Case Study Of The Performance And Security Challenges In Cloud Computing

The cloud can provide swift access to malleable and low budget IT resources. With the use of cloud computing, you are not required to make big direct investments in hardware and spend a lot of time on managing that hardware and associated services. Cloud Computing compromises a comprehensive set of on-demand services, such as global computing, storage, database, analytics, application, and deployment services. These services will assist an organization move quicker, reduce IT costs, and scale systems. Cloud Computing has three key categories, they are usually referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Mobile as a Service (MaaS) and Software as a Service (SaaS).

Cloud computing offers many advantages to both end users and businesses of all sizes. The advantages of cloud

We would like to provide the benefits of cloud computing without any troubles to propel in the direction it is designed for. This is to be achieved by preventing the owner's data from all risks associated and providing a cloud model that is more secure and efficient. The proposed model shall overcome the security risks defined by the security functions over cloud computing, as follows in (Passent M. et al., 2015):

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.

A significant paradigm shift is represented by public cloud computing from conventional norms of an organizational data center to a de-parameterized infrastructure which opens gates for potential adversaries to use. Cloud computing should be approached carefully with any emerging information technology area with due consideration to the sensitivity of data. A good planning helps and ensures that the computing environment is secure to the most possible extant and is in compliance with all relevant policies of an organization and makes sure the privacy is maintained.

DATA SECURITY IN CLOUD COMPUTING Introduction: Cloud computing has prompted a movement in how individuals consider IT frameworks structural engineering. Numerous associations today are either executing cloud-based services, or assessing which cloud-based measures they will be portraying later on. As indicated by Gartner Inc. distributed computing is "no less compelling than e-business". This sprocess in building design from an undertaking normal server-based framework to a cloud-based framework will have related expenses of passage and dangers, yet it can bring about inconceivable advantages in reserve funds and in IT and business deftness.

Cloud computing has formed the basis for future computing. The global computing infrastructure is rapidly moving towards cloud computing. While it is important to take advantages of it by means of deploying it in diversified sectors, the security aspects in a cloud based computing environment should be considered (Ahmed, 2014). Cloud computing is still a new technology in many enterprises. Findings show that most organizations are reluctant to adopt it and the demand to reduce computing cost has led to this great innovation (Agarwal, 2012). A sample size of 150 technical IT people will be used for data collection through questionnaires and interviews and the data collected will be analyzed using SPSS. The purpose of this study is to identify the cloud computing concepts as well as security issues inherent within cloud infrastructure. The adoption of cloud computing is not as complex as many organizations have thought and by moving the applications and hardware out of the organization the user can focus on its core strategies.

Cloud computing is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure. [1] Example: Google application engine, Software as a Service (SaaS) is

Security is additionally one of the significant worries of the cloud computing innovation and is evident through the prior investigations. There exist a few dangers included which will limit the organizations in partaking and actualizing these cool administrations. There exist significant odds of dangers like losing of information, information ruptures, in security to the secret information which can affect the organizations. In this manner, the vast majority of the organizations introduce in the market fears to render their private information helpless against the uncertainties of unapproved access and they were in that by embracing the cloud benefits, their information might be more presented to dangers and likely of getting assaulted or

Abstract - Cloud Computing is huge computing, it is the internet based computing, where all users can remotely store their data into the cloud so as to enjoy the latest and high quality applications and services. In outsourcing data , users can be relieved from the burden of local maintenance and data storage .Thus, enabling public auditability for cloud data storage security is of difficult so that users can resort to an external audit party to check the integrity of outsourced data when needed. To securely introduce an effective. The following two fundamental requirements to securely introduce an effective third party auditor (TPA) .1) The third party auditing process should bring in no new vulnerabilities towards user data privacy. 2) TPA introduces no additional on-line burden to the cloud user. TPA should be able to efficiently audit the cloud data storage. 3) TPA should audit the data for checking the integrity of that data. In this we propose for privacy-preserving public auditing for cloud data storage.To enable the TPA to perform audits for multiple users simultaneously and efficiently.We also doing batch auditing for multiple users data.

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)

There would various security issues to cloud computing Concerning illustration it includes Numerous innovations including networks, databases, operating systems, virtualization, asset scheduling, transaction management, load balancing, concurrency control and memory administration. Therefore, security issues to a significant number of these frameworks and innovations would relevant to cloud computing. For example, those system that interconnects the frameworks to a cloud need to be secure. Furthermore, virtualization standard clinched

Cloud Computing appears as a computational paradigm as well as distribution architecture and its main objective is to Provide secure, quick, convenient data storage and net computing device, with all computing resource visu-alized as service ,with all computing resources visualized as service and delivery over the internet [1,2].The cloud enhances collaboration, agility, scalability, availability, ability to adapt to fluctuations according to demand, accelerate development work, and provides potential for cost reduction through optimized and efficient compu-ting [3,5].Cloud computing is buzz word of IT industry today and present everywhere and every one's mind. Cloud computing is ubiquitous, next generation's infor-mation technology architecture which offers on-demand access to the network. It is dynamic, virtualized, scalable and pay per use model over internet. Cloud computing is a box of several concepts such as virtualization, Service oriented architecture (SOA), web 2.0 and many more. In some respects, Cloud Computing represents the maturing of these technologies and is a marketing term to repre-sent that maturity and the services they provide [4].There are several advantages of adopting cloud computing but still journey of cloud is not easy. Cloud still is its early stage, suffering from many pitfalls and one of the most concern is security along with availability, privacy and compliance. Traditional security mechanism such as Authentication , authorization ,

Delicate information in a cloud computing environment rise as real issues concerning security in a cloud based framework. If an information is on a cloud, anybody from anyplace whenever can get to information from the cloud since information might be common, private and sensitive data in a cloud. So in the meantime, many cloud computing service consumer and supplier gets to and adjust information. In this way, there is a need of a integrity of data in cloud computing. Also, information stealing

Abstract:Cloud computing is a paradigm in which services (Iaas,Paas,Saas) are rented to the user as per demand.But data security is main issue when we are using public cloud service provider.whether the confidential data kept on the central storage on cloud is secure?
