IBM Systems Magazine, Mainframe digital edition - September/October 2009 - (Page 37) IBM study reveals the System z10 provides a cheaper, easier-to-manage cloud solution BY SCOTT A. BAIN Editor’s Note: This article is based in part on an internal study, conducted by Scott A. Bain, Fehmina Merchant, Innes Read and John J Thomas. T o d a y ’s e c onom y r e q u i r e s a n agile business model, yet many compa n ies a re st r ugg li ng w it h an increasingly costly and rigid IT infrastructure due to high maintenance, n e t wo r k , o p e r a t i o n a l a n d m a n a ge m e n t expenses. As a result, line-of-business units are beginning to go outside the data center to public cloud providers like Amazon hoping to lower costs and improve responsiveness. To a v o i d d i s i n t e r m e d i a t i o n , I T m u s t re-invent the data center and move toward a more Dynamic Infrastructure*—one that uses v i r t ua l i zat ion a nd con sol idat ion to he lp improve utilization levels and reduce power consumption, and one that embraces a private cloud model to dynamically provision IT services in minutes or hours, rather than months. In this article, I’ll examine the total cost of ownership (TCO) for a Dynamic Infrastructure built around private cloud services, comparing it to public cloud a lter nat ives, as well as SEPTEMBER/OCTOBER conventional one-application-per-distributedserver models. The results show private cloud implementations built around larger, virtualized, x86 and System z* servers can be up to 75 percent less expensive than public cloud options over a five-year period and around 80 percent less than a distributed stand-alone-server approach. The Results recent inter nal st udy of I BM’s nearly 4,000 distributed servers showed annual operational costs attributed to each server was more than $34,000, with almost 90 percent due to sof t ware maintenance and systems administration. It stands to reason that reducing the number of physical servers to fewer, larger and more capable machines can greatly reduce these costs. The virtues of virtualization and consolidation to accomplish this have been well publicized. What has proven to be more elusive, however, is the quantification of these benefits. How many workloads can be consolidated onto a given platform while maintaining acceptable service-level agreements (SLAs)? Which platform provides the greatest economy of scale, producing the lowest cost per virtual machine image or 2009 ibmsystemsmag.com/mainframe 37 A http://www.ibmsystemsmag.com/mainframe Table of Contents for the Digital Edition of IBM Systems Magazine, Mainframe digital edition -
