© 2009 IBM Corporation Mainframe Systems 2 What is cloud computing? A user experience and a business model Cloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model. An infrastructure management and services delivery methodology Cloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling.

© 2009 IBM Corporation Mainframe Systems 10 FSS company builds a Test cloud and improves productivity of personnel and ROI for the businesses Business Problem Solution Overview Lessons Learned Complex IT environments, lacking automation. This results in long lead times for requests, and high cost for deploying and managing environment. Little standardisation of configuration leading to quality issues and additional maintenance overhead. Want to improve audit results and IT compliance for development and test. Need to improve capacity without increasing cost Set scope around a process not around a function – focus on the people and the skills to drive rapid implementation. This is transformative and crosses organizational boundaries. Executive sponsor support is vital. Phased pilot, with first phase completed in Q408. Use TSAM as the cloud management solution (incl. service management) in a pilot. Manage the deployment of distributed WAS ND instances on zLinux, z/VM, DASD. Implement and prove a set of scenarios: Instantiation of a distributed WAS ND cluster running on zLinux. Increase capacity of a WAS ND cluster service instance. Delete a WAS ND cluster service instance. Tangible results from Pilot: Simplified – Requires less interaction with developers to get a new WAS ND Cluster. Faster time-to-market for developed apps. 100% consistent deployment of environment
