Research Paper On Cloud Storage

Cloud Computing has given rise to variety of recent innovations by giving much flexibility to use resources and services at very low initial cost. Now a day’s most of the business organizations and companies move towards the cloud computing due to increases demand of resources and services as the business grow. In this paper different types of challenges are discussed that should be considered while adopting the cloud computing technology.

Cloud because of its wide range of applications it allows users to store data their data remotely in the cloud and enjoy the on-demand high quality cloud applications and reveal burden from the local storage, cost and maintenance. In this according to the user’s perspective, including both individuals (private) and enterprises like companies appealing the cloud benefits by storing data remotely into the cloud in a flexible on-demand manner and relief of the burden of storage management along with this he/she can also enjoy the universal data access which dependent geographical locations and avoidance of the capital expenditure, software, hardware and personnel management and maintenances and so on.

The economic case for cloud computing is compelling and at the same time there are striking challenges in its security. The concepts of cloud computing security issues are fundamentally new and intractable. What appears new is only relative to traditional computing that has been practiced since several years. Many such security problems have been giving attention since the time-sharing era. Cloud computing providers have and can build datacenters as large due to their expertise in organizing and provisioning computational resources at as low cost as possible.

Cloud storage is a new concept based on cloud computing, it is a model of data storage where the digital data is stored in logical pools, the physical storage spans multiple servers (and often locations), and the physical environment is typically owned and managed by a hosting company. These cloud storage providers are responsible for keeping the data available and accessible, and the physical environment protected and running. People and organizations buy or lease storage capacity from the providers to store user, organization, or application data. So cloud storage is a cloud computing system that aims on storing and managing data.

The Cloud is in fact a broad set of computers that are connected to each other and act as a single ecosystem. The cloud has been configured to provide one or more types of services (such as data storage, content delivery, or applications) so that users can remotely access these services.

By introducing the intense programming which were extremely difficult to hack the servers move toward becoming more secure however it includes certain financial costs furthermore for the organizations which were eager to upgrade to such security components. Centralization is likewise one more factor that makes the cloud innovation the most secure one as it guarantees the simple control particularly to the customers of PaaS and IaaS models. Cloud security is centered around the single area on the primary server which is much better than the idea of individual organizations controlling the security of various servers at various areas. Through cloud security better treatment of the framework in a sheltered and secure way is accomplished. In organizations, if business is coordinated with the cloud administrations they may confront bring down dangers and enhance responsibility and kept up since the cloud specialist co-op is in charge of taking care of the whole thing. Therefore, the business require not to have money related incurrence and due to this reason it is important to pick the most committed organization to give the administrations, further developed safety efforts should have been actualized. The organizations in a need to guarantee development via completing the profound examination with respect to the

However companies providing cloud computing services counter argue to this say that they live and die by their reputations. Customers pay these companies because they are trust worthy in security measures. Otherwise, they would lose their clients. It's their job to provide best services to their clients. Privacy is the other issue. The data can be accessed from any location; it's possible that the client's privacy could be weakened. One way to solve this problem is by using proper authentication techniques. Another solution is to provide authorization so that each and every user can access only the data relevant to his/her job. Copy time and costs also play an important role. How fast can the data be copied is important for data resiliency. Reliability is also an issue [21].

Several researchers have addressed the issue of depending on a single cloud storage service, such as cite {AbuLibdeh2010} cite {Scalia}, and they believe that adopting multiple cloud storage services is a useful approach to tackling the problems associated with the dependence on a single cloud provider. Simply, This method combines several independent cloud services and considers them as one cloud. Although the distribution of data among several cloud storage services increase availability, performance, and reduces the probability of losing data, it may increase the amount of storage and bandwidth used and as a result, the cost rises. Scalia cite {Scalia} introduced a cloud brokerage solution that continuously adapts the placement of data, based on files access statistics among several cloud storage services to minimise the storage cost, improve the data availability, and eliminate vendor lock-in risk. However, The work does not evaluate the impact of the system on the latency time. HAIL cite {Bowers2009} used the principle of RAID to distribute files across a collection of cloud storage to enhance the availability of data and remotely manage data security risks (i.e. data integrity) in the cloud by employing the Proofs of Retrievability (PORs) system. Although this work shows a reduce in storage cost, they do not consider the effect of access patterns on the network cost. Besides, they assume that

Cloud computing has provide the software and services the demand of the client. It offer the client to connect to computer resources and access the resources with a previously unknown level of ease because of this new cloud become the new ground of development of a generation of delivering service and store the privacy and security may be include security concern among user of the cloud have become concern of cloud.

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Cloud computing is a technology that provides practice of applications and services over a remote servers, which means you can use a remote server to store, process and manage your data rather than buying your own server. Cloud computing is a rising technology now a day’s every big organizations are adopting cloud in their services due to its vast benefits and also it has numerous potential profits to the associations by creating a service which is very simple and easy to maintain. By introducing cloud service in the organization will simplify many issues related to the security, computer networks and other services which are served online.

Cloud computing is regarded as one of the most rapidly developing technologies in the present world and giving superb solutions to the small and medium sized enterprises with remarkably low cost. The data of the entrepreneurs is stored in the cloud servers and accessed by the users of the company. But there is reasonable doubts are instigating the users of the cloud computing data availability, confidentiality and the security. Cloud Computing has become famous because of the low cost and customizable business needs to be provided with its three basic services IaaS, PaaS and SaaS. Many research works have been done to incorporate a strong security to prevent the possible threats in cloud computing. The securities incorporated in cloud computing for data security, Application security and transactional security. In developing the security the relative analysis has to be done, a suitable frame work has to be instigated and a novel approach has to be followed for the management of security in cloud computing. In establishing the security the architecture of cloud computing has to be taken care in relation with SAAS, PAAS and IAAS implementation

Cloud computing is a complex infrastructure of software, hardware, processing, and storage that is available as a service. Services range from the sublime—financial analysis, medical information and diagnoses, and document creation and collaboration—to the whimsical—computer gaming.

Security Issues : There are many challenges in the area of cloud computing and security is one of them. Increasing the level of security is required for improving the quality of cloud based services. Location of data is a important factor in the security of cloud based computing. Transparency of the data location provides the flexibility for cloud based computing, but this is also a threat related to security. For cloud users, to maintain their personal data is a major issue related to cloud computing security. Technical security and policies for cloud users plays a vital role in the cloud security. To build trust and establish it for customers who want to use cloud services, is another issue related to the cloud based computing. Security attacks is another issue related

To make the cloud computing be adoptive by users , first to make cloud environment trustworthy to win confidence of users to adopt this technology.
