1 Clstering and Clstering Tools Testing Migrate configration settings Qick configration and trobleshooting Storage configration Performance and reliability Secrity 20

2 Enhanced Web Services Microsoft Internet Information Services (IIS) Enhanced secrity Easier application of patches Easier for programmers to write and configre Web applications Better management tools: IIS Manager 21

3 Windows Server Core Minimm server configration Advantages: No GUI overhead Less disk space and memory needed Smaller attack srface Interact with server via command line 22

4 Windows PowerShell Command-line interface that offers a shell Perform common administration tasks Use cmdlets 130 command line-tools Scripting langage 23

5 Windows PowerShell (cont d.) Figre 1-3 Using Windows PowerShell for a directory listing Cortesy Corse Technology/Cengage Learning 24

6 Virtalization Using Hyper-V Capabilities: Compatible with clstering Able to handle p to a for-processor SMP compter Can be sed with Windows and Linx operating systems Compatible with different types of disk storage methods Enables fast migration from one compter to another Can hose 64-bit and 32-bit operating 25

7 Reliability Kernel rns in privileged mode Core programs; compter code of operating system Extra level of secrity Protected processes Compter program or portion of program Protects prematre interrption Management featres: Server Manager Wizards Windows Reliability and Performance Monitor 26

8 Reliability (cont d.) Activity 1-2: Viewing Rnning Processes Objective: View the processes rnning in Windows Server

9 Mltitasking and Mltithreading Mltitasking Ability to rn two or more programs at the same time Mltithreading Capability of programs written to rn several program code blocks at the same time Preemptive mltitasking 28

10 Mltitasking and Mltithreading (cont d.) Figre 1-4 Using Task Manager to view rnning processes Cortesy Corse Technology/Cengage Learning 29

11 Planning a Windows Server 2008 Networking Model Network Commnication system Enables compter sers to share eqipment, software, data, and transmissions Peer-to-peer networking Spreads resorce administration among server and non-server members of network Used by small bsinesses Server-based networking Centralizes network administration on servers Used by medim and large networks 30

12 Planning a Windows Server 2008 Networking Model (cont d.) Figre 1-5 Networking across continents Cortesy Corse Technology/Cengage Learning 31

13 Peer-to-Peer Networking One of the simplest ways to configre a network No special compter needed Disadvantages: Network management decentralized Secrity is responsibility of each ser Less effective as nmber of workstations exceeds 10 Activity 1-3: Determining if a Compter Is in a Domain or a Workgrop Objective: Discover if a particlar compter is in a domain or a workgrop 32

14 Server-Based Networking Server Single server can act as file and print server, Web server, network administration server, database server, server Can handle many sers at once Advantages Single log on Stronger secrity Sharing of files and resorces server 33

15 Server-Based Networking (cont d.) Advantages (cont d.) Software applications are shared Databases are managed and secred Easier backps Resorce sharing can be cstomized Software pdates qicker and easier to install 34

16 Server-Based Networking (cont d.) Figre 1-7 A server-based network Cortesy Corse Technology/Cengage Learning 35

17 Protocols for the Windows Server 2008 Networking Model Protocol sets gidelines for: Data formatting into packets and frames Data transmission Interpretation of packets and frames Packets and frames Units of data transmitted from a sending compter to a receiving compter 36

18 Protocols for the Windows Server 2008 Networking Model (cont d.) Transmission Control Protocol/Internet Protocol (TCP/IP) Site of protocols and tilities that spport commnication across LANs and the Internet Local area network (LAN) Network of compters in relatively close proximity TCP/IP sed for several reasons 37

19 Transmission Control Protocol Provides for reliable end-to-end delivery of data by controlling data flow Connection-oriented commnication Ensres that packets are delivered in correct seqence with accrate contents 38
