As has been the case with its other components, Apps is fetching this latest application from Google's roster of consumer services -- in this case the Google Groups service -- and giving it the necessary tweaks to make it suitable for a workplace setting, like IT administration controls.

"We're adding a key piece of functionality that really bolsters our enterprise messaging functions," said Rajen Sheth, Google Apps senior product manager. "This is also a great example of the concept of consumerization of enterprise and of giving power to the users to do things they've typically had to rely on IT to do for them."

The Groups application, which will go live on Wednesday, allows for the creation of mailing lists for group members, but also lets users embed other Apps components into the forums, including calendars, word-processing documents, presentations, videos and spreadsheets. Content posted to the forums is indexed in full text and searchable.

Groups is available in the Education and Premier editions of Apps, but not in the Standard edition. Apps administrators need to activate Groups for their domain, at which point end-users can create forums in an ad-hoc fashion without IT intervention. The IT department can establish policies and access rights for groups. Group owners also can manage certain settings for their forums and lists.

Google, the undisputed leader in the consumer search-engine market, is intent on becoming a major player in enterprise software, and Google Apps is arguably its best-known product for workplaces, an up-and-coming rival to established communication and collaboration suites from the likes of Microsoft and IBM's Lotus.
