Evolution of Computing

• Mainframe
• Mini
• Computer Networks
• PC LAN WAN Client Server Computing
• Internet Computing
• Web Services Services Oriented Architecture
• Utility Computing, Grid, Ubiquitous Computing

4
Key Ideas from Networking

• Ethernet from DIX
• TCP/IP Internet
• Network is the Computer Sun
• Earth Centric World to Sun Centric World
  Connecting Computers to form a Network to Attach
  a Computer to Network
• Synchronous AND Asynchronous Communications

5
First Generation Network Computer

• Dumb Terminals
• Smart Terminals
• NC Device
• Thin Clients
• Diskless PCs

6
Internet Age Network Computing

• HTML for Data XML for Programs
• Web Services
• Middle Layer has Evolved
• Devices have multiplied (Computer is NOT the
  only device to capture / distribute information)

7
Critical Success Factors

• Cost Acquisition, Upkeep, Up-gradation
• Security Data Loss, Virus, Content, Application
  Control
• Manageability Software Distribution,
  Environment, Interface, Over-personalization,
  Measurability, Monetization

8
Offerings

• Yesterday
• Oracle NC
• NCD, VXL Instruments Terminals (Thin Clients)
• Today
• Sun Utility Offer
• IBM On Demand Computing
• HP Utility Data Center

9
Success Stories

• LIC in India
• Many Banks in Europe
• Auto Companies
• Airlines / Travel Agents (for years!)

10
Lessons Learnt

• Right Technology at right time (todays networks
  have bandwidth)
• Hardware alone is NOT the issue (applications
  have to re-engineered from client server to
  middleware-based architecture)
• Management needs clarity in thinking to push NC
  into prganizations

Summary

• Network Computing is here to say
• Pragmatism needed to embrace network computing
• Cost is important but manageability is the issue
• Thanks for your Patience
