SharePoint On – Premises VS. Share Point Online

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:

Environments Comparisons

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

Feature Comparisons

While the basic functionality of SharePoint remains the same, there are a number of significant feature
differences between On Premises and Online:

Category On Premises Online
Cost Involved Purchase/Maintain Hardware, Software licenses etc. Annual subscriptions for Office 365 Plans billed on a per user basis.
Infrastructure deployment & maintenance. IT Support Team to deploy/manage farm, latest updates or patches not always deployed. Microsoft manages the environment and ensures all updates and patches are deployed.
Business Continuity (BC) Dependent on internal capabilities. Microsoft built-in redundancy and failover for data centers, but does not provide end user backups or data recovery.
Product Features Support for enterprise feature, Office web App (OWA) needs to be installed Missing or limited features, pre-configured features
Customization Options Full support for server side code and client side code, App usage from OAC and SAS Full Support- Client Side, Limited Support-Server side, Can use Apps from OAC or SAS
