Microsoft launched Office 365 (O365) in June 2010, including SharePoint 2010 Online, as an update to its existing Business Productivity Online Services (BPOS) suite that offered SharePoint 2007 Online. But what is SharePoint?
SharePoint is a web-based platform and so being hosted in the cloud means that it provides a highly accessible platform from anywhere on the Internet -- securely. The key benefit to the platform is that it provides a common framework for solutions to build on, rather than each solution being built by different teams using different frameworks, which subsequently leads to maintenance and operational issues.
