What is it? What is it? ... Is it- 'Oh, I am goingto access data on a server on the Internet.'
That is cloud computing?
The interesting thing about cloud computing is
that weve redefined cloud computing to
include everything that we already do.

What is Cloud Computing?
Definitions of Cloud Computing
More details are on http://jameskaskade.com/?p=594
Wikipedia n/a Cloud computing is Internet- (cloud-) based development and use of computertechnology (computing). In concept, it is a paradigm shift whereby details areabstracted from the users who no longer need knowledge of, expertise in, or controlover the technology infrastructure in the cloud that supports them. It typicallyinvolves the provision of dynamically scalable and often virtualized resources as aservice over the Internet.
Gartner Thomas Bittman Cloud Computing: a style of computing where scalable and elastic IT-enabledcapabilities are delivered as a service to external customers using Internettechnologies.
AMR Research Bruce Richardson,
and esle
Cloud computing is the next-generation of software as a service, in which a
complete software environment is licensed as a subscription from a software vendorand low-cost, secure, and dependable IT hardware infrastructure is rented from autility-computing provider on demand. (omitted)
THINKstrategies Jeff Kaplan A set of web-based tools and services which permit users to acquire computingresources and development capabilities to build or support applications, or performspecific IT functions on a pay-as-you-go basis.
EnterpriseStrategy Group
Mark Bowker,Steve Duplessie
Cloud computing is nothing more than a service model where business workloadsare deployed, transparently executed internally or somewhere on the Internet, andbusinesses only pay for what they consume. (omitted)
IDC Frank Gens Cloud Computing: an emerging IT development, deployment and deliverymodel, enabling real-time delivery of products, services and solutions over theInternet (i.e., enabling cloud services)
The 451 Group Dan Kusnetzky,Rachel Chalmers,and else
Cloud computing describes a service model that combines a general organizingprinciple for IT delivery, infrastructure components, an architectural approach and aneconomic model basically, a confluence of grid computing, virtualization, utilitycomputing, hosting and software as a service (SaaS).
Forrester/JupiterResearch
James Staten A standardized IT capability (services, software, or infrastructure) delivered viaInternet technologies in a pay-per-use, self-service way.

Squeezing the Definitions
A computing environment to elastically provide virtualized resources as a
service over the Internet in a pay-as-you-go manner
elastically: enable to avoid under-utilization(idle servers) and over-
utilization(blue screen)
virtualized: enable to put whatever end user wants to use into the cloud,and access in anytime, anywhere, any devices
pay-as-you-go: enable a new ecosystem for end user, service provider, and
vendors

Computing Evolution
Mainframe
Nearly all mainframes had the ability to run multiple operating systems, andthereby operate not as a single computer but as a number of virtualmachines
Grid
The wave of Grid occurred in the 1990s with a way to solve big problems suchas protein folding, financial modeling, earthquake simulation, and climate/weather
modeling. The main use of Grid is applying the resources of manycomputers in a network to a single problem at the same time.

Computing Evolution (contd)
Cluster
Clusters are loosely coupled commodity servers usually deployed toimprove performance and/or availabilityover that of a single computer (e.g.mainframe, MPP, or SMP server), and also significantly more cost-effective
than single computers of comparable speed or availability
VirtualizationA virtual machine (VM) is a software implementation of a physical machine. The
virtual machines allow the sharing of the underlying physical machineresources between different virtual machines, each running its own
operating system

Prospects for Cloud Computing
Large enterprises are building their own private clouds
Large enterprises will become part-time cloud-computing vendors Small-sized to medium-sized businesses as well as large enterprises will be run on the
cloud
Coding & development skills will take a back seat to project management, quality
assurance testing, business analysis, and other high-level abstraction thinking
IT departments will shrink as users go directly to the cloud for IT resources
Cloud computing providers will support information security as if banks secure money
The browser will be all the desktop software you need
Game services will be one of the most interesting applications of Cloud Computing
Cloud Optimization and Grid Delivery will be an interesting business part to reducetotal cost

estimates cost savings on service and storage to be close to $1 million
37Signals(http://37signals.com/)

New York Times(http://www.nytimes.com) use EC2 to process terabytes of archival data using hundreds of EC2 instances within 36

Animoto(http://animoto.com/) an online presentation video generator that needs gobs of computing power for video
processing
recently successfully withstood a surge in Web traffic that would kill most companiessystems by scaling up their processing power quickly using EC2 with RightScale
Animoto ramped from 25,000 users to 250,000 users in three days, signing up
20,000 new users per hour at peak
Using RightScale, EC2 instances automatically scaled out 40 to 4000 at that time
