MCSA Guide to Installing and Configuring Windows Server 2012/R2, Exam 70-410 Chapter 1 Introducing Windows Server 2012/R2 Public  The Role of a Server Operating System The functions a server performs depend on: – Type of business using the server – Size of the business – Extent to which the business has committed to using technology to aid operations A server is used to provide services that aid the operations of an organization Public 2 © Cengage Learning 2015  Server: Hardware or Software? A computer becomes a server when software is installed on it that provides a network service to client computers. Operating Systems such as Windows 10/11 and its predecessors are designed to be on desktop computers – These OSs can perform server functions such as file and printer sharing Server operating systems: OSs designed to emphasize network access performance and run background processes rather than desktop applications Public 3 © Cengage Learning 2015  Server Operating Systems Versus Desktop Operating Systems Windows Server 2012/R2 network services: – File and Printer sharing – Web server – Routing and Remote Access Services (RRAS) – Domain Name System (DNS) – Dynamic Host Configuration Protocol (DHCP) – File Transfer Protocol (FTP) Server – Active Directory – Distributed File System (DFS) – Hyper-V Public 4 © Cengage Learning 2015  Server Operating Systems Versus Desktop Operating Systems Windows 10 desktop OS supports only Hyper-V, File and Printer Sharing, Web Server, and FTP Server in limited capacity. Windows 10 is restricted to 20 logged-on network users Windows Server 2012/R2 supports fault-tolerance features such as: – Redundant array of independent disks (RAID) 5 volumes – Load balancing Public 5 © Cengage Learning 2015  Windows Server 2012/R2 Editions Windows Server 2012/R2 editions have been streamlined compared with Windows Server 2008: – Datacenter – Standard – Essential – Foundation Businesses can choose the best solution for their size and services required Public 6 © Cengage Learning 2015  Datacenter and Standard Editions Datacenter Edition – you can install an unlimited number of virtual instances of the OS. – Datacenter with Hyper-V can be installed on a physical server Install as many virtual machines as you need – Must purchase one Datacenter Edition license for every two physical processors installed on a server. Standard Edition - has all the features of Datacenter Edition and the same processor licensing conditions – Permits only two virtual instances Public 7 © Cengage Learning 2015  Datacenter and Standard Editions Both Datacenter and Standard editions support: – Up to 4 TB of RAM – Up to 64 physical processors – Server clusters with up to 64 nodes per cluster Both editions have the option to be installed without the standard graphical user interface (GUI). – A mode called Server Core (now the default) Both editions require client access licenses (CALs) – Legally mandated for each user who logs on to the server Public 8 © Cengage Learning 2015  Essential Edition Essential Edition - aimed at small businesses with 25 or fewer users.

Host computer - the physical computer on which VM software is installed and VMs run. Virtualization software - software for creating and managing VMs and creating the virtual environment. Hypervisor - virtualization software component that creates and monitors the virtual hardware environment Public 13 © Cengage Learning 2015  Public Cloud versus Private Cloud Public cloud - cloud computing service provided by a third party – Examples: DropBox, SkyDrive, Google Apps Private cloud - cloud computing service provided by an internal IT department – Typical services include virtual desktops, storage, and applications Virtual desktop infrastructure (VDI) – Users connect to private cloud with a Web browser or client software – Can access their desktop from any Internet connection Public 14 © Cengage Learning 2015
