Rather than having seven Terminal Services clients queued up to log on and run thin client sessions, on an eight-core processor server, each of the seven client sessions can simultaneously log on and run applications at processor speed. Again, this is a technology that a network administrator does not install, configure, or run separately, but is now built in to Windows , which ultimately improves the raw performance of applications and tasks that used to queue up serially on a server that can now be handled in parallel with each core processor handling the added tasks.

This service helps to ensure user sessions are completely terminated when a user logs off of a system. It removes temporary file content, cache memory content, and other information typically generated during a user session, but deemed unnecessary for longer-term storage. This service is particularly useful for organizations using Windows Terminal Services where user sessions are routinely created on a server, and for security purposes, the user profile data is removed when the user logs off of the session.

Hyper-V is a technology built in to the core of the operating system in Windows that greatly enhances the performance and capabilities of server virtualization in a Windows environment. In the past, virtual server software sat on top of the network operating system and each guest session was dependent on many shared components of the operating system. Hyper-V provides a very thin layer between the hardware abstract layer of the system and the operating system that provides guest sessions in a virtualized environment to communicate directly with the hardware layer of the system.

Without having the host operating system in the way, guest sessions can perform significantly faster than in the past, and guest sessions can operate independent of the host operating system in terms of better reliability from eliminating host operating system bottlenecks.

Hyper-V and server virtualization is covered in more detail in Chapter 37, "Deploying and Using Windows Virtualization. As much as there have been significant improvements in Windows under the hood that greatly enhance the performance, reliability, and scalability of Windows in the enterprise, Windows servers have always been exceptional application servers hosting critical business applications for organizations.

Windows continues the tradition of the operating system being an application server with common server roles being included in the operating system. When installing Windows , the Server Manager console provides a list of server roles that can be added to a system, as shown in Figure 1. This book focuses on the Windows operating system and the planning, migration, security, administration, and support of the operating system.

Windows is also the base network operating system on top of which all future Windows Server applications will be built.

The first item of note for users familiar with the first version of Windows Server is that the R2 edition is only available for bit systems.

Whilst some editions of the original Windows Server operating system were available in bit versions, this is now no longer the case for the R2 version. The Foundation edition of Windows Server R2 is the new entry level edition and is designed specifically with the small business in mind. It is the least expensive of the various editions and lacks some of the more advanced functionality typically found in the higher end editions such as full Active Directory support and Hyper-V virtualization capabilities.

In addition, the Foundation edition limits some of the included features, such as restricting the number of concurrent remote desktop services connections to 50 and is able to access a maximum of 1 processor and 8GB of RAM. As previously stated, whilst the original version of Windows Server supported both bit and bit versions, the R2 version supports only bit processors. Download Microsoft Edge More info.
