Questions On Distributed Computing Administrations

Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.

Cloud computing has set a trend in the information technology arena that has sparked the interest of all who utilize the internet on purpose and unsuspectingly. Initially, the primary purpose of cloud computing was to provide a centralized data bank that organizations could use for quick data access. Its use has been quickly adapted, however, beyond business use to become the first option for personal use. The advantages and disadvantages of implementing such a shift from business to personal are varied, yet, statistically, according to the CISCO Global Cloud Index: Forecast and Methodology, 2014-2019 White Paper, its public use is on the rise. The report notes that “by 2019, 56 percent of the cloud workloads will be in public cloud data centers, up from 30 percent in 2014 and by 2019, 44 percent of the cloud workloads will be in private cloud data centers, down from 70 percent in 2014”. Though disadvantages with regard to data security is prominent, users have deemed that its implementation will still promote greater benefits than loss.

This research paper tackles the issues that faces Cloud Computing today and gives the experts and industry’s point of view on the matter. The aspects explored are the significant industry questions that have risen about the use of Cloud Computing, business value, organization impact, adaptability, limitations, initial cost of implementation, and the severe business security risks

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):

Knight capital is cloud based stock exchanging programming. As per New York post, Knight capital on a wrong and a computerized programming which depended on an off base calculation which predominantly costs a firm amazing $440 million in only forty-five minutes. New York post has been depicted it as Meltdown holding up to happen. The program programming which was erroneously has purchased the stocks at the market cost bringing about a few billion dollars of undesirable positions, previously offering the stocks at the offer cost for less cash. This Error has cleared 75 percent of the knight capital's value esteem, which was in the aftermath from the occurrence Knight capital was fined $12 million by the securities and trade commission. In the long run they needed to pitch their business to algorithmic exchanging organization GETCO for a consolidation $3.75/share.

Efficiency— Security concerns limit the benefits of efficiency. The Department of Homeland Security (DHS) highlights security concerns in the cloud computing models (private, public, community, hybrid) as they require continual maintenance, a focus on privacy, and present a lack of complete

Public cloud providers will often have more responsibility for enhancing the security of the data and applications. Within the financial industry data breaches, application vulnerabilities, and availability are all important issues that can lead to legal liabilities.

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

This journal examines the various types of threats that a cloud-based company has to defend against. The authors recognize that the cloud has the potential to be a disruptive force in technology, and it examines the concerns that a business has for migrating to the cloud through the use of surveys. The benefits and risks are examined and the article provides statics and charts to illustrate the findings. The most interesting point of this article is it highlights the concerns customers have listing security as the number one reason preventing a business from migrating to the cloud. I plan to use this article to explain the challenges developers face in securing data on the cloud, not only with application development but also with educating businesses to alleviate misconceptions on cloud computing.

The National Institute of Standards and Technology (NIST) define cloud computing this way. “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics (On-demand self-service, Broad network access, Resource pooling, Rapid elasticity, Measured Service); three service models (Cloud Software as a Service (SaaS),

The reason for the author selecting to look at literature regarding cloud security within this review is because of how it ties in with a Computing Science degree currently being worked towards at Staffordshire University. One of the modules being studied involves the creation of a database system, with the client formally requesting a cloud-based data centre as part of their system. Therefore, it would interesting to take an in-depth look at the security concerns surrounding what is a technology that is still within its infancy stage.

In this paper, the authors survey many sources and literature on cloud security issues, namely vulnerabilities, threats, and attacks. A total of 504 articles were look at to gather the data used in this paper. While the authors use this number to say that the research trend is up on mitigating security risks, they also suggest that security is the main priority of most research to the detriment of other areas. They offer no concrete numbers to back up this claim..

While Cloud administrations offers adaptability, versatility and economies of scale, there have been equivalent worries about security. As more information moves from midway found server capacity to the Cloud, the potential for individual and private information to be traded off will increase. Accessibility and trustworthiness of information are in danger if suitable measures are not put set up preceding selecting a Cloud seller or executing your own cloud and moving to Cloud administrations. Cloud administrations, for example, Software as an administration, Platform as an administration or Infrastructure as an administration, will have their own security worries that need to be tended to. The cloud organizations or the vendors conduct a survey on the issues related to the Cloud security. This paper audits the best practices to secure the cloud administrations and information, the threats associated with the cloud technologies and counting traditional security methods and working with sellers to guarantee legitimate Administration Level Agreements exist.

Cloud computing is vast and so are the security threats. When a company opts for cloud computing, it will consider the advantages, but some of the companies fail to consider the vulnerabilities that might lead to data lost and misuse.

Abstract - Cloud computing is architecture for providing computing service via the internet on demand and pay per user access to a pool of shared resources namely networks, storage, servers, services and applications, without physically acquiring them. So it saves managing cost and time for organizations. Cloud security is becoming a key differentiator and competitive edge between cloud providers.
