In simple terms:

• SharePoint Server is like having your own in-house file server and collaboration platform. You have complete control but also the responsibility for everything.

• SharePoint Online is like renting space in a large, managed office building. Microsoft takes care of the building's upkeep, and you can focus on using the space.

The best choice for your organization depends on your specific needs, resources, and IT strategy.
