China & India) Open source stacks Privacy, security, & ownership

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?

Cloud ComputingThree 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 internetStorage & databases

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

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

Cloud Computing Driving forces behind cloud-based

computing include: plummeting cost of storageubiquitous broadband

Computing as a utility IBM and DEC conceived computing as a

utility in early 1990s which is becoming a reality now

Cloud Computing PCs – hardware centric Client-server Model – software centric Cloud computing – service centric

Cloud Computing: Possibilities Organizations can scale to massive

capacities without having to invest inNew infrastructureTrain peopleAcquiring new software

Data intensive scientific research Genome Project

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

Cloud Computing What Academia & research community

gains from Cloud Computing?

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

High-Performance Computing Multi-core architectures Application specific hardware

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
