Introduction l.jpg

  • “Cloud computing is a computing paradigm shift where computing is moved away from personal computers or an individual application server to a “cloud” of computers. Users of the cloud only need to be concerned with the computing service being asked for, as the underlying details of how it is achieved are hidden. This method of distributed computing is done through pooling all computer resources together and being managed by software rather than a human.“

Cloud Computing

  • Cloud computing is a novel platform for computing and storage.

  • Cloud computing provisions and configures servers as needed.

  • It allows for more efficient use of the enterprise resources and applications.

  • It introduces accountability and streamlines computing needs of an enterprise.

B. Ramamurthy

Possibilities l.jpg

  • It is possible to consolidate all the needs of an organization in a systematic and accountable fashion.

  • It is possible to procure computing related resources similar to how you rent a place for living.

  • For example,

    • you can buy storage on demand from in a service it offers called the “S3”

    • You can buy computation service from in its “elastic cloud computing” service (EC2)

  • Usage example: You are in charge of IT in a local company. You have an immediate need for backing up entire set up for a short period of time as a mock up for disaster recovery. What would you do?

  • Amazon, Google, IBM, yahoo!, and many prominent companies are involved in it.

  • NSF, Computing Research Association (CRA), CCC (Computing Community Consortium) all support it.

What can it do for you l.jpg
What can it do for you?

  • Can quickly launch most applications (ex: Web 2.0 applications)

  • It makes it possible to scale up applications (tera, peta, and exa bytes of storage as well as MFlops of CPU power)

  • It can provide security, isolation and other non-functional capabilities also.

Usage scenario l.jpg
Usage Scenario

  • Internal innovation

  • Virtual worlds (massively multiplayer online games MMPOG)

  • E-business

  • Personal hobbies

Features l.jpg
Features document)

  • Provisioning manager (IBM’s Tivoli) allocates and deallocates resources, reserves resources for suture use; runs on (WebSphere) application server

  • Provisioning monitor (IBM’s Tivoli) monitors the health of the allocated resources

  • XEN hypervisor is used for creating virtual machines

Advantage l.jpg
Advantage document)

  • Typically a pilot team needs about twelve weeks to identify, procure and build a pilot infrastructure and additional time to build a security compliant software stack so that developers can begin building or deploying applications and code.

  • The cloud provides a framework and offering that reduces the process to approximately 1 hour.
