- Increase server utilisation: move away from “one server, one role” mentality Reduced data centre costs extends beyond server hardware to foot print, power, network, cooling etc & licensing Backup simplification as variables such as operating system, system state, data and application configuration can be reduced to backing up the files on the host that represent the virtual machines and restores can be readily accomplished Increased security over single server/multi-tier workload server consolidation Development/Testing environment: Separation of security contexts; developers work with a different account with elevated rights in the VM and work with a 'standard' low privilege account on the physical workstation. Also the VM's are positioned in a dedicated developer forest/domain separated from the production forest. Separation of support; the developer notebooks can now be provided with a standard image on top which Vmware hosts the VM's. So they can treat the VM's as a standard application with minimal impact on their standard support organization. Support for multiple development environments; the infrastructure is always the same but developers can use multiple VM's. For example 1 VM with Visual Studio 2003 on Win XP and also a VM with Visual Studio 2005 on Windows 2003. Also developers can simulate a server environment by configuring the VM's locally appropriately and using a representative test-client in a VM. Thus providing an early stage test environment. Greater control for support organization; when a VM breaks they can easily provide a new one or on demand Offshore integration by packaging and shipping environments – more cost effective than building and maintaining offshore infrastructures 04/02/10 22:49 © 2004 Microsoft Corporation.

- Treat virtual the same as physical – it should essentially be invisible. If you don’t have good tools & processes for the physical environment, these problems will re-surface in the virtual environment (likely multiplied as virtual server sprawl will out pace physical sprawl!). Get a grip of machine life cycle management, virtial machines are not a magic wand! 04/02/10 22:49 © 2004 Microsoft Corporation. All rights reserved.

- By taking a generic approach – server management is holistic. Really just adding tools & process (in addition to those for physical) to manage the environment Introducing virtualisation simplifies and accelerates some parts: rapid build & save state (safe state the environment not really practical in a physical environment). Differencing disks mean you maintain fewer “images” of servers 04/02/10 22:49 © 2004 Microsoft Corporation. All rights reserved. This presentation is for informational purposes only.

- In September 2005, a team from Accenture’s Infrastructure Outsourcing organization needed to test a hosted service offering that included a new third-party desktop management application. The solutions consisted of an infrastructure lab to build, and later manage, model client infrastructures that included the following systems: Four application servers running a combination of the Microsoft® Windows Server® 2003 Enterprise Edition operating system and the Microsoft Windows® 2000 Server operating system Microsoft SQL Server™ 2000 A domain controller with the Active Directory® service Additionally, developers required five client environments running different versions of: Microsoft Windows NT® Workstation operating system version 4.0 Microsoft Windows 2000 Professional Windows XP Professional with Service Pack 1 and Service Pack 2 Red Hat Linux Engineers had four weeks to build the environments. Neither purchasing nor leasing five new servers and five workstations was a cost-effective option because the team only needed the systems for a few months. The solution used Virtual Server 2005 R2 for the server environment and Virtual PC 2004 for the client systems. By building virtual machines, the Accenture infrastructure lab met its goal one week ahead of schedule, which enabled more extensive testing. What’s more, compared to building a traditional test environment, building virtual machines requires less physical hardware. However, the benefits of this approach reach far beyond a single project. As a result of using Virtual Server and Operations Manager in the department’s test lab, Accenture has significantly reduced its total cost of ownership, accelerated the setup of model environments by more than 200 percent, streamlined system administration, improved IT responsiveness with a smaller staff, and enabled more robust testing of products and service offerings. 04/02/10 22:49 © 2004 Microsoft Corporation.
