Google's deal with Taylor Woodrow is a landmark case in its quest to take on Microsoft in the enterprise space. Before Taylor Woodrow, few large companies were prepared to acknowledge using its hosted applications technology.
Taylor Woodrow says it will save around £1m by transferring its users to Google Apps, due to the fact it can cut back on on-site infrastructure including servers and associated software.
Though the firm will retain the use of Microsoft Office, at least for the time being, it has given staff full use of Google Apps Premier Edition, which includes email, word processing, spreadsheet and presentations applications.
Taylor Woodrow has also deployed Google Message Discovery, which provides email security, content policy management and email discovery and archiving services.
"The mobility, coupled with the speed of rollout, the lack of a requirement for a physical infrastructure and the pace of new product development is very beneficial," said Rob Ramsay, Taylor Woodrow's director of IT.
"Ensuring that all our emails are protected from threats and stored correctly is something that is important to our business operations," he added.
As well as targeting Microsoft with its Google Apps portfolio, Google is trying to increase its presence in the security market.
It acquired security firm Postini last year, which led to the release of Google Web Security for Enterprise six weeks ago.
