As companies do business in more time zones and increasingly 24x7 online it increases availability requirements including the need to minimize and/or eliminate planned downtime for maintenance. The information platform of the future needs to deliver the scalability and availability to meet these requirements. Compliance and Risk Management The larger the number of regions in which you do business the greater the number of regulations with which you need to be compliant. Increasing regulatory requirements and growing volumes of data of all types from documents to scanned images to core relational data continues to increase the challenges around compliance and risk management over the full lifecycle of data from birth to archival. The information platform of the future needs to simplify compliance for all your data. Right Information at the Right Time It’s no longer good enough to simply keep the business running. There are much higher expectations of leveraging data to create competitive advantage.. As it becomes more and more feasible to capture, store
