CHAPTER 1 INTRODUCTION 1.1 Background Cloud computing allows a group of services and networks which work together to provide storage and information. Cloud computing means resource offered as a rental over the Internet instead of storing information on your own drive you can directly use it on the Internet without downloading it. Take an example of a software organization where a customer asked for an application with java platform to fulfill the customer requirement. We cannot by the whole software investing so many bugs instead we can rent it online using cloud. Which is cost effective. Research towards cloud computing is receiving a lot of appeal from both scholastic and manufacturing sectors. Clouds can provide many types of services like maps, games etc., and infrastructures like nimbus and like windows azure. Data stored in cloud is highly confidential like data related to medical records and social networks. Security and privacy of such data is very important. Users should be provided with valid authentication as the data is very confidential. User privacy is also required so that there is no data leakage. We should also protect the cloud from hackers. In server clouding attack, the files in the cloud can be modified. To protect the cloud from these attacks the data should be encrypted. Efficient search should also be provided for encrypted cloud storage. The cloud should not have a self-query but should provide relevant
Cloud computing is one of the fastest growing segment of Information technology today. In simple words cloud computing means storing and accessing data and programs over the internet instead on the computer's hard drive which can be accessed from any part of the world if the individual are connected to the internet or a network connection is available 24/7. A simple example of cloud computing is g-mail. With the connection of internet through any medium we can send and receive emails.
This research paper clearly explains the concepts of what is cloud computing and its evolution and components of clouds in which it categorizes. Models are included in the cloud computing these are also explained in the paper and also more benefits occurs in cloud computing. Security is very important when the sensitive data is lying in cloud and the risks to the cloud are enormous. The important points to be considered when a corporate organization is planning to move its data and applications to the cloud computing are Restricted user access, Regulatory compliance, Data Position, Data Separation, Recovery, Support, Long-term viability. Some Future aspects are also discussed in order to manipulate the present environment.
Cloud computing refers to a computing environment where software and storage are provided as an internet service and accessed with a web browser.
Cloud Computing is a type computing that shares resources both hardware and software over the internet rather than sharing it over a local server . Users can access cloud based apps through a web browser or an mobile or laptop which makes things alot easier for the user. Lots of companies use cloud computing such as Xbox 360, there online cloud data service allows users to use their Microsoft accounts anywhere.
Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.
Cloud computing is expected to be one of the major Information Systems trends in 2009. Weinberg lists cloud computing among his Nine Hot Technologies for 2009 (2008, p. 5). He describes three levels of clouds. The first level is infrastructure in the cloud. The
The future of computing is slowing turning to the cloud. Eventually, most individuals and companies will be utilizing the cloud. Businesses can use high quality cloud computing, grow as needed, without having to spend a lot of capital. Cloud computing offers the flexibility of meeting on demand computing needs along with system availability, performance and security features. Cloud computing is faster and less expensive as they would only pay for what is used.
The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.
In computer networking , cloud computing is computing that involves a large number of computers connected through a communication network such as the Internet , the same as utility computing . In science , cloud computing is a synonym for distributed computing over a network, and that means the ability to run a program or application on many computers connected at the same time .
Cloud computing refers to the delivery of computing services over the internet. The computing services include: infrastructure, development platforms and software applications. Cloud services are privately owned for the purpose of remotely provisioning scalable and measured IT resources from data centers located around the world.
Cloud computing can be defined as the large-scale, shared IT infrastructure which is available over the internet it helps is transforming the way corporate IT services are delivered and managed.

What is Cloud computing? Cloud computing refers to the practice of using software and hardware resources at remote location using internet. Thus cloud computing enables user to rely on such resources on a cloud for processing and storage needs and pay as per usage. One of the most important
Cloud computing is storing and accessing data and programing over the Internet instead have on your computers hard drive. This makes everything physically close to you, which makes data access fast and easy without carrying around an usb. Although, the computer industry has operated under a local storage system for decades some still favor the old way because the cloud doesn’t have dedicated network attached storage hardware in residence. For it to be cloud computing you need to have access to your data or your programs over the Internet and synch it along with other information over the Web.
INTRODUCTION: Scientific Computing solves major issues and problem in a whole range of domain and it provides vast knowledge and
