What is Virtualization?

Virtualization lets a single physical resource (such as a server, an operating system, an application or storage device) appear as multiple logical resources; or making multiple physical resources (such as storage devices or servers) appear as a single logical resource

 

Why Would a Company Virtualize?

  1. Get more out of your existing resources: Pool common infrastructure resources and break the legacy “one application to one server” model with server consolidation.
  2. Reduce datacenter costs by reducing your physical infrastructure and improving your server to admin ratio: Fewer servers and related IT hardware means reduced real estate and reduced power and cooling requirements. Better management tools provided by Microsoft, allows your organization to improve your server to admin ratio so personnel requirements are reduced as well.
  3. Increase availability of hardware and applications for improved business continuity: Securely backup and migrate entire virtual environments with no interruption in service. Eliminate planned downtime and recover immediately from unplanned issues.
  4. Gain operational flexibility: Respond to market changes with dynamic resource management, faster server provisioning and improved desktop and application deployment.
  5. Improve desktop manageability and security: Deploy, manage and monitor secure desktop environments that users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC.

 

OTHER BENEFITS OF VIRTUALIZATION

Partitioning one physical server into several virtual servers, or machines.

Each virtual machine can interact independently with other devices, applications, data and users as though it were a separate physical resource.

Different virtual machines can run different operating systems and multiple applications while sharing the resources of a single physical computer.

Each virtual machine is isolated from other virtualized machines, if one crashes, it doesn’t affect the others

Why is virtualization such a big deal? A lot of people understand, and they think it's about saving money, it's about saving power, it's about green IT, it's about space, and that's certainly true. But in our perspective, it's much, much bigger than that, and people are just now beginning to understand that. We think that there's a major transformation taking place in IT. This major transformation that's been taking place for years is starting to accelerate, and we believe that virtualization is a major enabler and catalyst of that transition that's taking place.” Tom Bittman, Gartner VP and Chief of Research of Infrastructure and Operations, at Microsoft’s Virtualization Launch Event ( SCROLLING

    Desktop Virtualization

    Desktop Virtualization is the technology of accessing virtual desktops on a central repository. Clients access their virtual desktops using traditional technologies such as thin clients and Microsoft’s Virtual PC application. Through Microsoft’s Desktop Virtualization solution and MBC’s sound expertise, organizations can expect to see the following benefits:

    bullet

    Reduce their Total Cost of Ownership (TCO) in your desktop infrastructure

    bullet

    Increased business agility in rapid provisioning of desktops

    bullet

    Enable anywhere access

    bullet

    Improved security and compliance

    Three desktop virtualization technologies which MBC offers are:

    bullet Virtual Desktop Infrastructure (VDI)
    bullet Microsoft Enterprise Desktop Virtualization (MED-V)
    bullet Application Virtualization (APP-V)

     

    What is VDI?

    Microsoft’s VDI is an infrastructure design of desktop virtualization that employs a full desktop computing experience to users at lower costs than a traditional PC environment. This means that users’ desktops, applications and data reside on servers running Windows Server 2008 with Hyper-V, where they can be managed more easily and deployed to a wide variety of clients ranging from rich clients (standard desktop PCs) to thin clients such as diskless workstations.

     

    Benefits of VDI

    bullet Management - In a typical corporate infrastructure, desktops are managed using remote software push technology. It is very difficult to manage hundreds of desktops as you are well aware if you administer desktops in your corporate infrastructure. Using technology such as virtual desktop infrastructure (VDI) allows you to have central management of all your desktops and really control what is being installed and used on the desktops. Deployment of virtual desktops is lightning fast as opposed to using imaging technologies.
    bullet Security - Security is a key factor in rolling out VDI. With VDI, you have greater control of how secure your desktop is. You can lock down the image from external devices or prevent copying data from the image to your local machine. Remote users or road warriors also benefit as sensitive data is stored on the server in the data center and not the device. If the device is stolen, the information is protected.
    bullet OS migrations - Prior to VDI, IT administrators would have to look at their equipment and most likely upgrade hardware, memory, disk space, etc. in order to roll out a new operating system. With VDI, an image from a central location can just be pushed out to the group of managers.
    bullet VDI image - A library of VDI images can be created to meet all of your company needs. If your company is seasonal, you can have extra images to handle the increased employee traffic. If your organization uses third-party vendors/contractors/consultants, you can use secure/encrypted locked down images to allow them to work in your environment.
    bullet Snapshot technology - With VDI, you have the ability to roll back desktops to different states. This feature allows you to provide significant flexibility to your end users.
    bullet Go green - A thin client VDI session will use less electricity than a desktop computer.  Using VDI is a way to reduce your carbon footprint on our planet and save your company money in power costs.

     

    What is MED-V?

    Microsoft Enterprise Desktop Virtualization (MED-V) is a desktop virtualization technology that builds upon the highly popular and easy-to-use Microsoft Virtual PC 2007. Microsoft Virtual PC is a free software product that allows users to run virtual machines directly on their desktop computers. Each virtual machine (VM) consists of a guest operating system, which is another instance of an operating system running concurrently with the host operating system, and is independent of the host hardware or setup.

     

    Benefits of MED-V

    bullet Legacy OS and Application Support - MED-V will allow end users to run multiple, separate operating systems (e.g., Windows XP, Windows Vista, or Windows 2000) all on one physical desktop, so users can work with legacy applications that are not supported on the latest operating system versions.
    bullet Easier OS and Application Migration – MED-V allows phased software migration, as a new OS (e.g., Windows Vista or, in future, Windows 7) or a new application can run side-by-side with existing legacy software (e.g., Windows XP) without any conflicts, eliminating many migration costs and effort, and smoothing the migration
    bullet Multiple Environment Support – MED-V allows users to run multiple operating environments (e.g., Windows XP and Windows Vista) on a single physical desktop, so they can more effectively multi-task (even with multiple copies of single-user applications) or run multi-tier development environments without additional hardware.
    bullet Faster Workforce Integration for M&A – when mergers and acquisitions occur, acquired employees can immediately be given a standard corporate image (e.g., across a LAN or VPN), which will run alongside their existing system, providing standardized applications and policy-compliant access for both the new and previous corporate environments, without waiting for a completely new desktop system.
    bullet Reduced Cost of Management – administrators can deploy highly standardized and centrally managed virtual desktops, and manage a single image instead of hundreds of unique builds on any system – in the future, even on employees’ or contractors’ personal systems – removing hardware dependencies and reducing IT management costs while allowing personalization to improve productivity
    bullet Ease of Deployment and Update – a new or updated MED-V virtual desktop can be supplied to any end user quickly and easily, via a network download, on a removable media, and loaded in minutes, resulting in fast, simple deployments and upgrades for corporate desktop images and applications.

     

    What is App-V?

    Microsoft Application Virtualization (App-V) provides the ability to deliver applications to end users without actually installing the applications on their client computers. The applications are “packaged” so they run within a self-contained virtual environment (cached) or “sandbox” on client computers.

     

    Benefits of App-V

    bullet Application Isolation - Run incompatible applications side-by-side, at the same time and with minimal regression testing against one another.
    bullet Improved Provisioning - Accelerated application deployment, through on-demand application streaming.
    bullet Improved Auditing - Implement the security principle of least privilege by removing the requirement for end-users to have Administrator privileges in order to run poorly written applications.
    bullet Improved IT Control - Enterprises can easily track license usage. Application usage history can then be used to save on license costs.
    bullet Improved End User Agility - Allows applications to be copied to portable media and then imported to client computers without need of installing them.

     

    Virtualization Management

    MBC recommends and provides the use of Microsoft System Center Virtual Machine Management (SCVMM) 2008 for managing your organization’s physical and virtual infrastructure. Virtual Machine Manager (VMM) helps enable centralized management of physical and virtual IT infrastructure, increased server utilization, and dynamic resource optimization across multiple virtualization platforms. It includes end-to-end capabilities such as planning, deploying, managing, and optimizing the virtual infrastructure.

     

    The benefits your enterprise can achieve by deploying this tool are as follows:

    bullet Centrally creates and manages virtual machines across the entire datacenter
    bullet Easily consolidates multiple physical servers onto virtual hosts
    bullet Rapidly provisions and optimizes new and existing virtual machines
    bullet Performance and Resource Optimization (PRO) enables the dynamic management of virtual resources through management packs that are PRO enabled. As an open and extensible platform, PRO encourages partners to design custom management packs that promote compatibility of their products and solutions with PRO’s powerful management capabilities.
