Windows 2008 Overview

  1. 1. Overview<br />Amit Gatenyo<br />Infrastructure & Security Manager<br />Dario IT Solutions ltd<br />054-2492499<br /><br />
  2. 2. Technology Investments<br />Virtualization<br />Security<br />Web<br />Windows Server Virtualization – WS2008 contains everything needed to support machine virtualization. Hyper-V™ enables IT organizations to reduce costs, improve server utilization, and create a more dynamic IT infrastructure.<br />Presentation Virtualization - Terminal Services accelerates and extends application deployments to any device, improving remote worker efficiency, while helping keep critical intellectual property secure and radically simplifying regulatory compliance<br />Network Access Protection - helps prevent unhealthy devices from accessing corporate resources, NAPenables policy validation, network restriction, remediation and ongoing compliance to ensure network health is not compromised.<br />Read-Only Domain Controller (RODC) - helps reduce corruption and compromise of the system.RODC improves security of branch office servers and reduces risk of stolen information from branch DCs.<br />Active Directory Rights Management Services - helps prevent unauthorized access and use of documents, data, and e-mail. RMS enables document owners to identify authorized users and manage restrictions on usage of documents. <br />Internet Information Services 7.0 – Powerful Web Application and Services Platform<br />Manage with Ease - More efficient administration tools including delegated administration and shared configuration<br />Powerful Hosting of Applications and Services - Expanded application hosting for .NET, ASP, PHP Web applications and XML services.  Web server extensibility throughout<br />Lower Infrastructure Costs - Improved scalability and enhanced security and reliability with automatic application sandboxing<br />Solid Foundation for Your Business Workloads<br />Reliability<br />Management<br />Server Core Installation Option - Minimal installation option for increased reliability, security, and management <br />Next Generation Networking - New TCP/IP stack improves scalability, performance and security. <br />Failover Clustering – Improved setup, validation, management, and geo-clustering deployment simplifies implementation of highly-available failover clusters and helps ensure business continuity.<br />Dynamic Partitioning - Datacenter and Itanium. Delivers mainframe-class reliability. Increases workload resources, and allows one to hot- add and replace processors and memory without rebooting,<br />Server Manager – “One-stop shop” to guide you through installation, configuration, management, and reporting of server roles and features.<br />Windows PowerShell™ - Achieve greater control and productivity using a powerful new command shell and scripting language for accelerated system administration and task automation<br />Power Management – Reduce energy consumption and maintain server performance through processor power management features.<br />High Performance Computing – Increase scalability and performance of HPC workloads and improve management of clustered file systems.<br />

  8. 8. Key New Networking Features<br />Solid Foundation<br />Windows Filtering Platform<br />Receive Window Autotuning<br />Provides filtering capability at all layers of the TCP/IP protocol stack <br />Integrates and provides support for next-generation firewall features<br />Automatically senses network environment and adjusts important performance settings<br />Allows increase of the size of the TCP/IP send / receive window<br />Policy-based Quality of Service<br />Receive-Side Scaling<br />Previous Windows operating systems limits receive protocol processing to single CPU<br />RSS resolves this issue by allowing network load from a network adapter to be balanced across multiple CPUs<br />Prioritize or manage the sending rate for outgoing network traffic<br />Both DSCP marking and throttling can be used together to manage traffic effectively<br />
