Google's new Apps Marketplace could give a significant boost to Web-based communication and collaboration software for businesses by creating a wide-ranging yet integrated virtual suite of heterogeneous cloud applications.

With Google Apps at the center of the galaxy of marketplace applications, businesses can craft a custom collaboration and communication suite featuring single sign-on and other integration points.

The Apps Marketplace will likely trigger the age-old argument of whether it's better to have a single-vendor collaboration suite or assemble "best of breed" applications from multiple vendors.

Google believes that by allowing Apps Marketplace applications to tie into the Google Apps platform through a variety of APIs (application programming interfaces) and open protocols, it can provide the best of both worlds.
