If we stop and take stock of an organization's requirements for optimal resource utilization; high levels of both reliability and availability; and still achieve the goal of simplicity and cost reduction, it is clear that IT decision-makers must consider all of the reasonable alternatives available to them.
Mainframes and midrange systems from suppliers, such as IBM, can’t be merely thought of as a legacy of the past. They have not only been the source of many of today's innovations, they continue to be seen as holding advantages over other platforms – and these advanced, mature virtualization capabilities allow users to drive higher utilization. The energy and cost savings associated with fewer wasted compute cycles shouldn’t be ignored. Suppliers, such as IBM, are not resting on the history of their successes; they are pushing technology forward at a rapid pace. Some of these innovations will likely later move into the world of industry standard systems as well.
Regardless of whether a workload is designed for traditional batch execution, highly interactive client-server, Web-based or even cloud computing, these environments should be considered.
