"Cloud Computing" is a term, which involves virtualization, distributed computing, networking and web-services. It is a way of offering services to users by allowing them to tap into a massive pool of shared computing resources such as servers, storage and network. User can use services by simply plug into the cloud and pay only for what he uses. All these features made a cloud computing very advantageous and demanding. But the data privacy is a key security problem in cloud computing which comprises of data integrity, data confidentiality and user privacy specific concerns. Most of the persons do not prefer cloud to store their data as they are having a fear of losing the privacy of their confidential data. This paper introduces some cloud computing data security problem and its strategy to solve them which also satisfies the user regarding their data security.

Grid computing allows for sharing and coordinated use of diverse computing resources virtually. It provides uniform access to computational resources over the Internet similar to how the web provides access to documents. Key motivations for grid computing include enabling large-scale science through geographically dispersed resources. Grid architectures have fabric, connectivity, resource, collective, and application layers. The Globus Toolkit is commonly used open source software that provides components for security, data management, scheduling, and more. Grids are used in various domains like earthquake and climate simulation.
This document compares and contrasts cloud computing and grid computing. Grid computing refers to cooperation between multiple computers and servers to boost computational power, with a focus on high-capacity CPU tasks. Cloud computing delivers on-demand access to shared computing resources like networks, servers, storage and applications via the internet. Key differences include grid computing having a lower level of abstraction and scalability compared to cloud computing. Cloud computing also has stronger fault tolerance, is more widely accessible via the internet, and offers real-time services through its utility-based pricing model.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. It allows users to access applications from anywhere via the internet using web browsers while data and software are stored on remote servers. Some key characteristics of cloud computing include scalability, device and location independence, reliability, and cost reduction by converting capital to operational expenditures. However, privacy, compliance with regulations, security, legal issues, and potential abuse of cloud resources are some concerns associated with cloud computing.
A Literature Survey on Resource Management Techniques, Issues and Challenges ...TELKOMNIKA JOURNAL
Cloud computing is a large scale distributed computing which provides on demand services for
clients. Cloud Clients use web browsers, mobile apps, thin clients, or terminal emulators to request and
control their cloud resources at any time and anywhere through the network. As many companies are
shifting their data to cloud and as many people are being aware of the advantages of storing data to cloud,
there is increasing number of cloud computing infrastructure and large amount of data which lead to the
complexity management for cloud providers. We surveyed the state-of-the-art resource management
techniques for IaaS (infrastructure as a service) in cloud computing. Then we put forward different major
issues in the deployment of the cloud infrastructure in order to avoid poor service delivery in cloud
computing.

Secure cloud storage privacy preserving public auditing for data storage secu...rajender147
This document proposes a privacy-preserving public auditing system for data storage security in cloud computing. It describes a system with four entities - the data owner who stores data in the cloud, the cloud service provider who provides storage, a third party auditor who verifies the integrity of stored data on behalf of owners, and granted applications that can access the stored data. The system uses secret keys to preprocess and encrypt the owner's data before storage. It allows the third party auditor to efficiently verify the correctness and integrity of stored data through proof of irretrievability protocols, while preserving the privacy of the owner's data. The system aims to ensure data security and privacy during public auditing in cloud storage.

Michael Faraday discovered electromagnetic induction in 1831 through experiments with magnets and coils. His law of electromagnetic induction explains that an electromotive force (emf) is induced in a conductor when the magnetic flux through the conductor changes, either through motion of the conductor or the magnetic field. Fleming's right and left hand rules can be used to determine the direction of induced current or force. Lenz's law states that induced current will flow in a direction that opposes the change producing it.
Some Great Piece Of Art By Mashima
ABOUT THE BOOK
It written and illustrated by Hiro Mashima, Fairy Tail has been serialized in the manga anthology Weekly Shōnen Magazine beginning on August 2, 2006.
In Japan, the fifth volume of Fairy Tail was ranked seventh in a list of the top ten manga.
Fairy Tail was in 2011 the 4th best selling manga in Japan.
It also won the 2009 Kodansha Manga Award for shōnen manga. It has also won the Society for the Promotion of Japanese Animation's Industry Award in 2009 for best comedy manga.
This book is set in a fictional kingdom of Fiore, where magic is a part of life. Magic is bought and sold their everyday and is an integral part of people’s life and there are those who use magic as occupation. They are referred to as wizards or mages.
The wizards belong to various guilds and perform jobs on commission. There are large number of guilds within the country.
In a certain city there lies a certain guild. From which various legends were once born…. Or rather, will continue to be born long into the future….
And its name is…
Fairy tail
“ Do fairies really have tails? Do they even exist... Like them, this place as an eternal mystery... A never ending adventure!”
- true meaning of fairy tail
by fairy tail master Master Makarov
Hiro Mashima
Hiro Mashima(真島 ヒロ,
born May 3, 1977) is a Japanese
manga artist. He gained success
with his first serial Rave, published
in Kodansha's Weekly Shōnen
Manga from 1999 to 2005. His
currently ongoing Fairy Tail,
published in the same manga
since 2006, is experiencing even
greater popularity.
Guilds
There are 3 types of guilds –
Legal guilds
Dark guilds
Independent guilds
The main power in the Kingdom of Fiore is the King and his Government.
Under his order is the Magic Council. When Guilds cause destruction or other disturbances to the peace, it’s the responsibility of the Magic Council. The Council is made up of very powerful Mages, some of whom have the power to legalize or disband Guilds.
Legal and Dark guilds
A Legal Guild is one that has been approved and registered by the Magic Council while a Dark Guild is one that has not been approved by the Magic Council and is treated as a criminal organization.
In general, guilds are formed for individuals to take Jobs and earn Jewels, and also for them to train and grow stronger. Legal Guilds also work to defend against Dark Mages and other criminals.
Guild ranks
Guild master :- A Guild Master is a Mage who is the head of the guild that he or she is affiliated with. Typically, Guild Masters are very powerful, often being the strongest Mage in their guilds.
1. This document provides an overview of fundamental electrical engineering principles including: atom structure, charge, current, electromotive force, potential difference, resistance, Ohm's law, power, and series and parallel circuits.
2. Key concepts covered include that electrons carry charge and enable electrical current, while protons have a positive charge. Resistance opposes current flow. Ohm's law defines the relationship between voltage, current and resistance.
3. Examples are provided to demonstrate calculating current, voltage drops, power, and total resistance in series and parallel circuits using Ohm's law.
Electricity is the flow of electric charge, which is generated from converting primary energy sources like coal into a secondary energy source. Atoms are the basic building blocks of matter and contain protons with a positive charge, neutrons with no charge, and electrons with a negative charge that orbit the nucleus. Electricity occurs when electrons are pushed out of their normal orbits in atoms and move from one atom to another. Electricity powers devices through either series or parallel circuits and is integral to many aspects of modern daily life.

Cloud computing delivers computing services as utilities over the internet, similar to how electricity or water are provided. There are different types of cloud deployment models including public, private, hybrid, and community clouds. Additionally, there are three main service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides virtual computing resources, PaaS provides development platforms, and SaaS provides complete software solutions delivered over the internet. Cloud computing offers benefits like on-demand provisioning, elastic scaling, pay-per-use billing, workload resilience, and migration flexibility.

Cloud computing basically involves delivering hosted services over the Internet to store, manage, and process data, instead of using local server or a personal computer. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). In scientific terms, cloud computing is a synonym for distributed computing over a network which means the ability to run a program on many connected computers at the same time. Therefore it involves a large number of computers that are connected through a real-time communication network.
The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
1. Cloud computing involves delivering computing resources and services over the internet instead of relying on local servers or personal computers. It enables users to access applications and store/process data using remote servers.
2. There are three main types of cloud computing services: Infrastructure as a Service (IaaS) provides virtual computing resources; Platform as a Service (PaaS) offers platforms for developing applications; and Software as a Service (SaaS) delivers fully functional applications over the internet.
3. The main deployment models are public clouds which are owned by third parties and available publicly, private clouds which are dedicated to a single organization, and hybrid clouds which combine public and private clouds.
Public cloud is a cloud computing model where computing resources are dynamically provisioned on-demand via the internet from an off-site third-party provider. It offers flexible resources, scalability, and a pay-per-use model but has less security and customization than private cloud. Popular public cloud providers include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
The document provides an overview of cloud computing, including definitions of cloud, cloud characteristics, common cloud features, deployment models, service models, and examples of major cloud vendors like Amazon Web Services. It discusses how cloud computing provides on-demand access to shared computing resources over the internet and the business benefits of reduced costs and increased flexibility. However, some concerns include data security, latency issues for real-time applications, and lack of control over proprietary systems.

Cloud computing
1.
2. Cloud computing is defined as the practice of using a network
of remote servers hosted on the Internet to store, manage, and
process data, rather than a local server or a personal computer.
The Five Principles of Cloud Computing:-
1. Resources pooling
2. Virtualization.
3. Elasticity.
4. Automatic/easy resource deployment.
5. Metered billing.
3.
4. • There are three types of cloud computing providers-
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS).
• Software as a Service (SaaS).
5. Infrastructure as a Service
(IaaS)
• Infrastructure as a service provides companies with
computing resources including servers, networking, storage,
and data center space on a pay-per-use basis.
• IaaS providers offer hardware and the bare minimum
software for users to develop on e.g. virtual servers, hard
disk space. Users have broad control over the services
offered by IaaS providers as they are able to configure
settings to a very large extent and they are free to implement
and utilize any form of software and programming
environment on top of the services. An example of an IaaS
provider is Rackspace
6. Platform as a Service (PaaS)
• For services offered by PaaS providers, users have very
little control over their software and programming
environment. This is because PaaS providers implement
a software layer over the hardware they offer, forcing
users to work with the providers' software layer. This is
not necessarily a bad thing as PaaS providers reduce the
technical expertise needed for users to create their own
web application.
• Example – Google app engine.
7. Software as a Service (SaaS)
• SaaS providers basically offer software for users over the
Internet through a web browser. An example of a SaaS
is Google Docs, where one can edit documents through
the software delivered over the Internet. The main
advantage of using a SaaS is that you do not have to
worry about installation, storage space, data loss due to
PC crashes or patches - the cloud computing provider
handles all that and simply delivers the software to you
in your web browser.
8. Deployment models
• Public cloud :- Private cloud is cloud infrastructure operated solely
for a single organization, whether managed internally or by a third-
party and hosted internally or externally.
• Public cloud:- A cloud is called a "public cloud" when the services
are rendered over a network that is open for public use. Technically
there may be little or no difference between public and private
cloud architecture
• Community cloud:- Community cloud shares infrastructure
between several organizations from a specific community with
common concerns (security, compliance, jurisdiction, etc.), whether
managed internally or by a third-party and hosted internally or
externally. The costs are spread over fewer users than a public
cloud (but more than a private cloud), so only some of the cost
savings potential of cloud computing are realized.
9. • Hybrid cloud :- Hybrid cloud is a composition of two or
more clouds (private, community or public) that remain
distinct entities but are bound together, offering the benefits
of multiple deployment models. Hybrid cloud can also mean
the ability to connect collocation, managed and/or dedicated
services with cloud resources.
• To be effective, a management strategy for hybrid cloud
deployment should address configuration
management, change control, security, fault
management and budgeting. Because a hybrid cloud
combines public cloud and private data center principles, it's
possible to plan a hybrid cloud deployment from either of
these starting points.
10. Architecture
Cloud architecture, the systems architecture of the software systems involved in the delivery of
cloud computing, typically involves multiple cloud components communicating with each other
over a loose coupling mechanism such as a messaging queue. Elastic provision implies
intelligence in the use of tight or loose coupling as applied to mechanisms such as these and
others.
• The Intercloud
The Intercloud is an interconnected global "cloud of clouds" and an extension of the Internet
"network of networks" on which it is based.
• Cloud engineering
Cloud engineering is the application of engineering disciplines to cloud computing. It brings
a systematic approach to the high-level concerns of commercialization, standardization,
and governance in conceiving, developing, operating and maintaining cloud computing
systems. It is a multidisciplinary method encompassing contributions from diverse areas
such as systems, software, web, performance, information, security, platform, risk,
and quality engineering.
11. Privacy issues
• The increased use of cloud computing services such as Gmail and Google Docs has pressed the
issue of privacy concerns of cloud computing services to the utmost importance. The provider of
such services lie in a position such that with the greater use of cloud computing services has given
access to a plethora of data. This access has the immense risk of data being disclosed either
accidentally or deliberately. Privacy advocates have criticized the cloud model for giving hosting
companies' greater ease to control—and thus, to monitor at will—communication between host
company and end user, and access user data (with or without permission). Instances such as
the secret NSA program, working with AT&T, and Verizon, which recorded over 10 million
telephone calls between American citizens, causes uncertainty among privacy advocates, and the
greater powers it gives to telecommunication companies to monitor user activity.
• Cloud computing poses privacy concerns because the service provider can access the data that is
on the cloud at any time. It could accidentally or deliberately alter or even delete information. This
becomes a major concern as these service providers, who employ administrators which can leave
room for potential unwanted disclosure of information on the cloud.
12. Privacy solutions
• Solutions to privacy in cloud computing include policy
and legislation as well as end users' choices for how data
is stored. The cloud service provider needs to establish
clear and relevant policies that describe how the data of
each cloud user will be accessed and used. Cloud service
users can encrypt data that is processed or stored within
the cloud to prevent unauthorized access.
13. The Future
According to Gartner's Hype cycle, cloud computing has reached a maturity that leads it into a productive phase.
This means that most of the main issues with cloud computing have been addressed to a degree that clouds have
become interesting for full commercial exploitation. This however does not mean that all the problems listed above
have actually been solved, only that the according risks can be tolerated to a certain degree. Cloud computing is
therefore still as much a research topic, as it is a market offering.
• In 2012 the European Commission has issued an analysis of the relevance of the open research issues for
commercial stabilisation in which various experts from industry and academia identify in particular the
following major concerns:
• open interoperation across (proprietary) cloud solutions at IaaS, PaaS and SaaS levels
• managing multitenancy at large scale and in heterogeneous environments
• dynamic and seamless elasticity from inhouse clouds to public clouds for unusual (scale, complexity) and/or
infrequent requirements data management in a cloud environment, taking the technical and legal constraints
into consideration
These findings have been refined into a research roadmap proposed by the Cloud Computing Expert Group on
Research in December 2012 which tries to lay out a timeline for the identified research topics according to their
commercial relevance. With the 8th Framework Programmes for Research and Technological Development, the
European Commission is trying to support the according research work along the lines of the Europe 2020 strategy.
