7 One Solution Thin-Client/ Server Computing 7

8 What Is Thin Client / Server Computing? TCSC is about using your existing IT infrastructure and deploying applications to all the users that need them. TCSC achieves this through 100% Server-based execution The ability to turn any device thin or fat into an ultra-thin thin client 8

9 TCSC Key Parts Three Components Apps Install & Run on Server Applications Accessed From Client Only screens, mouse clicks & keystrokes travel the network 9

10 TCSC Technologies Description Client, Network and Server Separates application s s logic from user interface Transports to client over standard protocols Makes any client fat or thin a thin client Highly efficient 1/10th normal bandwidth Keystrokes, mouse clicks, screen updates Shared Ethernet 10 Mbps Wireless Ethernet 2 Mbps ISDN 64 Kbps Modem 28.8 bps ICA Stream 10

11 TCSC Technologies Description Server Multi-user user component of Windows NT Server TM Allows multiple, concurrent users 20+ per processor 11

12 TCSC Major Benefit Thin Client / Server Computing meets application deployment challenges while helping to lower the total cost of application ownership. 12

13 TCSC Solves the IT Challenges M anagement Single-Point Control A ccess Universal Application Access P erformance Bandwidth-Independent Performance S ecurity Eyes-Only Security 13

14 Feature Highlights M anagement Single-Point Control Keeps I/S in Command Deploy, manage and support in minutes, not months from one location Make installations, updates, additions once, on the WinFrame Server Robust set of built-in in administrative utilities Integrate database, file and Web servers Support up to 20 users per processor Scalable on demand to thousands 14

15 M anagement Tools Session shadowing System performance monitoring Port configuration and administration Console, dial-up or LAN administration SMP server support Dynamic load balancing Multiserver administration tools Reciprocating jigsaw 15

16 Feature Highlights A ccess Universal Application Access Virtually Any Application from Any Client Pentium PCs, Windows terminals, DOS PCs, Macs, UNIX workstations, OS/2 desktops, network computers Business-critical applications even on the Internet/Intranet. No rewrites. Run anywhere True local/remote application transparency 16

17 A ccess Client/Server Integration One-click dial-in in easy connect to server Client drive mapping local drive access from server Cut and paste between local and remote application sessions Automatic reconnection/session resume Background file transfer 17

18 Feature Highlights P erformance Bandwidth-Independent Performance For Everyone, Everywhere ICA keeps network-intense application activity on the corporate backbone Blazing speed on LANs Efficient use of WANs saves money LAN-like performance over WAN and dial-up Analog or ISDN modems WANs Wireless LANs Internet 18

19 P erformance LAN, WAN, Dial-Up ICA protocol optimized for low-bandwidth connections 10 Kbps Persistent object caching reduces retransmissions Specialized bad app detection prevents CPU lockup Memory management tuned for concurrent Windows users 19

20 Feature Highlights S ecurity Eyes-Only Security For Vital Applications and Data Data and applications stay on the network never downloaded to client Users worldwide can access the same centralized information Administrators can eliminate security issues concerning dispersed databases Fully incorporates Windows NT security 20

21 S ecurity Windows NT authentication Internal user list (name/password) Data encryption Required or roaming callback Logon attempt limits Connection duration limits Inactivity timeout Time-of of-day access restrictions Master application execution User groups 21

22 S ecurity Server/drive access restrictions by drive, directory, file, user, day and time Integrates with NetWare Bindery, NDS and Windows NT Domain services Supports third-party authentication/ encryption solutions 22

23 Perceived Disadvantages of Thin Client Computing High network infrastructure requirements Reliance of network for productivity Powerful servers / High capital costs 23

24 Software Vendors 24

25 Microsoft 25

26 Microsoft Products Windows NT Server - Terminal Server Edition (TSE) TSE Windows based client Windows CE - for Windows Based Terminals Microsoft Cluster Server (MSCS) 26

27 What is Microsoft Terminal Server (TSE)? TSE - Server Version of Microsoft Windows NT Server 4.0 that adds UNIX-like multiuser capabilities and support for thin-client Windows-based terminals All applications run 100% on the server Incorporates Citrix WinFrame and Prologue technologies Three components multiuser server core, TS client SW, and RDP protocol (T.120 based) 27

28 TSE Client Super-thin client Presents Win32 GUI (Windows 95 GUI) Runs RDP protocol to talk to Server Downloads screen from Server Uploads keystrokes and mouse clicks to Server 28

29 TSE Compatibility/Interoperability Application Compatibility Runs 16- and 32-bit Windows apps Supports MS-DOS and OS/2 character- based applications Standard Intel Servers Including SMP (Uses NT 4 HCL) Compatible with all NT Applications* *There are probably some exceptions 29

30 Windows CE Windows CE Devices Lightest MS Operating System CE can connect to TCSC servers Many devices now run CE 30

31 Microsoft Cluster Server Load balancing / clustering TSE 4.0 does not come with any load balancing capabilities 2 MSTS boxes can be clustered in a failover role only (no load balancing) with MSCS 1.0 TSE 2000 (due out in CY99) will offer load balancing and clustering based on MSCS 2.0 Citrix s s MetaFrame adds load balancing and clustering to MSTS

32 Citrix Systems 32

33 Citrix Products MetaFrame WinFrame SecureICA DirectICA Installation Management Services Resource Management Services Load Balancing Services 33

34 MetaFrame MetaFrame, on the server side: Adds user, system, and application management Load balancing capabilities for Terminal Server farms MetaFrame, on the client side: MetaFrame allows a broader range of client types (UNIX, Mac, DOS, X, JAVA, ActiveX browser based, and Wintel) Enhanced protocol (ICA), support for sound, lower bandwidth requirements, IPX and NetBEUI support, local printing Preserves existing WF (1.6 or newer) environments 34

35 WinFrame WinFrame, on the server side Like MetaFrame, although based on Windows NT

36 Secure ICA Secure ICA Allows encrypted Thin Client ICA sessions 36

37 Direct ICA Direct ICA Allows client devices to be connected to the server via serial ports rather than a LAN Designed for legacy infrastructure environments 37

38 Installation Management Services Installation Management Services Allows applications to be managed across multiple servers Two components Packager Installer 38

39 Resource Management Services Resource Management Services Performance and usage monitoring tool for NT 39

40 Load Balancing Services Load Balancing Services Creates server farms across which users can be distributed 40

41 Client Devices 41

42 Client Devices Windows Based Terminals Network Computers Standard PCs 42

43 Windows Based Terminals (WBTs) What are Windows Based Terminals? Very low cost hardware device < $1000 per desktop, 2-4 MB ROM, MB RAM, SVGA Available from traditional PC vendors as well as terminal vendors Based on a ROM-embedded Windows OS Very low maintenance costs, bad units can be swapped out, no moving parts Users see familiar Win32 GUI Replacement for green-screen terminals Perfect for users who use up to four screens daily ( , Web, WP, LOB) 43

44 Windows Based Terminals (WBTs) All WBTs have a few things in common They cost less than PCs They cost less to support than PCs They are stateless They are designed to save administrative costs 44

45 Windows Based Terminals (WBTs) WBTs work well when Users work with a limited number of programs Many users share one workstation Remote users access centralized data Replacements for green-screen terminals 45

46 Windows Based Terminals (WBTs) WBTs do NOT work well when Users need significant local processing power Users need to install local apps User need many different peripherals 46

47 Network Computers (NCs) What are Network Computers? Devices that run a JAVA based operating system Applications must be rewritten for JAVA Smaller servers can be used 47

48 Standard PCs Net PCs Standard Desktops Redeployed Computers 48

49 Net PCs Low cost hardware device <$500 per desktop, runs Windows, MB RAM, HD Available from traditional PC vendors 49

50 Standard Desktops High capital cost $2000-$4000, $4000, MB RAM, SVGA, Hard Drive Highest TCO Can still be administered with MSZAK Highest maintenance 50

51 Redeployed Computers Existing HW can be used (redeployment of 386 and 486 based units) No up-front capital expenditures Environment friendly :) 51

52 Future of TCSC Balance Outsourcing Remote Users 52
