Overview of SharePoint Online
Microsoft Launches Office 365, a Cloud-Based Collaboration Product This Month Office 365 is based on the SharePoint Online service, which is a cloud-based version of SharePoint 2010.
This article discusses the features of SharePoint Online for users and developers. In terms of capabilities, SharePoint Online almost coincides with SharePoint 2010, but there are also differences that will be discussed below.

Microsoft Office 365 is a suite of collaboration and communication products.
Administering the solution is simple and convenient.

Office 365 can be used by organizations of any size, for more information about subscription plans, see the Office 365 Plans page .
SharePoint Online is a service in the cloud, with Microsoft administering the servers and solutions.
After authorization on a public website, users get to the group’s website (Fig. 2).

In the top link bar you can see the Website (we are talking about a public website), when you go to which you can see all its pages (Fig. 3). In this case, you can add or delete pages, as well as edit them directly in the browser.

In SharePoint Online, you can create sites to solve various problems:
Thanks to Office Web Apps, you can view Office documents (even versions 97-2003), but you can only edit documents created in Office 2010.
It’s convenient that you don’t need to configure rules for crawling content, since everything has already been done for us. To control the indexing of documents in the library settings, you can use the Allow items from this document library to appear in search results option.
Depending on the selected subscription, Excel services, Access services, Visio services are available to users. PerformancePoint is currently not available in all subscriptions.
In addition, when working with SharePoint Online, you can use SharePoint Workspace, an application included in Office 2010 that allows you to store a local copy of the contents of the portal.
It should be noted that there is no Central Administration; instead, you can use Site Settings (Fig. 4).

Consider developer options in SharePoint Online. As with SharePoint 2010, there are the following areas.
The development process for SharePoint Online is similar to the development for SharePoint 2010. Development in Visual Studio 2010 is for the local instance, after which the solution is uploaded to the cloud in the Solution Gallery.
SharePoint Online is based on SharePoint 2010, but they do not completely coincide in functionality (a brief comparison can be found in Table 1).
Table 1 Feature comparisons
In SharePoint Online, you can create solutions with the Site and Web realms. This is due to the fact that the farm hosts sets of sites from different customers. The restriction on the development of only sandboxed solutions is based on security considerations so that you cannot go outside your own set of sites or get permission to run in a farm with administrator privileges.
As you can see from the table, most of the tools are supported in SharePoint Online. However, there is no support for Business Connectivity Services (BCS) and external lists. It remains to be noted that BCS support is planned in a future version. Also, due to the limitations of sandboxed solutions, you cannot call web services outside of SharePoint Online.
SharePoint developers can use SharePoint Online to create solutions in the cloud, thus expanding their business. In doing so, consider what is supported in SharePoint Online and what is not.
If we talk about novice developers, you need to understand isolated solutions, a client object model and declarative workflows.
