Windows Server 2008 R2 Standard provides organizations with the ability to deliver rich Web-based experiences efficiently and effectively, with improved administration and diagnostics, advanced development and application tools, and lower infrastructure costs.

Internet Information Services 7.5
Windows Server 2008 R2 Standard is a powerful Web application and services platform. The Internet Information Services (IIS) 7.5 in Windows Server 2008 R2 Standard delivers a completely modular, extensible Web server with expanded application hosting, while retaining excellent compatibility and solving key customer challenges.

Virtualization
Many organizations find that patch management, resource utilization, maintenance costs, and server sprawl are among their biggest challenges. Server virtualization technologies, including Windows Server Hyper-V and enhancements to Remote Desktop Services, can help meet all of these challenges by helping you consolidate your resources and realize significant infrastructure and management cost savings.

Windows Server Hyper-V
Windows Server 2008 R2 Hyper-V is the hypervisor-based virtualization feature included as a role of Windows Server 2008 R2. It contains everything needed to support machine virtualization. Hyper-V enables IT organizations to reduce costs, to improve server utilization, and to create a more dynamic IT infrastructure. Hyper-V provides the greater flexibility because of dynamic, reliable, and scalable platform capabilities combined with a single set of integrated management tools to manage both physical and virtual resources, which enables you to create an agile and dynamic datacenter and progress toward achieving self-managing dynamic systems.

Remote Desktop Services
Remote Desktop Services in Windows Server 2008 R2 Standard provides a security-enhanced, easy-to-manage platform for delivering access to centrally managed applications and resources from the Internet by using HTTPS; you do not need to provide access through a virtual private network (VPN) or by opening unwanted ports on firewalls.

Application Virtualization
Application virtualization separates the application configuration layer from the operating system. It enables applications to run on clients—including desktops, servers, and laptops—without being installed, and allows applications to be administered from a central location. This enables you to run applications that otherwise may not be able to coexist on the same server.
Improved Data Center Power Consumption and Streamlining Management

The ongoing management of servers in the data center is one of the most time-consuming tasks facing IT professionals today. Any management strategy you deploy must support the management of both your physical and virtual environments. To help with this problem, Windows Server 2008 R2 has new features to reduce the ongoing management of Windows Server 2008 R2 and to reduce the administrative effort for common day-to-day operational tasks.

Improved data center power consumption management
With the proliferation of physical computers in data centers, power consumption is of paramount importance. In addition to the cost-saving associated with reducing power consumption, many data centers are constrained by the number of computers they can support in their data center by the actual power available to the data center. Therefore reducing your power consumption also allows you to support more physical computers while using the same amount of power, or less power, than before.

Improved Management of File Services
Storage is no longer a marginal expense. Nor is managing storage any longer simply about volume and availability; organizations need to manage their data more effectively as well as more efficiently. Only by gaining insight into their data can companies reduce the cost of storing, maintaining, and managing data. Only by enforcing company policies and knowing how storage is utilized can administrators efficiently use their storage and mitigate the risks of leaking data. The next frontier for administrators is to be able to manage data based on business value. The Windows File Classification Infrastructure (FCI) in Windows Server 2008 R2 provides insight into your data to help you manage your data more effectively, reduce costs, and mitigate risks.

Improved remote administration
Remote administration of server computers is essential to any efficient data center. It is very rare that server computers are administered locally. Windows Server 2008 R2 introduces a number of improvements in remote administration, including improved remote management through graphical management consoles and improved remote management from command-line and automated scripts.

Reduced administrative effort for administrative tasks performed interactively
Reducing administrative effort for day-to-day administrative tasks is another key design goal for Windows Server 2008 R2. Many of the management consoles used to manage Windows Server 2008 R2 have been updated or completely redesigned to help reduce your administrative effort. Some of the prominent updated and redesigned management consoles are listed in the following table with descriptions of the improvements.

Enhanced command-line and automated management by using PowerShell version 2.0
The PowerShell 1.0 scripting environment was shipped with Windows Server 2008 RTM. Windows Server 2008 R2 includes PowerShell 2.0, which offers a number of improvements over version 1.0, including the following:
- Improved remote management by using PowerShell remoting;
- Improved security for management data, including state and configuration information, by using constrained runspaces;
- Enhanced GUIs for creating and debugging PowerShell scripts and viewing PowerShell script output by using Graphical PowerShell and the Out-GridView cmdlet;
- Extended scripting functionality that supports creation of more powerful scripts with less development effort;
- Improved portability of PowerShell scripts and cmdlets between multiple computers.

Improved identity management
Identity management has always been one of the critical management tasks for Windows-based networks. The implications of a poorly managed identity managed system are one of the largest security concerns for any organization. Windows Server 2008 R2 includes identity management improvements in the Active Directory Domain Services and Active Directory Federated Services server roles.

Improved compliance with established standards and best practices.
Windows Server 2008 R2 includes an integrated Best Practices Analyzer for each of the server roles. The Best Practices Analyzer creates a checklist within Server Manager for the role, which you can use to help perform all the configuration tasks.

Scalability and Reliability
Windows Server 2008 R2 is capable of unprecedented workload size, dynamic scalability, and across-the-board availability and reliability. A host of new and updated features contribute to this including:
Leveraging sophisticated CPU architectures
Windows Server 2008 R2 is the first Windows operating system to be offered for only 64-bit processors. With customers being unable to purchase a 32-bit server CPU for over two years, the performance and reliability advantages to moving to this architecture were too beneficial to ignore.

Increased operating system componentization
Microsoft introduced the concept of server roles to allow server administrators to quickly and easily configure any Windows-based server to run a specific set of tasks and remove extraneous OS code from system overhead. Windows Server 2008 R2 further extends this model with support for more roles and a broadening of current role support, like the addition of ASP.NET within IIS 7.5. Roles have been refined and feature sets redefined as customers have expressed desires for certain capabilities in popular scenarios.

Improved performance and scalability for applications and services
Another key design goal was to provide higher performance for Windows Server 2008 R2 running on the same system resources as previous versions of Windows Server. In addition, Windows Server 2008 R2 supports increased scaling capabilities that allow you to support greater workloads than ever before. Windows Server 2008 R2 features that improve performance and scalability for applications and services.

Improved Storage Solutions
The ability to quickly access information is more critical today than ever before. The foundation for this high-speed access is based on file services and network attached storage (NAS). Microsoft storage solutions are at the core of providing high-performance and highly available file services and NAS. The release version of Windows Server 2008 introduced many improvements in storage technologies. Windows Server 2008 R2 includes additional improvements that enhance the performance, availability, and manageability of storage solutions.

Improved Protection of Intranet Resources
The Network Policy Server (NPS) is a Remote Authentication Dial-In User Service (RADIUS) server and proxy and Network Access Protection (NAP) health policy server. NPS evaluates system health for NAP clients, provides RADIUS authentication, authorization, and accounting (AAA), and provides RADIUS proxy functionality.

Windows Server 2008 R2 Standard is a robust and reliable foundation on which to develop, deliver, and manage rich user experiences and applications.
