2. What is Cloud?
Cloud Computing is the emerging concept and technology which
extensively changed the structure of IT industry by decreasing the
requirements of Software's, Licenses, Storage Space, Hardware etc.,
Lets take an example,
Hire Cab
Pay only for the KM’s or Time used
No worry about Maintenance, Finance
Hire Cloud
Pay only for the Services and Usage
No worry about Software's, Licenses, Storage, Hardware etc.,
Storage, Hardware etc.,

3. What is in Cloud?
 Cloud can be both software as well as infrastructure
 Cloud Architecture consists of Front end and Back end and can be
accessed via a web or a server.
Front End
 It’s a client computer can be individual or an organization.
 Client login into the cloud through browser and can be customize
his account based on needs.
 Client is charged on pay-as-you-use basis.
Back End
 It consists of computers, servers, data storage systems.
 Once login cloud middle ware checks the storage, OS, network
availability and provides the required services to the client.

5. SaaS, IaaS, PaaS
Software as a Service (SaaS)
 Providing Software applications as service over Internet
 Eliminates the need to install patches provide security and maintain
it on customers premises.
Infrastructure as a Service (IaaS)
 Providing Infrastructure on Demand
 On demand utilities like server scale up/scale down
Platform as a Service (PaaS)
 Combining SaaS and PaaS
 Delivering computing platform as a Service
 ( A web application with underlying technical components with
Hardware)

7. Benefits
 File Sharing
 Access from devices
 Reduced software costs
 Improved performance:
 Instant software updates
 Unlimited storage capacity
 Increased data reliability

8. What is the purpose?
 Cloud computing enables companies and applications, which are system
infrastructure dependent, to be infrastructure-less.
 By using the Cloud infrastructure on “pay as used and on demand”, all of us
can save in capital and operational investment!
 Clients can:
– Put their data on the platform instead of on their own desktop PCs and/or
on their own servers.
– They can put their applications on the cloud and use the servers within
the cloud to do processing and data manipulations etc.

9. Advantages
 Can be less expensive compared to buying software and hardware
 Can be used from any computer or device with an Internet
connection
 The device does not need as large of an internal storage system
 Compatible with most computers and operating systems
 Updates occur across the service

10. Why is it becoming a Big Deal?
 Using high-scale/low-cost providers,
 Any time/place access via web browser,
 Rapid scalability; incremental cost and load sharing,
 Can forget need to focus on local IT.
 Privacy, security

11. Issues With Cloud
 Requires a constant Internet connection:
 Does not work well with low-speed connections:
 Stored data might not be secure:
– With cloud computing, all your data is stored on the cloud.
• The questions is How secure is the cloud?
 Stored data can be lost:
– Theoretically, data stored in the cloud is safe, replicated across multiple
machines.
 General Concerns:
– Each cloud systems uses different protocols and different APIs
• may not be possible to run applications between cloud based syste

12. Cloud Future
We are still in the early stages of Cloud Computing. Many Researches says that the
grow of Cloud Computing is un stoppable in the near future. To understand this, lets
look few reports from popular research analyst firms published in the last one year,
 Gartner: Cloud computing will become the bulk of new IT spend by 2016. From 2012 through 2017,
across all segments of the cloud computing market, cloud services revenue is projected to have a CAGR of
33.2%, with SaaS and IaaS growth rates projected to be 34.4% and 39.8% respectively
Cisco Consulting Services (CCS): The study surveyed 4,226 IT leaders in 18 industries across 9 key
economies, including 600 from India. Wherein about 83% of respondents in India were “very satisfied” and
another 13% “somewhat satisfied” with cloud, representing a total 96% positive rating.
VMware, Inc. Cloud index: A study, conducted by Forrester Research across 12 Asia Pacific countries,
reveals that nearly 89% respondents in India believe that Cloud Computing, or ‘as-a-service’ approach, is
relevant to their organization and nearly 79% say they currently have a cloud-related initiative in place within
the organization, or are planning to implement cloud, or ‘as-a-service’ approach, in the next 12 months.

13. Cloud Job Opportunities
 Most of the organizations are venturing into the world of cloud computing by
moving some part of their services from the individual user level to cloud
level, resulting in provision of public cloud or private cloud to users.
 This requires a need of “expert group” in the organization not only to create
the cloud, but also to sustain the cloud. This is a new technology and hence
bring careers to many. With the increasing trend to bring more and more
services to the cloud, there exits many job opportunities for fresher as well
as experts.
 Since most of the services or applications can be provided through Internet
or through web services, software development skills such as web services,
AJAX and SOAP, etc. provide more job opportunities.

14. Cloud Research in Migrant
Cloud Computing is the new Buzz word in Education.
Because of its flexibility to create, share, save and collaborate from any
where, any time and any place MIGRANT is embracing the concept of
Cloud Computing for creating flexible learning environments.
In near future devices such as iPhones, iPod's and tablets give access to
these new environments on the go and at the touch of the screen.

15. Conclusion
 Cloud Computing is outpacing the IT industry
 Real business value can be realized by customers of all sizes
 Cloud solutions are simple to acquire, don’t require long term contracts and
are easier to scale up and down as needed
 Proper planning and migration services are needed to ensure a successful
implementation
 Public and Private Clouds can be deployed together to leverage the best of
both
 Third party monitoring services ensure customer are getting the most out of
their cloud environment
