SharePoint Server vs. SharePoint Online Decision Considerations

The business objective should take center stage when deciding between server and hosted SharePoint deployment options, according to a Gartner Catalyst presentation this week.

That main point was highlighted by Kyle Davis, a research director for technical professionals at Gartner Inc. He spoke at the San Diego event on Wednesday in a session titled, “How to Choose Between SharePoint Server, SharePoint Online and SharePoint on IaaS.”

Which SharePoint deployment model to use is a complex question for organizations. Gartner publishes decision frameworks, decision factors, and lists of strengths and weaknesses to help.

Davis recommended keeping a focus on the business objective with SharePoint. What that means is that an organization typically wants to have an intranet or an extranet that will get used by business users and that has some business content when deploying SharePoint, he explained.

Decision Frameworks
Gartner includes SharePoint Server in its decision frameworks as an assumption. About 70 percent of Gartner clients have SharePoint Server on premises today. Many organizations are heavily invested in SharePoint Server, Davis explained. Meanwhile, Microsoft has been putting its innovations in SharePoint Online, so that’s a consideration, too.

Previously, organizations were just faced with a SharePoint Server upgrade questions. Today it’s a more complex situation. Organizations face deployment questions such as “if, when and where,” Davis said.

In following Gartner’s decision frameworks, organizations likely won’t end up with a single decision list. The frameworks typically result in the production of two to three lists, Davis said.

Decision Factors
Gartner has 29 deciding factors to consider in making a SharePoint deployment decision. Davis presented just a few of them.

Compliance and privacy. This decision factor is the No. 1 show stopper when moving SharePoint Server to the cloud, Davis said. If you can get these factors met, then there’s still a question about trusting Microsoft as a vendor. Things such as National Security Agency spying and leaked metadata have put fear into organizations, he added. About 25 percent of respondents in a Gartner survey indicated that they weren’t planning to move to the cloud, and a third of those respondents said it was because of legal constraints.

Data sovereignty. Data sovereignty is a common concern in moving to the cloud, especially for companies in regions outside the United States, Davis said. There’s less control over this factor with SharePoint Online and SharePoint IaaS.

Sites with poor wide area network (WAN) connections. Remote sites sometimes have poor uplinks. In such cases, they usually get their own local SharePoint deployments. Moving these sites to SharePoint Online can be a problem because you have to be online to use the service. Organizations can face getting more trouble tickets if there’s a poor user experience accessing SharePoint Online. In contrast to SharePoint Online, organizations get a bit more control with infrastructure-as-a-service (IaaS) SharePoint deployments, such as using Amazon Web Services infrastructure to host SharePoint, Davis said. He noted that Riverbed has WAN optimizers to compress the content going over the wire that could help.

Scalability and capacity management. Davis highlighted the SharePoint search role as a potential scalability concern. He said that SharePoint Online is part of a multitenant environment and that fact could affect search performance. He recommended avoiding SharePoint Online if an organization is experiencing scalability and capacity management issues. This factor isn’t a problem so much with premises-based and IaaS-based SharePoint deployments.
