Now a day even though Cloud services offer flexibility, scalability, there have been proportionate concerns about security. As more data moves from centrally located server storage to the cloud storage. Security is the most important factor related to the cloud computing. As the users can stores his private data on cloud with the help of cloud service providers. Data stored on single cloud is risk of service availability failure due to attacker enters in single cloud.
Our approach is to movement towards multi-clouds that is data stored on multi-cloud service providers. In this system we propose a secured cost-effective multi-cloud storage (SCMCS) model in cloud computing in which holds an economical distribution of data among the available cloud service provider (SP) in the market, instead of single cloud to provide customers with data availability as well as security. This work aims to encourage the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user. Our proposed model provides a better security for customer’s data according to their available budgets from that they can choose cloud service provider.

1. INTRODUCTION
Cloud computing is nothing but rate server and internet based model .A huge amount of data being retrieved from geographically distributed data sources and non localized data handling requirements. The industrial information technology towards a subscription based or pay-per-use service business model known as cloud computing. One of the advantage of cloud computing is cloud data storage, in which users do not have to store his own data on their own server...

Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access
...idence of users by agreeing to the policy that the data submitted to their cloud platform will be kept confidential. (Ryan, 2011)
The author appear to be moderately perplexed by the fact that American state that they are concerned about privacy but they yet disclose personal information to entities. I would offer that the reason many are disclosing the information, is that business will not offer their services or product without the personal information. One can go to another vendor for service, only to have the same problem repeated. Now what is perplexing, is the authors claim that “a significant number, 11%” (Caftori & Teicher, 2002) of the population believes that corporate owners should go to prison for violations of information privacy. I must say, I never thought of 11% of a population as a significant percentage, but I am just a student. More confusion for the authors is when a computer system that handles big data has faulty output. They use the analogy of an airline, and if they lose your luggage and should receive compensation, but this is not the case when the DMV provides faulty data. This should not be perplexing, with the airline an explicit contract is made with the purchase of the ticket. The airline is transport my body and my luggage to the agreed location without damage or loss. Luggage is tangible. The contents are worth x amount of dollars and the airline pays the individual

When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.

The computer is considered one of the most important technological advances of the twentieth century. Security and privacy issues have been in existence long before the computer became a vital component of organizations' operations. Nevertheless, the operating features of a computer make it a double-edged sword. Computer technologies with reliable error detection and recording capabilities, permit the invasion of a supposedly secure environment to occur on a grand scale and go undetected. Furthermore, computer and communications technology permit the invasion of a persons' privacy and likewise go undetected. Two forces threaten privacy: one, the growth of information technology with its enhanced capacity for surveillance, communication, computation, storage and retrieval and two, the more insidious threat, the increased value of information in decision making. Information has become more vital in the competitive environment, thus, decision makers covet it even if it viol!

Cloud computing services provide a multitude of benefits for businesses of every size. Cloud computing services offer “flexible computing power and data storage, as well as data management, messaging, payment and other services that can be used together or individually (Laudon 2014). The list of benefits is long and varied. Cloud computing services are universal. Anyone and everyone can use the system. Cloud computing is cost effective. There is no maintenance fee, but rather a business pays for what they use. The amount of storage space is unlimited. This is a boon to companies who cannot accurately predict data usage. The ability to access private and public clouds ensures stability and security.

Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.
