What is SharePoint Online?

SharePoint Online is a cloud-based modern Software-as-a-Service (SaaS) collaboration platform designed to help you to create, store, organize, visualize, and share data, content, and applications. Not only is SharePoint Online a content management platform, but it is also an application development platform. One of SharePoint Online's strengths is the ability to search for data across an enterprise content set, including connected resources such as on-premises SharePoint Server environments or on-premises file servers (with the configuration of SharePoint Hybrid).

In addition to content management capabilities for your online data, SharePoint Online can also connect to on-premises database services. The value proposition of SharePoint Online is to enable users and administrators to focus on providing value to their organizations instead of managing infrastructure:

With SharePoint Online (as well as other services in the Microsoft 365 suite), organizations don't need to purchase and deploy infrastructure of their own. Instead, they can quickly adopt a pre-configured platform as a subscription service and begin using it almost immediately.

For content creators, SharePoint Online features both easy-to-use what you see is what you get drag and drop design, publishing, and categorization tools for content authors, as well as interfaces for coding more complex sites and queries. As a manager of a SharePoint site, you can publish news, upload documents, add links to resources, and visualize data from other parts of the Office 365 ecosystem. Microsoft enables content consumers to access resources via browsers on desktop, tablet, and mobile devices, as well as native mobile applications for Android and iOS platforms:

SharePoint Online, like other services in the Microsoft 365 platform, is licensed on a per-user basis. The following table shows general features and limits of the SharePoint Online service:


Office 365 Business Essentials or Business Premium

Office 365 Enterprise E1, E3, or E5, or SharePoint Online Plan 1 or 2

Office 365 Enterprise F1

You can purchase an unlimited amount of additional storage for your SharePoint Online environment.


Overview of SharePoint Online architecture

The SharePoint Online platform is generally comprised of site collections, sites, web parts, and pages. A site is a website that contains various SharePoint objects such as pages, document libraries, or calendars. A site collection is a group of sites, normally organized by department, project, cross-functional group, or other business units. A page is an HTML web page. Pages can be basic with just displayed text or built from templates (such as Wiki or Publishing Portal) that may have different web parts preloaded.

Web parts are codeless widgets or apps that can be used to display or interact with information on a page:

In the preceding diagram, the Managers (Site) contains three web parts: a calendar, a task list, and a document library. The Document Library web part looks like a filesystem interface to SharePoint and can be used to upload and download files as well as perform other file operation tasks.


Introduction to Office 365 Groups

SharePoint Online is one of the foundational components of the Microsoft 365 collaboration platform. SharePoint Online provides the backend storage and service architecture that many of the Microsoft 365 services utilize for content management, storage, and automation.

In older versions of SharePoint Online and SharePoint Server, document and application content were arranged in sites, which were arranged in site collections. These storage mechanisms and methods were different and disconnected from other applications and services in the Microsoft ecosystem. One of the core differentiating features between legacy on-premises deployments of Windows Server applications (such as SharePoint Server and Exchange Server) and their modern cloud-based counterparts is the availability of a new construct: the Office 365 Group.

Office 365 Groups (also periodically referred to as Modern Groups) are a special type of group object that is built from numerous components. There is an Exchange Online Group Mailbox component for message storage and a SharePoint Online team site used for file and metadata storage. Office 365 Groups can function like traditional distribution lists in that users can be added to or removed from a list and members, but that's where the similarities end.

Whereas a traditional distribution group is transactional (it distributes a message to members but has no history of messages that have been relayed through it), an Office 365 Group has the concept of persistent storage—a feature provided by an underlying Exchange Group Mailbox. Once a message has been sent to an Office 365 Group, it is stored in the group's mailbox and is visible to anyone who joins the group at a later time.

A member of an Office 365 Group can choose to Follow or Stop Following the conversations in their own inboxes. When a user chooses to follow a group in their inbox, they will receive a copy of the message sent to the group (making it function like a classic distribution group for them). An Office 365 Group also has a calendaring component (stored in the Exchange mailbox), a OneNote notebook, a SharePoint Team site, and a default Planner plan available. Office 365 Groups can be joined from Outlook or Outlook Web App. If a user chooses to stop following a group, they will no longer receive a copy of messages sent to the group in their inbox, but they will continue to be able to access the group through the Outlook and Outlook Web App clients.

This Office 365 Group framework is used extensively in SharePoint Online. Office 365 Groups are connected to most Office 365 services, including Planner, Stream, Teams, Yammer, PowerBI, SharePoint, and StaffHub. By default, Office 365 Groups can be created by administrators as well as end users through Outlook or Outlook Web App or by using the various services (Planner, Stream, Teams, and so on) that rely on Office 365 Groups.

Some organizations may wish to limit who can create Office 365 Groups or enforce a naming policy to provide some context for the group. With an Azure Active Directory Premium P1 or higher license, you can manage many features of Office 365 Groups, including who can create them, naming policies (including prefixes, suffixes, and prohibited words), and expiration policies:

Policies you set here will apply organization-wide to all Office 365 Group creation and management activities going forward. The policies that you apply to Office 365 Groups will also govern the groups created by applications (such as Teams).



In this chapter, we discussed basic concepts about SharePoint Online and Office 365 Groups. In the next chapter, we will begin learning about the SharePoint Online site and site collection management concepts.
