Infrastructure Roles
the infrastructure roles provide the major services for clients. Following are the eight
Active Directory roles that can be installed in Server 2008:
- Terminal Services
- Fax Services
- Print Services
- File Services
- Hyper-V
- UDDI Services
- Web Server (IIS 7)
- Windows Deployment Services
- Terminal Services Terminal Services in Windows Server 2008 provides technologies that
enable users to access Windows programs that are installed on a terminal server or to access
the Windows desktop itself from almost any computing device. Originally designed as a thinclient
terminal to present a working desktop to users, Terminal Services now delivers applications
using this same technology, often referred to as remote desktop, remote desktop
connection, or remote desktop protocol. Along with application and desktop presentation,
Windows Server 2008 allows administrators to publish these services to the Internet using
Secure Sockets Layer, or https. This is an excellent security alternative, as administrators have
been wary for years of opening TCP port 3389, the Terminal Services default port assignment,
to the Internet.
- Fax Services The Fax Services role in Windows Server 2008 allows administrators to create
a fax gateway on their network. This gateway allows clients to send, receive, and manage faxes.
- Print Services The Print Services role in Windows Server 2008 allows you to create
networked printer resources for clients. Also, it provides a central administrative point for
printer management. You install the Print Services role in Activity .
- File Services The File Services role allows you to share and manage file resources on a network.
It includes technologies such as the distributed file system, EFS, and the core functionality
of creating network file shares. You install the File Services role in Activity .
- Hyper-V Hyper-V is the newest virtualization technology from
Microsoft. It allows you to deploy multiple virtual machine instances, or guests, within a single
Windows Server 2008 server. Hyper-V uses hypervisor architecture. A hypervisor is a lightweight
layer of software that separates hardware and the operating system. It performs simple partitioning
tasks and maintains strong isolation between partitions. Within these partitions, the hypervisor
hosts virtual machines. Microsoft’s implementation is inherently secure, as it contains no
third-party device drivers. This minimizes the attack surface of the host machines.
- UDDI Services Universal Description, Discovery, and Integration (UDDI) services are an
industry specification for publishing and locating information about Web services. In Windows
Server 2008, UDDI capabilities are provided for enterprise networks or between business partners.
With UDDI, developers can publish and interact with Web services directly via their development
tools and business applications.
- Web Server/Internet Information Services 7.0 Internet Information Services 7.0
(IIS 7) is the latest version of a Web services platform from Microsoft. More than an ordinary
Web server, the IIS 7 platform unifies a number of Web-based technologies including Windows
Communication Foundation Web services and Windows SharePoint Services. With IIS 7,
Microsoft has completely changed the way the product works, including new configuration, delegated administration, security enhancements, and real-time diagnostic and troubleshooting
features.
