Ahold, an international retailer an employer of over 222,000 employees loves Google Sites! Why?
Within hours they could develop and deploy Google Sites to deploy the relevant procedures to its stores to know what to do for Hurricane Sandy. Since Ahod did not house the data centres and the Google distributes the Google Sites across the globe it did not matter where the sites were: they contniued to work.
Since Ahold uses Google Apps for Business it found that anyone could make Google Sites so Ahold could allow its employees to make self-service portals and take its old portals and use Google Sites to allow all to access.
