This document discusses secure and practical outsourcing of linear programming in cloud computing. It introduces cloud computing and explains why security is important in the cloud. Linear programming is described as a technique for optimizing allocation of resources that is well-suited for the cloud. The document outlines deployment models, service models, and reasons why cloud computing benefits small businesses, including economies of scale, functionality, and security. Risks to cloud security from data breaches, hijacking, and malicious insiders are also summarized.
In a recent survey of 250 senior IT & business decision makers by Cloud Industry Forum, 61% expressed concerns over data security in the cloud, despite the fact only 2% have ever experienced a cloud-related security breach. Talk of the cloud and cloud technology has been rife for a long time now, yet there
are still many businesses that subscribe to out-dated
myths, such as data security.
The last few years have seen a marked increase in the
popularity of the cloud but for many it’s another tech
innovation that everyone tells them they need but that they
don’t fully understand. There’s a distinct hype surrounding
discussions on the cloud, but for the most part, they come
across as semi-intelligible fog, full of jargon fi lled techspeak,
with a lack of clarity about the business advantages.
In this whitepaper, we’ll lift the haze around the cloud and take
a straight-forward approach to explore the benefits, making it easy to determine if the cloud is right for you. We’ll clearly state the benefits of using the cloud as well as give an overview of the perceived risks and remove some of the common misconceptions.
Cloud computing of late has become the new buzz word joining the ranks of terms including; grid computing, utility computing, virtualization, clustering, etc. However the problem is that everyone seems to have a different definition..
Cloud Computing definition , its history , Service Models , Deployment Models , Architecture, pretty much all the important aspects related to cloud computing
There are many misconceptions surrounding Cloud Computing and what it has to offer.

Zimory White Paper: The Cloud's Slow European Take-offZimory
The term “Cloud” is being increasingly used and analyzed in the IT market. Cloud Services are synonymous with innovative features that clearly differ from the traditional utility computing. Clouds are by definition flexible, dynamic, scalable and heterogeneous, with three defined categories: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). These qualities have proved to be very positive for IT engineering and businesses.
Nevertheless, and because of its novelty, technical and business evolution, the Cloud Computing market presents a certain number of obstacles for companies interested in moving to the Cloud, especially in the early stages.
Decision makers face a sizable considerable number of challenges when considering moving to the Cloud, especially with regards to the following obstacles:
- Pricing policies
- Neutral market place
- Technical standardization
- Lock-in policies
- Data protection and security policies
- Cloud security testing
This paper analyzes these challenges, offering factual, theoretical and practical reasons for the slow take-off of the Cloud Computing market. It also analyzes possible instances to overcome these difficulties, describing Zimory's position and practical solutions to address these market obstacles.
Zimory White Paper: Challenges Implementing an IaaS Cloud ExchangeZimory
The idea of a cloud exchange is a much discussed topic within academic and high-performance computing circles (see Breest, 2007; Buyya, Ranjan, & Calheiros, 2009). The discussion can vary widely based on the type of cloud service being discussed.
Cloud services are commonly divided into three types: IaaS, platform as a service (PaaS) and software as a service (SaaS) (Liu et al., n d). There are several SaaS solutions and services in the marketplace that claim to deliver a cloud brokerage or exchange, however these services integrate SaaS offerings in the cloud rather than the buying and selling of services in their respective domains. This means that a SaaS cloud broker can more accurately be described as an integrator of SaaS services. This offering is completely different from an IaaS exchange from both a business and technical standpoint.
The goal of an IaaS cloud exchange is to create a distributed infrastructure in which different components are interchangeable. Controlled by the cloud exchange, the distributed infrastructure not only increases technical capabilities – such as availability and resilience – it also allows consumers to make economic decisions regarding scheduling workloads. While this is valuable to customers, it also increases the technical complexity of an IaaS cloud exchange compared to SaaS. This complexity means there are currently more SaaS services available than IaaS Cloud exchange services.
The remainder of this paper discusses the challenges, requirements and technology for an IaaS cloud exchange.
Everything you need to know about cloud computing, common characteristics, cloud computing services, cost saving, advantages, deployment models, migrations into cloud and safety and security.
Recent economic pressures have resulted in increased requirements for the availability, scalability and efficiency of enterprise IT solutions.
Many parties claim that “cloud computing” can help enterprises meet the increased requirements of lower TCO, higher ROI, increased efficiency, dynamic provisioning and utility-like services.
However, many IT professionals are citing the increased risks associated with trusting information assets to the cloud as something that must be clearly understood and managed by relevant stakeholders.
This presentation examines the potential business benefits, risks and assurance considerations.
For IT recruiters, and just about everyone who has been interested in tech, cloud is not a new phenomena. However, over the past 18 months, adoption of cloud is growing quickly and is now used in some shape or form by businesses of all sizes around the world.

In this presentation, we discuss the difference between public, private and hybrid cloud; the best practices to use cloud; how to optimise cost and the future of technology.
Over the past few years, businesses have had to step up in their use of technology and the hybrid cloud has become the benchmark of evolution. There are many are still unclear on what the benefits of hybrid cloud are. Every other company is looking to upgrade their systems and embrace the hybrid cloud with a majority registering transitional challenges as the reason they are yet to undertake this transformation. While seeking to understand why, we highlight clear winners in hybrid cloud; you may find it convincing enough to switch to an otherwise mysterious phenomenon. The hybrid cloud does not have a shortage when it comes to lucrative features especially for the business world. We look into some of these features below that are part of the reason why the hybrid cloud is so appealing to all business types.
Enterprise IT is transitioning from the use of traditional on-premise data centers to hybrid cloud environments. As a result, we’re experiencing a paradigm shift in the way we must think about and manage enterprise security. From Four Walls to No Walls Until now, the conventional view on IT security has been that applications and data are safe because they’re physically housed within the confines of a company’s data center walls using company-owned equipment. So, it’s not surprising that many decision makers perceive greater risks as they trade physical assets for cloud-based solutions.
Through our partnerships with leading cloud providers, we are able to offer hybrid, private and public cloud solutions. At Epoch Universal, we supply cloud the way you want it with deep control, extreme performance, and broad customization capabilities. When you join the Epoch Universal fold, you take back the keys to your kingdom. Reign as supreme commander in chief of your cloud. No compromises. No exceptions.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. INTRODUCTION
✦Cloud computing enables customers with limited computational resources to
outsource their large computation workloads to the cloud, and economically
enjoy the massive computational power, bandwidth, storage, and even
appropriate software that can be shared in a pay-‐per-‐use manner.
✦Security is the primary obstacle that prevents the wide adoption of this
promising computing model, especially for customers when their confidential
data are consumed and produced during the computation.
✦Treating the cloud as an intrinsically insecure computing platform from the
viewpoint of the cloud customers.
✦The resulting flexibility allows us to explore appropriate security/efficiency trade off
via higher level abstraction of LP(Linear Programming) computations than the
general circuit representation.
4. WHAT IS CLOUD?
The term Cloud refers to a Network or Internet.
In other words, we can say that Cloud is
something,
which is present at remote location.
Cloud can provide services over network, i.e.,
on public networks or on private networks, i.e.,
WAN, LAN and so on .
Applications such as e-mail, web conferencing,
customer relationship management (CRM),
all run in cloud.
5. WHAT IS CLOUD
COMPUTING?
Cloud Computing provides us a means
by which we can access the applications
as utilities, over the Internet. It allows us
to create, configure, and customize
applications online.
Cloud computing provides a variety of
computing resources , from servers and
storage to enterprise applications such as
email, security, backup/DR, voice, all
delivered over the Internet
6. The Cloud delivers a hosting environment that is
Flexible,
Immediate,
Scalable,
Secure.
Available while saving corporations money, time and
resources.
With Cloud Computing users can access database
resources via the internet from anywhere for as long
as they need without worrying about any
maintenance or management of actual resources.
7. BASIC CONCEPTS
There are certain services and models
working behind the scene making the
cloud computing feasible and accessible
to end users. Following are the working
models for cloud computing:
1. DEPLOYMENT MODELS
2. SERVICE MODELS
8. DEPLOYMENT MODELS
Deployment models define
the type of access to the
cloud, i.e., how the cloud is
located? Cloud can have
any of the four types of
access: Public, Private,
Hybrid and Community.
9.
10. PUBLICCLOUD The Public Cloud allows systems and services to
be easily accessible to the general public. Public cloud may
be less secure because of its openness, e.g., e-mail.
PRIVATECLOUDThe Private Cloud allows systems and services
to be accessible within an organization. It offers increased
security because of its private nature.
COMMUNITYCLOUD The Community Cloud allows systems and
services to be accessible by group of organizations.
HYBRIDCLOUD The Hybrid Cloud is mixture of public and
private cloud. However, the critical activities are performed
using private cloud while the non-critical activities are
performed using public cloud.
11. SERVICE MODELS
Service Models are the reference
models on which the Cloud
Computing is based. These can be
categorized into three basic service
models as listed below:
1.Infrastructureasa Service(IaaS)
2. Platformasa Service(PaaS)
3. Softwareasa Service(SaaS)
12. Infrastructure as a Service (IaaS)
IaaS is the delivery of technology infrastructure as
an on demand scalable service.
IaaS provides access to fundamental resources
such as physical machines, virtual machines,
virtual storage, etc.
• Usually billed based on usage
• Usually multi tenant virtualized environment
• Can be coupled with Managed Services for OS
and application support
14. Platformas a Service (PaaS)
PaaS provides the runtime environment for
applications, development & deployment tools,
etc.
PaaS provides all of the facilities required to
support the complete life cycle of building and
delivering web applications and services entirely
from the Internet.
Typically applications must be developed with a
particular platform in mind
• Multi tenant environments
• Highly scalable multi tier architecture
16. Software as a Service (SaaS)
SaaS model allows to use software
applications as a service to end users.
SaaS is a software delivery methodology
that provides licensed multi-tenant
access to software and its functions
remotely as a Web-based service.
Usually billed based on usage
• Usually multi tenant environment
• Highly scalable architecture
19. LINEAR PROGRAMMING
Linear programming is a widely used mathematical modeling
technique to determine the optimum allocation of scarce
resources among competing demands. Resources typically
include raw materials, manpower, machinery, time, money and
space.
The technique is very powerful and found especially useful
because of its application to many different types of real business
problems in areas like finance, production, sales and distribution,
personnel, marketing and many more areas of management.
As its name implies, the linear programming model consists of
linear objectives and linear constraints, which means that the
variables in a model have a proportionate relationship. For
example, an increase in manpower resource will result in an
increase in work output.
20. WHY CLOUD COMPUTING ?
✦Cloud Computing is very much useful to a smaller
companies to generate similar savings and
capabilities on its own.
✦Many of the issues blamed on the cloud in large
enterprises - security, integration, compliance and
so on - often cause fewer problems in small
companies that can't properly deal with them
anyway.
MAIN REASONS WHY CLOUD COMPUTING IS BETTER FOR SMALL
BUSINESSES
ECONOMIES OF SCALE
ENTERPRISE CLASS FUNCTIONALITY
MONEY MATTERS
INFRASTRUCTURE APPLICATIONS
SECURITY PROBLEM
COMPLIANCE
RELIABILITY
21. 1.Economies of scale: This one's obvious. The larger
the company, the easier it can generate economies of
scale on its own. Small companies, by definition, have
more limited resources. Anything that can give them
access to scale in purchasing and pricing is a big win!
2.Enterprise-class functionality. Big companies have
the heft to create the custom functionality they need.
Small companies simply don't have the resources to do
that. In the cloud, though, they can leverage
development, maintenance and upgrades across many,
many small businesses... And, increasingly, consumers
as well.
3.Money Matters. Startups and small companies are
often under capitalized and pay-as-you-go cloud
computing solutions typically don't require lots of upfront
cash. Even if they don't end up saving much as the
monthly fees add up over the long run, avoiding capital
expenditures can be a make-or-break issue for cash-
strapped small businesses.
Reasons why cloudcomputing
22. 4.Infrastructure vs. Applications. For the enterprise, cloud
computing often means complex Infrastructure as a Service
(IaaS) projects that have to be installed and integrated into a
company's existing systems. For smaller companies, cloud
computing often means complete cloud-based Software as a
Service (SaaS) applications and application suites. No IT
required.
5.Security Problems. I'm not saying security isn't important
to small businesses (though many don't take it as seriously
as they should). I'm saying that while security in the cloud
may still be shaky by enterprise standards, it's almost always
far better than what small businesses are able to provide for
themselves.
23. 6.Compliance. Because you don't necessarily know
where your data is stored in the cloud, IaaS can cause
confusion as to whether it complies with local, national
and international regulations. That's a huge issue for
multinational corporations, less so for most small
businesses.
7.Reliability. The cloud is more reliable than most
people think. When widely used cloud services and
applications have outages, it makes national news.
When an individual company - large or small - has a
similar problem, they work hard to make sure you never
even hear about it. The bottom line, though, is that even
accounting for network connectivity hiccups, the cloud
is probably a lot more reliable than what small
businesses can afford to provide for themselves.
24. WHAT IS SECURITY ?
Security is the degree of resistance to, or protection
from, harm. It applies to any vulnerable and
valuable asset, such as a person, community,
nation, or organisation.
✦Cryptography
✦Redundancy
✦Disposal
✦Transfer security
✦Firewalling
What exactly firewall does is:
It isolates the virtual machines . Brilliantly
filters addresses and ports
Prevents Denial-of-Service (DoS)
Detects external security assessment
measures
25. Whysecurity is needin cloud computing?
"The Notorious Nine," the top nine cloud
computing threats has been identified by the
CSA (Cloud Security Alliance).The report reflects
the current consensus among industry experts
surveyed by CSA, focusing on threats specifically
related to the shared, on-demand nature of cloud
computing.
The top most threats to the cloud computing are :
✦Data Breaches
✦Data Loss
✦Account or Service Traffic Hijacking
✦Insecure Interfaces and APIs
✦Denial of service
✦Malicious insiders
✦Abuse,
✦Insufficient due diligence
26. Outsourcing computation to the commercial
public cloud is also depriving customers’ direct
control over the systems that consume and
produce their data during the computation, which
inevitably brings in new security concerns and
challenges towards this promising computing
model.Theoutsourced computation
workloads often contain sensitive
information, such as
✦The business financial records,
✦Proprietary research data,
✦Personally identifiable health information
etc.
EXISTING SYSTEM
27. ✦ End to end data confidentiality
✦unauthorised information leakage
✦sensitive data have to be encrypted before
outsourcing
How ever,Ordinary data encryption techniques in
essence prevent cloud from performing any meaningful
operation of the underlying plaintext data making the
computation over encrypted data a very hard problem.
There are huge financial incentives for the cloud to be
“lazy” if the customers cannot tell
✦The correctness of the output
✦Possible software bugs
✦Hardware failures,
even outsider attacks might also affect the quality of the
computed results.
DISADVANTAGES
28. PROPOSED SYSTEM
Our Linear Programming outsourcing
scheme which
provides a complete outsourcing solution for not
only the privacy protection of problem
input/output, but also its efficient result
checking. We start from a secure LP outsourcing
design framework.
ADVANTAGES
✦Optimal solution using LP problems.
✦Better security on both uploading and
downloading.
✦Integrating mathematical implementation
in encryption

30. Mechanism Design Framework
These four algorithms are summarised below :
•KeyGen(1k ) → {K }. This is a randomized key generation algorithm which takes a system security
parameter k, and returns a secret key K that is used later by customer to encrypt the target LP
problem.
• ProbEnc(K, Φ) → {ΦK }. This algorithm encrypts the input tuple Φinto ΦK with the secret key
K. According to problem transformation, the encrypted input ΦK has the same form as Φ, and thus
defines the problem to be solved in the cloud.
•ProofGen(ΦK ) → {(y, Γ)}. This algorithm augments a generic solver that solves the problem ΦK to
produce both the output y and a proof Γ. The output y later decrypts to x, and Γ is used later by the
customer to verify the correctness of y or x .
•Result Dec (K, Φ, y, Γ) → {x, ⊥}. This algorithm may choose to verify either y or x via the proof Γ. In
any case, a correct output x is produced by decrypting y using the secret K. The algorithm outputs ⊥
when the validation fails, indicating the cloud server was not performing the computation faithfully.

38. CONCLUSION
✦The problem of securely outsourcing LP computations in cloud computing,
and provide such a practical mechanism design which fulfils input/output
privacy, cheating resilience, and efficiency.
✦By explicitly decomposing LP computation outsourcing into public LP solvers
and private data, our mechanism design is able to explore appropriate
security/efficiency trade offs via higher level LP computation than the
general circuit representation.
✦This develops problem transformation techniques that enable customers to
secretly transform the original LP into some arbitrary one while protecting
sensitive input/ output information.
