There should be a contract that allows for a trial period with some escalating terms so the customer can gain confidence and "sign up for more." Best practices is a term that can vary greatly depending on what is to be offered and certainly is more involved than can be answered here. Suffice it to say that is represents creating a template for storage service that can scale with the customer but is adaptable enough to handle the expected variations that each customer will have. The service must be flexible but yet still capable of gaining the economies of scale. Additionally it must have proven isolation for each customer so they feel that they are the only customer with no other customer impacting or impinging on their level of service.
Adding value is in the efficiency of the operation, the reliability of the access to data and the seamless scaling without impacting the business to meet ongoing capacity demands.
