Microsoft Windows Server 2008 R2 Enterprise





Windows Server 2008 R2
builds on the award-winning foundation of Windows Server 2008, expanding existing technology and adding new features to enable organizations to increase the reliability and flexibility of their server infrastructures. New virtualization tools, Web resources, management enhancements, and exciting Windows 7 integration help save time, reduce costs, and provide a platform for a dynamic and efficiently managed data center. Powerful tools such as Internet Information Services (IIS) version 7.5, updated Server Manager and Hyper-V platforms and Windows PowerShell version 2.0 combine to give customers greater control, increased efficiency and the ability to react to front-line business needs faster than ever before. Windows Server 2008 R2 includes many enhancements that make this release the most robust Windows Server Web application platform yet. It offers an updated Web server role, Internet Information Services (IIS) 7.5, and greater support for .NET on Server Core.
Design goals for IIS 7.5 concentrated on improvements that enable Web administrators to more easily deploy and manage Web applications, that increase both reliability and scalability. Additionally, IIS 7.5 has streamlined management capabilities and provides more ways to customize your Web serving environment.

The following improvements to IIS and the Windows Web platform are included in Windows Server 2008 R2:

• Reduced Effort to Administer and Support Web-Based Applications
• Reduced Support and Troubleshooting Effort
• Improved File-Transfer Services
• Ability to Extend Functionality and Features
• Improved .NET Support
• Improved Application Pool Security
• IIS.NET Community Portal
Improvements to IIS and the Windows Web platform, which are included in Windows Server 2008 R2, include reduced effort to administer and support Web-based applications, enhanced security for Web-based applications, improved file-transfer services, the ability to extend the functionality and features for Web-based applications, and improved availability and performance for Web-based applications and services.
Windows Server 2008 with Hyper-V (formerly codenamed “Viridian”) will be released as a feature of Windows Server 2008 and is now available with Windows Server 2008 Enterprise. Microsoft also plans to release a standalone virtualization technology, Microsoft Hyper-V Server, which allows customers to virtualize multiple operating systems onto a single physical server.
Microsoft Windows Server 2008 is the most advanced Windows Server operating system yet, designed to power the next-generation of networks, applications, and Web services. With Windows Server 2008 you can develop, deliver, and manage rich user experiences and applications, provide a secure network infrastructure, and increase technological efficiency and value within your organization.
Windows Server 2008 builds on the success and strengths of its Windows Server predecessors while delivering valuable new functionality and powerful improvements to the base operating system. New Web tools, virtualization technologies, security enhancements, and management utilities help save time, reduce costs, and provide a solid foundation for your information technology (IT) infrastructure:



• Built for the Web

Windows Server 2008 comes with Internet Information Services 7.0 (IIS7), a Web server and security-enhanced, easy-to-manage platform for developing and reliably hosting Web applications and services. A major enhancement to the Windows Web platform, IIS7 includes a componentized architecture for greater flexibility and control. IIS7 also provides simplified management, powerful diagnostic and troubleshooting capabilities that save time, and comprehensive extensibility.
Internet Information Server IIS7 together with the .NET Framework 3.0 provide a comprehensive platform for building applications that connect users and data, enabling them to visualize, share, and act on information. Additionally, IIS7 plays a central role in unifying Microsoft's Web platform technologies—ASP.NET, Windows Communication Foundation Web services, and Windows SharePoint Services.



• Virtualization Built In

Microsoft Windows Server Hyper-V, the next-generation hypervisor-based server virtualization technology, allows you to make the best use of your server hardware investments by consolidating multiple server roles as separate virtual machines running on a single physical machine. You can also efficiently run multiple operating systems—Windows, Linux and others—in parallel on a single server. With virtualization built into the Windows Server 2008 operating system and simple licensing policies, it's now easier than ever to take advantage of the cost savings of virtualization.
Applications can also be efficiently virtualized using Windows Server 2008 centralized application access technologies. Terminal Services Gateway and Terminal Services RemoteApp allow easy remote access to standard Windows-based programs from anywhere by running them on a terminal server instead of directly on a client computer—without the need for a complicated VPN.



• Security

Windows Server 2008 is the most secure Windows Server yet. The operating system has been hardened to protect against failure and several new technologies help prevent unauthorized connections to your networks, servers, data, and user accounts. Network Access Protection (NAP) helps ensure that computers that try to connect to your network comply with your organization's security policy. Technology integration and several enhancements make Active Directory services a potent unified and integrated Identify and Access (IDA) solution. And Read-Only Domain Controller (RODC) and BitLocker Drive Encryption allow you to more securely deploy your AD database at branch office locations.



• A Solid Foundation for Your Business Workloads

Windows Server 2008 provides a solid foundation for all of your server workload and application requirements while being easy to deploy and manage. The all-new Server Manager provides a unified management console that simplifies and streamlines server setup, configuration, and ongoing management. Windows PowerShell, a new command-line shell, enables administrators to automate routine system administration tasks across multiple servers. Windows Deployment Services provides a simplified, secure means of rapidly deploying the operating system via network-based installations. And Windows Server 2008 Failover Clustering wizards, and full IPv6 support plus consolidated management of Network Load Balancing, make high availability easy to implement even by IT generalists.
Finally, the new Server Core installation option of Windows Server 2008 allows for installation of server roles with only the necessary components and subsystems without a graphical user interface. Fewer roles and features means minimizing disk and service footprints while reducing attack surfaces. It also enables your IT staff to specialize according to the server roles they need to support.
