IBM introduced its first family of expert integrated systems called PureSystems. PureSystems include the PureFlex and PureApplication systems. PureFlex is an infrastructure system expert at optimizing resources, while PureApplication is a platform system expert at rapidly deploying and running applications. PureSystems are designed to provide the benefits of flexibility, simplicity, and agility while overcoming the challenges of time, expense, and shared dependence faced by other approaches.
