4. Clouds and Case studies
 Cloud is just a internet based: email exists some where
on some machine, I do not know where the exist.
 We have some servers that store email, videos, pictures,
any thing else. where is that server and where exist we
don’t know.
 That data is stored on cloud on some server or server of
servers.
 When we want data just access the data with internet its
available for me. this is the power of cloud.

5. Case studies…….
• Feb.21,2011 during ICC WORLD CUP,
INDIA
• Everyday 10:00 am to 11:00 am ,since ?
Till date, online ticket booking-IRCTC,india
• May 2009,india jumbo general election.
• A website launched by french first lady
Carla Bruni has crashed on its first day.

6. Soln. of above scenarios
 Add more servers to balance the load(load
balancing).
 Buying servers is a compound problem of
companies/organization that are already
on tight budget.
 In case if companies are financially strong
then adding thousand of servers to handle
a few days in traffic is homogenous waste
of resources.

7. Cloud computing
 It is a internet based computing.
 Customers plug into the “cloud” to access
it resources which are priced and provide
“on demand”essentially,these IT resources
are accessible and shared among multiple
users.
 Cloud computing combine
virtualization(one computer hosting
several virtual servers”)

8. Cloud computing contd….
 Thus it offers three things….
i. Dynamism: your need is dynamic,so
should be your infrastructure to support
the changing needs.
ii. Abstraction: from an end users
perspective,they do not need care of o.s.
the plugins,web security or s/w plateform.
iii. Resources sharing: provide the flexibility
to share applications as well as other
network resource such as hardware.

9. Cloud computing contd….
 Essential characterstics
I. On demand self service: computing capabilities can be provisioned by the end user
without any help from the the support team of the service provider.
II. Scalable and elastic: any cloud service must be size up or size down based on
applications demand and the users base.
scalability is the ability to automatically grow ar shrink.
elastically is how instantly an application can add or remove resources.
iii. Resource pooling: achieved by multi-tenant application architecture.
iv.Use internet tech.: must be accessible through internet.
 Service models
i. SaaS: service provider has a very administrative control on the application and is
responsible for update, deployment, maintenance and security. Eg. Gmail
ii. PaaS: paas is a plateform where s/w can be developed, tested and deployed.
iii. IaaS: require of virtual computers, cloud storage, h/w infrastructure components like
firewalls and configuration services.
 Deployment models
i. Private cloud: cloud infrastructure is operated solely for an organization.
ii. public cloud: made available to the general public.
iii. Community clouds: shared by several organizations.
iv. Hybrid cloud: combination of two or more clouds.

10. Abstract
 Now a days, cloud computing is not beneficial for business activities but it is
also used in universities, academic institutions and private organizations.
 Cloud computing in academic environment will be benefitted by every
student and staff where safety of data is needed in academic.
 Universities have various departments and no. of students with increased
volume of data, then how we manage these data regularly and provide up to
date information to students, faculties and other organizational activities.
 Creating a private cloud will be beneficial for university. Use of private cloud
for university has many benefits such as e-mails Databases, educational
resources and tools for faculty, administrators and staffs and other users on
demand. they reduce the cost of power, electricity and air conditioning.
 The implementation of private cloud computing will help the universities by
reducing the expenditure cost with decreasing their demand for software
licensing and it has operational benefits.
 Private cloud reduces university IT complexity and cost.

11. Introduction
 The universities all over the world are under increasing pressure to employ the
Information Technology (IT) for the welfare of faculty members, students, operational
staff and management. The different stakeholders of a university like students,
parents, employees, management, and administrators are continuously engaged in
the process of educational planning, growth and other activities.
 In order to provide various facilities to the students, faculty, management and for the
operation, the university needs storage and computing system that would integrate
multiple services and concerned request..
 However, the universities in India are facing a number of challenges related to their
management due to increased number of students.
 There are also some other reasons which rather obligated them to find appropriate
storage solution for the universities like…
i. Every time the data is transferred for storage should be well encrypted for security
reasons and safe storage.
ii. A continuous process is required to provide new backups as the file changes.
Whenever there is some change in the file, the particular change needs to be backed
up and not the whole file.
iii. Since the university also includes students, teachers from non-computer
background, so the accidental deletion of the file may be regular phenomenon.
There must be some provision of getting the file back even if it is deleted from PC.

12. Literature review
 Mehmet Fatih Erkoç, Serhat Bahadir Kert : they tried
to show that the Cloud Computing can also be used for
universities. The main goal of suggested prototype is;
managing effectively the technological needs of
universities such as delivery of software, providing of
development platform, storage of data, and computing.
 Ajith Singh. N, M. Hemalatha (2012) they tried to show
that Lots of crisis has happen in business world as well
as in academic environment. Data security, storage,
processing power is limited while using traditional
computing. Data are also in risk and not available all
time. Due to cost many couldn’t fulfill the availability of
resource to student and staff by using cloud computing
in academic environment we can solve all the issue.

13. Contd…
 Silky Bansal, Sawtantar Singh, Amit Kumarey(2012) they
propose different views and solutions in the area of cloud computing
infrastructure for academic institutions.
 The main goals of this prototype are: to share existing resources
and to improve the level of computer science education in present
courses by implementing new technological solutions in Software
Engineering projects, database management administration and
development, systems analysis and design, networking and
programming.
 Sara Qaisar and Kausar Fiaz Khawaja(2012) They propose
Network/security issues related to the cloud computing environment.
Networks structure faces some attacks that are denial off service
attack, man in the middle attack.

14. Problems
 Universities in india are facing a lot of challenges related to their
management due to increased number of students. Increasing no. of
students is a factor of increased large volume of data. The different
stakeholders of a university like students, parents, employees,
management, and administrators are continuously engaged in the process
of educational planning, growth and other activities. In order to provide
various facilities to the students, faculty, management and for the operation,
the university needs storage and computing system that would integrate
multiple services and concerned request.
 Problem of power consumption, the air-conditioning and electronic waste
that can be caused by number of datacenters.
 facing the problem of pay for infrastructure, and cost for taking licensesd
software.
 security and privacy in data using some encryption techniques,
authentication and authorization.

15. Objective of thesis work
 Our main objectives of thesis is to creat a private cloud
for any university that will reduce the expenditure cost
with decreasing their demand for software licensing and
it has operational benefits.
 And then we deploy some applications in this cloud and
also provide some security aspects like authentication
and authorization and some encryption techniques.
 Thus the university needs not pay for infrastructure, they
simple pay for how much they transfer and save on the
providers server.

16. Security issues private clouds
 Authentication
 Integrity
 Confidentiality
 Availabilty
 Authorization
Attacks in private clouds
i. At security level: brute force attacks, password cracking.
ii. At management level: encryption, tampering,side channel attacks.
iii. At application layer: sql Injection, connection pooling.
iv. At client level: session hijacking.
v. At service delivery level: denial of service, encryption.

17. Research methodology
 Platform- .net framework 4.0
 Frontend- asp .net
 Backend- sql server
 security mechanism through C#
 Developing applications with windows azure.
 Virtulization:
i. Virtualization is creation of something rather than “virtual”(rather than actual).
ii. in the physical server we install a small operating system called hypervisor. the
magic is that this very small highly efficient operating system allows you to install
other guest operating system beneath it .
iii. the hypervisor controls these other guest Os installations called (virtual servers)
and allows them to share all resources without interrupting each other. in the case
of multiple physical servers, they were consolidated into one virtualized physical
servers. this server would then rum multipal virtual servers instancs representing
the original physical servers. The result is highly efficient server with a utilization of
80%-90%.

18. Conclusion
 The implementation of private cloud computing will help
the universities by reducing the expenditure cost with
decreasing their demand for software licensing and it
has operational benefits.
 Private cloud reduces university IT complexity and cost.
 Computer in academic environment must have the latest
hardware and software. Due to cost many couldn’t fulfill
the availability of resource to student and staff by using
cloud computing in academic environment we can solve
all the issue.
