🆚 SharePoint Online vs SharePoint On-Premises

When choosing a collaboration and document management platform, many organizations face the same question:
Should we use SharePoint Online or SharePoint On-Premises?

Both options are built on Microsoft SharePoint, but they differ significantly in cost, control, maintenance, scalability, and future readiness. This guide breaks it down in simple terms so you can decide which model fits your organization best.

🧭 SharePoint: Cloud or Server? Choosing the Right Path

Microsoft SharePoint is a powerful platform for managing documents, collaborating with teams, and building internal portals. However, SharePoint comes in two deployment models:

SharePoint Online – cloud-based
SharePoint Server – hosted on your own servers

The right choice depends on your business goals, IT maturity, and compliance requirements.

📌 What Exactly Is SharePoint?

At its core, SharePoint is a web-based platform that allows teams to:

Store and organize documents
Collaborate on files in real time
Share news and updates
Automate business processes

Think of it as a central hub for your organization’s content, communication, and workflows.

🔍 Key Differences Between SharePoint Online and On-Premises

While both versions share core functionality, the way they are deployed and managed is very different.

SharePoint On-Premises
Installed on your own infrastructure. Your IT team manages servers, patches, and upgrades.

💰 Cost

SharePoint Online
Subscription-based pricing with predictable monthly or annual costs and low upfront investment.
SharePoint On-Premises
High initial costs for hardware, licenses, and setup, plus ongoing maintenance expenses.

🎨 Customization

Customization through Power Platform, SPFx, and supported APIs—powerful but within Microsoft’s cloud boundaries.
SharePoint On-Premises
Full control over the environment, allowing deep and unrestricted customizations.

🔐 Security

SharePoint Online
Enterprise-grade security managed by Microsoft, including compliance certifications and built-in protection.
SharePoint On-Premises
Full responsibility lies with your organization to secure data, servers, and access.
