Recently, we got an inquiry from a banking client to implement SharePoint for their internal team, mainly for document management and approval workflows.
The first question they asked was about the difference between SharePoint Online vs. SharePoint on-premises. Should they go for SharePoint Online, which is a part of Microsoft 365, or should they go with SharePoint on-premises, which will be hosted in their own data center?
So, I thought to write a complete tutorial on everything about SharePoint Online vs. SharePoint On-premises, including architecture, cost, customization, security, user experience, and more—to help you identify which fits your organizational goals.
SharePoint Online and On-Premises Deployment Models
What is SharePoint Online?
SharePoint Online is Microsoft’s cloud-based offering within the Microsoft 365 suite. It eliminates the need for servers, patches, or manual updates by offloading infrastructure management to Microsoft.
Organizations subscribe on a per-user basis and gain access to features like integrated Teams collaboration, OneDrive synchronization, Power Platform support, and continuous updates.
The cloud model ensures that businesses stay on the latest version with minimal effort, and employees can access sites, documents, and workflows from anywhere through secure web access.
What is SharePoint On-Premise?
SharePoint On-Premise represents a traditional self-managed deployment where the platform is hosted within an organization’s data center or private cloud. IT teams configure servers, databases, backup solutions, and patching schedules while maintaining full control over the environment.
Versions like SharePoint Server 2016, 2019, and the more flexible Subscription Edition continue to serve companies that require strict data residency, compliance, or custom solutions unique to their workflows.
Architecture and Infrastructure
Server and Hardware Management
The most obvious difference lies in infrastructure requirements. On-Premise deployments depend on physical or virtual servers, SQL databases, and network configuration. IT teams
