Google said that Italian fashion house Roberto Cavalli is making the switch to Google Apps in a phased migration for 500 users.

Phase one of the project will see Roberto Cavalli implementing Google Apps Premier Edition that enables the company to move across from the systems currently used by the group to a single Gmail system, while keeping the robertocavalli.it/com domain.

This migration is expected to result in considerable cost savings for the group as multiple email servers, which were either maintained internally or outsourced to an external provider, will no longer be required.

Phase two will see the company adopting Google Sites, which the staff will use as an easily accessible, searchable image repository for the fashion designer’s picture archive.

Google said that the Italian fashion house is also planning to use Google Video to upload catwalk videos, making them available in real-time to all of Roberto Cavalli’s boutiques.

This project will use another feature of Google Apps, Google Video, which acts like a private version of YouTube that only members of the corporate domain can access. They will be able to upload, download, and share up to 3GB of videos per user account.

Google Apps Premier Edition offers enterprise version of Gmail, Google Calendar a suite of collaboration products including Google Docs, Google Sites and Google Video for Business.

The company said that Google Docs allows users to create and share documents, presentations and spreadsheets in real-time. Google Sites facilitates to create website easily, while Google Video for Business helps companies make content and communication more personal, visual and engaging.
