1. INTRODUCTION
Mobile computing has been growing in popularity over several years, while the mobile telephone has evolved into a ubiquitous device used by the majority of people today. The increasing capabilities of mobile phones, and the more universal coverage and higher bandwidth networks available to them, has meant that the combination of mobile computing and the phone has become a very persuasive and appealing platform for both consumer and enterprise applications.
Windows Phone 7 brings all the advantages of a standardized platform and a consistent developer experience to the Microsoft platform for devices from many different manufacturers. It is not a replacement for Windows Mobile, which continues to provide a powerful platform for a wide range of devices and application scenarios. Instead, Windows Phone 7 is a brand new mobile device that incorporates a comprehensive set of features necessary to build applications that satisfy the needs of business and consumers, to allow developers to easily create powerful interactive and attractive applications, and to reuse their skills and knowledge of existing modern development environments, such as the Microsoft Silverlight® and the Microsoft XNA® development platforms
3. Targeting Windows 7 Phone with Silverlight
Virtualization is a huge part of today’s data centers. The operating efficiencies offered by virtualization allow organizations to dramatically reduce the operations effort and power consumption.
Virtualization is a key enabling technology that can be leveraged to achieve business benefits. Server Virtualization technology enables customers to run multiple operating systems concurrently on a single physical server, where each of the operating systems runs as a self-contained computer.
Today there is more pressure than ever on IT with shrinking budgets, rapidly changing technologies and increasing security issues. As companies grow, their IT infrastructures grow along with them. But more often than not, the pace of that growth is uneven, driven as much by the conditions under which they operate as the model they aspire to. IT is being increasingly viewed as a key value generator for most organizations, and the focus for IT is shifting from merely keeping the business up and running to being an engine to drive responsiveness and agility across the organization.
3. a. BENEFITS
IT organizations today are under incredible pressure to deliver more value to their business customers — and typically with little or no increase in budgets.
Optimizing the use of physical IT assets is becoming imperative as data
Centers reach their capacity for power and space. Microsoft recognizes that the problem intensifies for companies whose servers run at very low utilization. Server utilization rates of less than 5 percent are not uncommon, and many customer usage rates fall into the 10 percent to 15 percent range. Many of these challenges, shared between server administrators and developers, can be addressed with the help of Microsoft’s virtualization solutions.
Machine virtualization technology is used to consolidate multiple physical machines onto a single physical machine. Virtualization can also be used to re-host legacy environments, especially as older-generation hardware becomes more difficult and costly to maintain. And because software is abstracted from the hardware, virtualization is a good solution for disaster recovery environments as well.
Hyper-V provides software infrastructure and basic management tools in Windows Server 2008 that you can use to create and manage a virtualized server computing environment. This virtualized environment can be used to address a variety of business goals aimed at improving efficiency and reducing costs. For example, a virtualized server environment can help you:
• Reduce the costs of operating and maintaining physical servers by
Increasing your hardware utilization. You can reduce the amount of
Hardware needed to run your server workloads.
• Increase development and test efficiency by reducing the amount of
Time it takes to set up hardware and software and reproduce test
Environments.
• Improve server availability without using as many physical computers
As you would need in a failover configuration that uses only physical
Computers.
• Increase or reduce server resources in response to changes in demand.
As a key part of any server consolidation strategy, Microsoft’s virtualization solutions increase hardware utilization and enable organizations to rapidly configure and deploy new servers with the following key benefits:
• Efficient use of hardware resources. Virtual machine isolation and
Resource management enables multiple workloads to coexist on fewer
Servers, allowing organizations to make more efficient use of their
Hardware resources. With advancements in server hardware with 64-
Bit technology, multiprocessor and multi-core systems, virtualization
Provides an easy way to optimize hardware utilization.
• Enhanced administrative productivity and responsiveness.
Hyper-V enables IT organizations to enhance their administrative
Productivity and rapidly deploy new servers to address changing
Business needs. Easy integration into existing server management
Tools, such as System Center Operations Manager and sophisticated
Tools such as System Center Virtual Machine Manager (SCVMM)
Windows Server facilitates management of Windows virtual machines. The ability to consolidate workloads in a hardware-agnostic environment and an integrated physical and virtual IT management framework enables administrators to lower operational costs and create more agile datacenters.
• Well-supported server virtualization solution. Virtual Server 2005
R2 is extensively tested and supported by Microsoft in conjunction with
its server operating systems and applications. Hence Virtual Server
2005 R2 is a well-supported virtualization solution both within Microsoft and across the broader ISV community. With Hyper-V being an integral component of Windows Server 2008 and Virtual Machine Manager being part of the System Center family, you can be assured that the virtualization solutions from Microsoft will also be extensively tested and well-supported. The use of a common virtual hard disk (VHD) format ensures investment protection for all the virtual machines
created for Virtual Server with a transparent migration path to Hyper-
• A key deliverable for Microsoft’s Dynamic Systems Initiative.
As a part of the DSI, Microsoft’s industry wide effort to dramatically
simplify and automate how businesses design, deploy and operate IT
systems to enable self-managing dynamic systems, Microsoft is
providing businesses with tools to help them more flexibly utilize their
hardware resources. Virtual Server 2005 R2, Hyper-V, and Virtual
Machine Manager are key examples of how Microsoft is continuing to
deliver technology that results in improved server hardware utilization
and provides for more flexible provisioning of data center resources
