Evolution of Computing . . .

• Network Computing– Network is computer (client - server)– Separation of Functionalities

• Cluster Computing– Tightly coupled computing resources:

CPU, storage, data, etc. Usually connected within a LAN

– Managed as a single resource– Commodity, Open source

• Grid Computing– Resource sharing across several domains– Decentralized, open standards– Global resource sharing

• Utility Computing– Don’t buy computers, lease computing power– Upload, run, download– Ownership model

Evolution of Computing (contd. . .)

Evolution of Computing (contd. . .)

• Service and data are in the cloud, accessible with any device connected to the cloud with a browser.

• A key technical issue for developer:– Scalability

The Next Step: Cloud Computing

GRID

• Flexible , but Complex

CLUSTER

• Cost-effective , but Confined

• Personal Computer– One to One

• Client/Server– One to Many

• Cloud Computing– Many to Many

A style of computing where massively scalable IT-enabled capabilities are provided "as a service" over the network .

•“I only care about results, not how IT capabilities are implemented”

Acquisition Model

Service based

•"I want to pay for what I use, like a utility"

Business Model

Usage based

•"I can access services from anywhere, from any device"

Access ModelInternet, Intranet

Technical ModelDynamic, flexible

“I can scale up or down capacity, as needed"

What’s Cloud Computing ?

Characteristics of Cloud Computing

• Virtual – Physical location and underlying infrastructure details are transparent to users

• Scalable – Able to break complex workloads into pieces to be served across an incrementally expandable infrastructure

• Efficient – Services Oriented Architecture for dynamic provisioning of shared compute resources

• Flexible – Can serve a variety of workload types – both consumer and commercial
