy features.

On Premises	Online
The SharePoint server farm is within the corporate network. The IT Support team maintains the SharePoint farm and regularly applies Microsoft patches and updates. On premise Active directory is used for authentication. Full access to use and customize any SharePoint feature as needed. Availability of Enterprise level services such as BCS, Performance Point, etc.	The SharePoint sites reside in the Microsoft Data Centre (MDC). Microsoft applies the patch regularly. Microsoft’s SLA ensures 99.9% availability. Microsoft’s global network of data centers provides reduced latency and high network bandwidth. Support for Client Side Object & App model.
