Cloud computing is a releasing individual and institutions from the traditional cvcle of buying-using-maintaining-upgrading IT resourcs - both hardware and software. Instead it is making IT resource accessible from anywhere and at proportions as required by the end user. Here is a brief introduction to this new transformation

3. Cloud Computing: Simplified
Cloud computing is a model of delivering computing
resources from the Internet to the user.
Computing resources:
Software- Applications, OS, service
Hardware ( processors, servers, memory, cards)
information - encyclopedia, search engine
User
computer connected to the net
mobile user
Connected TV

4. Cloud service - An example
when you get connected to service like Gmail, Hotmail
etc - you are really connecting to a massive pools of
servers somewhere out there on the internet

5. Why is it called Cloud Computing ?
Because in network diagrams, the Internet is depicted as a
cloud

7. Cloud Resources

8. Technical Definition
Cloud computing is a model for enabling convenient,
● on-demand network access to a shared pool of
configurable computing resources (e.g., networks,
servers, storage, applications, and services)
●that can be rapidly provisioned and released with
minimal management effort or service provider
interaction.

11. How will it help User (me & u) ?
●Cloud will emerge as a major source of all our computing
resources
●IE 9 and Chrome OS- an operating system built around a
web browser

town and want to find a
accommodation for yourself?
What are u options ?

23. Build a New house ( IaaS)
Difficult, time consuming

24. Infrastructure as a Service (IaaS)
●Vendor provides
○ VM,
○Storage and
○Computations
●Target:
○Developers and ISV
●Examples
○Amazon
○Smugmug- a paid digital photo sharing service

25. Renting/buy a House (PaaS)

26. Rent or buy a house
Furnishing is u r freedom

27. Platform as a Service (PaaS)
●Vendor provides higher level API
○ hides machines, storage etc
●Target: Developers and SME
●Vendors: Force.com, Google AppEngine

28. Stay in a Hotel (SaaS)

29. Software as a Service ( SaaS)
Business software delivered through cloud
Target:
SME & Enterprise
Vendors:
Google, Microsoft, Salesforce
MS word, Docs, spreadsheets, CRM

35. Cloud Computing
Concepts

36. Concept of cloud computing
●A concept is an instrument and a history, that is
a bundle of possibilities and obstacles
involved in the world as experienced – quote G
S Granger
●Instrument - Using net as the source of computing
resources and delivering them directly to the user
●Bundle of possibilities
○SAAS, IAAS
●History – Grid Computing, Distributed computing
●Obstacles - security, connectivity

37. Idea of Utility
water, electricity , petrol ...

38. Conceptual Foundations
●Cloud computing concept has been derived from the Utility
computing model.
○The Best example Utility computing ( Packaged,
metered) model would be the electricity supply system
and another concept which it depends on is the Grid
computing model.
○Cloud computing has been mainly derived from the
Mainframes concept.
○The main feature of cloud computing is the scalability
and how it incorporates a part of virtualization.

39. Concept- Business
●Utility Computing- packaged, metered
●Produce in large supply in retail
○ Water
○ Electricity
●Whole buy- retail sale
●Build large and massive capacity and
service is in and through individual
units/users
○per MB

40. Paradigm
●Direct to U From the “ net” as
against “on premise” ( DTH)
●Direct to user – TV channel subscription
●Use without owning- Ramco OnDemand
Cloud
●Rental basis- Google for Enterprises
●Procure as u grow (Gmail start with 7GB
and ask for more )
●From NIL to FULL

41. Why cloud Computing is
a compelling paradigm

42. Cloud Computing-
Innovations
Advantages

43. Scalable Architecture
●Scales up to meet Business Goals
●Grids to handle fail-over, backup, disaster
recovery & scalability
○Computing grid: for serving user requests
○Storage grid : File grid, Database grid
○Messaging grid: for real-time updates and chats

44. Superior Integration
●Integration across SaaS applications is far easy
○CRM integrating spreadsheet and email
●Small web services & aggregation (SOA)
○Evolve each service independently and rapidly
●Contextual integration- application + user's data
and context

45. Performance
Cloud gives better performance
●Caching
○HTML Page caching
○distributed server side object caching
○convert dynamic data into pre-computed static
content
● For example
○Zoho Sheet ( online spread sheets) can be
faster than loading complex Excel documents

46. Conclusion
●Cloud represents a new found land-
migrate as early as possible
●Cloud computing represents a new
Trend- embrace it
○It better to go with trend than to fight it
○More people learn on web

64. Enterprise computing
● Enterprise computing is the application of computers for data
processing activities in an organization. The resulting systems are
called Information systems(IS).
● Enterprise Computing started with the advent of mainframe
computers in the 60's. Over the years with the introduction of new
computing devices, enterprise computing paradigm have
transformed into new models- changing in scale and ubiquity.
○ mainframe
○ PCs, client-server models
○ Internet - web-based enterprise computing and customer-facing
e-commerce models
Cloud Computing has new potential for revolutionizing enterprise
computing once again. This is happening in our Times more

65. Elements of Cloud Computing
The elements of Cloud computing are
1. computing resources packaged as a commodity and made
available directly from the Internet ( UTILITY)
2. the ability of the end-user to rapidly provision the resources
they require
3. metering - a pricing model that charges the user only for the
actual consumption of resources
4. advantage of exploiting of economies of scales by cloud
computing provider
more

66. Consequences of Cloud Computing
Cloud provider such as Google or Microsoft set up
concentration of massive clusters of computing resources-
opens up possibilities for large scale data analysis at scales
unheard until the advent of cloud computing.
This new challenge has resulted in the development of new
programming models and development tools to enable large
scale computations and development productivity
