Modern Operating System Windows Server 2008
- 2. INTRODUCTION Windows Server 2008 is built from the same code base as Windows Vista; therefore, it shares much of the same architecture and functionality.
- 3. • Since the code base is common, it automatically comes with most of the technical, security, management and administrative features new to Windows Vista • Improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features.
- 4. • Improved Windows Firewall with secure default configuration; .NET Framework 3.0 technologies, specifically Windows Communication Foundation, Microsoft Message Queuing and Windows Workflow Foundation. • The core kernel, memory and file system improvements
- 5. • Processors and memory devices are modelled as Plug and Play devices, to allow hot-plugging of these devices. • This allows the system resources to be partitioned dynamically using Dynamic Hardware Partitioning; each partition has its own memory, processor and I/O host bridge devices independent of other partitions.
- 6. Default user interface for Server Core- • Windows Server 2008 includes a variation of installation called Server Core. Server Core is a significantly scaled-back installation where no Windows Explorer shell is installed.
- 7. • All configuration and maintenance is done entirely through command line interface windows, or by connecting to the machine remotely using Microsoft Management • Console. However, Notepad and some control panel applets, such as Regional Settings, are available.
- 8. Active Directory roles- • Active Directory roles are expanded with identity, certificate, and rights management services. • Active Directory allows network administrators to centrally manage connected computers, to set new applications to multiple computers.
- 9. Failover Clustering- • Windows Server 2008 offers high- availability to services and applications through Failover Clustering. Most server features and roles can be kept running with little to no downtime. • This cluster validation process tests the underlying hardware and software directly.
- 10. Hyper V- • Hyper-V is hypervisor-based virtualization software, forming a core part of Microsoft's virtualization strategy. It virtualizes servers on an operating system's kernel layer.
- 11. Windows System Resource Manager- • Windows System Resource Manager (WSRM) is integrated into Windows Server 2008. It provides resource management and can be used to control the amount of resources a process or a user can use based on business priorities.
- 12. Server Manager- • Server Manager is an improvement of the Configure my server dialog that launches by default on Windows Server 2008 machines. However, rather than serve only as a starting point to configuring new roles, Server Manager gathers together all of the operations users would want to conduct on the server, such as, getting a remote deployment.
- 13. Core OS improvements- • Fully multi-componentized operating system. • Improved hot patching, a feature that allows non-kernel patches to occur without the need for a reboot.
- 14. Active Directory improvements- • Read-only domain controllers (RODCs) in Active Directory, intended for use in branch office or other scenarios where a domain controller may reside in a low physical security environment.
- 15. Policy related improvements- • All of the Group Policy improvements from Windows Vista are included. • Group Policy Management Console (GPMC) is built-in. The Group Policy objects are indexed for search and can be commented on.
- 16. Improvements • Disk management and file storage improvements. • Protocol and cryptography improvements. • Improvements due to client-side (Windows Vista) enhancements.
- 17. Removed Features- • The Open Shortest Path First (OSPF) routing protocol component in Routing and Remote Access Service, has been removed. • Services for Macintosh, which provided file and print sharing via the now deprecated AppleTalk protocol, has been removed.
- 18. Editions- • Windows Server 2008 Standard. Windows Server 2008 Enterprise • Windows Server 2008 Datacentre • Windows HPC Server 2008 • Windows Web Server 2008 • Windows Storage Server 2008
