The Different Faces of Drupal Multi-Site
We have recently had a number of projects involving some form of multi-site installation. It is interesting to note that multi-site in most cases is different for each client. For instance, we have a credit bureau client that uses multi-site to offer their Fortune 500 banking clients access to credit score and history data on some 3 million businesses. They do this through a Drupal front end that integrates with a custom Web Service to provide accurate credit information on their banking clients.
