thin client computing
Thin Client Computing

What is the most compelling business value case for thin client computing?

personal computers
Personal Computers
  • Demise of the Desktop?
    • Laptop to Desktop ratio in corporations
      • 1 in 5 in 1999
      • 1 in 3 in 2005
      • 1 in 2 in next few years
  • Why?
    • Mobility!
      • Outside and inside of workplace
    • Changes in work habits
      • Used on the road, in the home, into meetings
      • Facilitate collaboration as well as email access
    • Wireless connectivity improvements
    • Battery life improvements
    • Price/Performance gap between laptops and desktops has narrowed considerably
    • Availability of workstation-class laptops for computing intensive tasks like software development and computer-aided design
    • Laptop reliability has improved
  • Laptop concerns
    • Security!
pc virtualization
PC Virtualization
  • PC hardware moved into data center as part of PC blades
    • Fit into a chassis that can be centrally managed
    • Several users can share a single blade
    • Simplifies PC management
  • Thin client on desktop that functions as an extended keyboard, monitor, and mouse
servers
Servers
  • Midrange computers in data center that provide applications, web services, and storage to client devices
  • Defining features
    • Use faster, multi-core processors than pc’s
      • 64 bit processors
    • Often run Unix or Linux as their operating systems
    • Often deployed in server farms or blades for easy management and flexibility
    • Less costly than mainframes
    • Ability to load balance
mainframes
Mainframes
  • Large, very fast computers that support the enterprise
    • Many legacy systems run on mainframes
    • Known for reliability and scalability
    • Can replace many midrange servers and can cut IT staff costs as a result
aarp mainframe example
AARP Mainframe Example
  • Members
    • 35 million members
    • 76 million baby-boomers preparing for retirement
  • Central customer database
    • Can be accessed by
      • Members
      • Trading partners
        • Insurance providers
        • Retirement communities
  • Technology
    • Mainframe used for customer database
      • Centralized
        • Member information can be maintained and secured independently of the numerous IT applications that use it
      • Reliable
      • Scalable
        • Will support increasing numbers of transactions as membership grows
      • Continuously updated
        • Makes it easier to market products and services to its members
      • Application-independent
        • Common interface to the database for suppliers
        • Standard method for integrating applications with the database
what a supercomputer looks like
What a SuperComputer Looks Like

Terabyte: A thousand billion bytes or a thousand gigabytes

Gigaflop: One billion floating point operations per second

corporate supercomputing
Corporate Supercomputing
  • Ping Inc., golf club maker
    • Uses supercomputer to run simulations of golf club designs
    • Has drastically reduced development time
  • Goodyear Tire & Rubber Co.
    • Uses supercomputing for tire simulations
    • Reduces amount of money spent on building physical tire prototypes, from 40% to 15% of the research and development budget
  • Supercomputing also supports
    • Digital animation
    • Bioinformatics
    • RFID chips and the huge databases they create
overview of software
Overview of Software
  • Computer programs: sequences of instructions
  • Two Types
    • Systems software:coordinates the activities of hardware and programs
    • Application software: helps users solve particular problems
supporting individual group and organizational goals
Supporting Individual, Group, and Organizational Goals
  • Sphere of influence: the scope of problems and opportunities addressed by a particular software application
    • Personal
    • Workgroup
    • Enterprise
software operating system
Software: Operating System
  • When selecting an operating system, you must consider the current and future requirements for application software to meet the needs of the organization. In addition, your choice of a particular operating system must be consistent with your choice of hardware.
systems software operating systems
Systems Software: Operating Systems
  • Operating system (OS): set ofprograms that control the hardware and act as an interface with applications
  • Common hardware functions
    • Get input (e.g., keyboard)
    • Retrieve data from disks and store data on disks
    • Display information on a monitor or printer
operating systems19
Operating Systems
  • User interface
    • Allows individuals to access and command the computer system
    • Command-based user interface: uses text commands
    • Graphical user interface (GUI): uses icons and menus to send commands to the computer system
    • Bringing Vista to life
operating systems20
Operating Systems
  • Hardware independence
    • Application program interface (API): allows applications to make use of the operating system
  • Memory management
    • Control how memory is accessed and maximize available memory and storage
slide21

Operating Systems

  • Processing tasks
    • Multitasking: more than one program running at the same time
    • Time-sharing: more than one person using a computer system at the same time
    • Scalability: ability to handle an increasing number of concurrent users smoothly
  • Networking capability: features that aid users in connecting to a computer network
operating systems22
Operating Systems
  • Access to system resources
