Transcript

  • 1. WELCOME ADDRESS Prof. Navneet Goyal Department of Computer Science & Information Systems BITS, Pilani
  • 2. Topics
    • Cloud Computing
    • High Performance Computing
    • Software Modeling
  • 3. Cloud Computing
    • Web-email (remember hotmail!!)
    • Web folders
    • Bank ATMs
    • Switching mobile phones
    • Device independence
    • 3.5 bn mobile phones worldwide (1/3 rd in China & India)
    • Open source stacks
    • Privacy, security, & ownership
  • 4. Cloud Computing
    • Have you ever wondered why searching for files on your own PC takes much longer than searching the web using a search engine?
  • 5. Cloud Computing
    • Three main purposes
    • Software as a service (SaaS)
      • Employees in different locations collaborating using voice, video etc.
      • Enterprise resource management through internet
    • Platform as a service (PaaS)
      • Developing software on a shared platform on the cloud
    • Infrastructure as a service (IaaS)
      • Getting service from a full computer infrastructure through the internet
      • Storage & databases
  • 6. Cloud Computing
    • Collection of servers owned by a cloud provider
    • Cloud automatically utilizes the right no. of servers, adding or releasing servers, as load fluctuates
    • Data Centers
  • 7. Cloud Computing
    • “ New” computing model
    • Computing chores increasingly move off individual desktops and out of corporate computer centers to be handled as services over the Internet
    • Applications
      • Search
      • Social networking
      • Web email
      • Web albums
      • Web hosting
  • 8. Cloud Computing
    • Driving forces behind cloud-based computing include:
      • plummeting cost of storage
      • ubiquitous broadband
    • Computing as a utility
    • IBM and DEC conceived computing as a utility in early 1990s which is becoming a reality now
  • 9. Cloud Computing
    • PCs – hardware centric
    • Client-server Model – software centric
    • Cloud computing – service centric
  • 10. Cloud Computing: Possibilities
    • Organizations can scale to massive capacities without having to invest in
      • New infrastructure
      • Train people
      • Acquiring new software
    • Data intensive scientific research
      • Genome Project
  • 11. Cloud Computing: Concerns
    • Larry Ellison, CEO & founder ORACLE
    • Cloud Computing is "fashion-driven" and "complete gibberish“
    • Richard Stallman, Founder GNU
    • “ One should not use web applications to do your computing if you do not want to lose control,“
    • “ Do your own computing on your own computer”
    • Interoperability between cloud computing vendors
    • Safeguard against outages (SLA)
    • Total dependence on the Internet (QoS)
    • Real-time applications
  • 12. Cloud Computing
    • What Academia & research community gains from Cloud Computing?
  • 13. High-Performance Computing
    • Computer Systems approaching the teraflops/petaflops region are considered as HPC computers
    • Mainly linked to computing used for scientific research
    • HPTC – CFD, EDA, CAE
    • BI applications
    • Benchmarking
  • 14. High-Performance Computing
    • Multi-core architectures
    • Application specific hardware
  • 15. Software Modeling
    • How best to develop software?
    • Modeling Languages (UML), frameworks (MDA), & Processes (EUP)
    • Bound by PLs
    • IDEs - direct an organization toward specific tools as well as techniques of modeling
  • 16.
