7. Cloud Wars
Merrill Lynch recently issues a research note
• ‚The Cloud Wars: $100+ billion at stake‛ (07 May 2008).
• The analysts write that by 2011 the volume of cloud computing market opportunity would amount
to $160bn, including $95bn in business and productivity apps (email, office, CRM, etc.) and $65bn
in online advertising.

8. Introduction to Cloud Computing

9. What is Cloud Computing?
Definitions of Cloud Computing
Wikipedia n/a Cloud computing is Internet- (‛cloud-‛) based development and use of computer
technology (‛computing‛). In concept, it is a paradigm shift whereby details are
abstracted from the users who no longer need knowledge of, expertise in, or control
over the technology infrastructure ‚in the cloud‛ that supports them. It typically
involves the provision of dynamically scalable and often virtualized resources as a
service over the Internet.
Gartner Thomas Bittman Cloud Computing: a style of computing where scalable and elastic IT-enabled
capabilities are delivered as a service to external customers using Internet
technologies.
AMR Research Bruce Richardson, Cloud computing is the next-generation of software as a service, in which a
and esle complete software environment is licensed as a subscription from a software vendor
and low-cost, secure, and dependable IT hardware infrastructure is ‘rented’ from a
utility-computing provider on demand. … (omitted) …
THINKstrategies Jeff Kaplan A set of web-based tools and services which permit users to acquire computing
resources and development capabilities to build or support applications, or perform
specific IT functions on a pay-as-you-go basis.
Enterprise Mark Bowker, ‘Cloud computing’ is nothing more than a service model where business workloads
Strategy Group Steve Duplessie are deployed, transparently executed internally or somewhere on the Internet, and
businesses only pay for what they consume. … (omitted) …
IDC Frank Gens Cloud Computing: an emerging IT development, deployment and delivery
model, enabling real-time delivery of products, services and solutions over the
Internet (i.e., enabling cloud services)
The 451 Group Dan Kusnetzky, ‘Cloud computing’ describes a service model that combines a general organizing
Rachel Chalmers, principle for IT delivery, infrastructure components, an architectural approach and an
and else economic model – basically, a confluence of grid computing, virtualization, utility
computing, hosting and software as a service (SaaS).
Forrester/Jupiter James Staten A standardized IT capability (services, software, or infrastructure) delivered via
Research Internet technologies in a pay-per-use, self-service way.

10. What the $#@! is Cloud Computing
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

11. Cloud Computing Technologies

12. Typical Cloud Computing Platform
• Hosting Platform
• Provides the physical, virtual, and software assets
which include physical machines, operating systems,
network systems, storage systems, power
management, and virtualization software
• Cloud Infrastructure Services(IaaS)
• Abstract the hosting platform as a set of virtual
resources(i.e. compute, storage, and network)
• Manage those resources based on scalability and
availability needs
• Cloud Platform Services(PaaS) • Security Services
• Provide a set of capabilities exposed as a services to • Ensure token provisioning, identity federation,
help with integrating on-premise software with and claims transformation
hosted services • Management Services
• Cloud Applications(SaaS) • Provide a set of capabilities to automate
• Houses applications that are built for cloud scalability and availability administration such

15. Success Cases in Cloud Computing
SmugMug(http://www.smugmug.com/)
• an online photo storage application that stores more than half a petabyte of data on S3
• estimates cost savings on service and storage to be close to $1 million
New York Times(http://www.nytimes.com)
• use EC2 to process terabytes of archival data using hundreds of EC2 instances within 36
hours
37Signals(http://37signals.com/)
• maker of popular online project-management software Basecamp, uses S3 for storage
needs.
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 companies’
systems 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

19. Anatomy of Cloud Computing Technologies

20. Cloud Computing Prospects

21. Prospects for Cloud Computing
• Large enterprises are building their own private clouds to resolve the security
problems
• 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
• Small-sized to medium-sized businesses as well as large enterprises will be run
on the cloud
• Large enterprises will become part-time cloud-computing vendors
• The browser will be all the desktop software you need
• Game services will be one of the most interesting applications of Cloud
Computing
