The Importance Of Cloud Computing

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 offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

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 computing is revolutionizing many ecosystems by providing organizations with computing resources featuring easy deployment, connectivity, configuration, automation and scalability. This paradigm shift raises a broad range of security and privacy issues that must be taken into consideration. Loss of control, and trust are key challenges in cloud computing environments. This paper will be describing and focusing on cloud security and privacy. In addition to cloud security, the general model of cloud computing is also described where the cloud security and privacy issues can be approached. To preserve such issues, some propositions for cloud security for reference are also proposed along with a brief description for deployment in cloud computing.

Cloud computing is a one of the most talked of topics in the field of Information Technology in recent times (Keyun, Joe, Taha, & Ibrahim, 2013). This subject area of cloud computing basically is a term used to describe computer resources available as a service accessible over a network (Darren & Kim-Kwang, 2013). The National Institute of Standards and Technology (NIST) define cloud computing as a model for enabling ubiquitous, convenient, on-demand network access on 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 (Peter & Timothy, 2011). Due to the attractive nature of the model there has been rise in the use of cloud computing. Gartner, an IT research and consulting firm, says that cloud computing is growing will become the bulk of IT spend by 2016 (Gartner, 2013).

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

Cloud computing security is a set of control based technologies and policies that must follow certain rules in order to protect applications, data and any information associated with cloud computing. It is known to provide excellent services but is still not supported by organizations due to privacy issues that includes security and privacy protection. As they obstruct the managers as well as the

Abstract—The field of cloud computing has grown in popularity over the years with big software giants like Amazon, Microsoft and Google providing their own offerings. Some of features which make the cloud so attractive is the fact that it provides rapid elastically and easy scalability. Even though cloud adoption has been quite rapid, many of the business are reluctant to move to the cloud owing to the security and privacy concerns associated with the cloud. In this survey paper, we explore some of the security issues in cloud computing and the current efforts of the research community to tackle these issues.

The development of cloud computing services is speeding up the rate in which the organizations outsource their computational services or sell their idle computational resources. Even though migrating to the cloud remains a tempting trend from a financial perspective, there are several other aspects that must be taken into account by companies before they decide to do so. One of the most important aspect refers to security: while some cloud computing security issues are inherited from the solutions adopted to create such services, many new security questions that are particular to these solutions also arise, including those related to how the services are organized and which kind of service/data can be placed in the cloud. Aiming to give a better understanding of this complex scenario, in this article we identify and classify the main security concerns and solutions in cloud computing, and propose a taxonomy of security in cloud computing, giving an overview of the current status of security in this emerging technology.

IT departments are controlled by market-driven demands from employers to provide data that is current and up-to-date for businesses to operate effectively in today’s market. Thus, the demand and delivery of current technology are the main focus for IT department infrastructures. IT infrastructures include systems, software and application platforms, data assets, and related business processes and practices. Coupled with the understanding of the IT infrastructure is the need to deliver the data to the business environment which can be provided by different means of cloud computing. At the present time, cloud computing is a platform which allows people to connect to information anywhere at any time. The cloud, in reality, is the internet. This internet based platform allows companies a way to access computer resources as utilities. Cloud computing can be dissected into a few categories, infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service

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 has become a compelling paradigm for delivering and managing services over the internet. Although it might be difficult to define cloud computing, one simple definition of the term is virtualized third-party hosting. In simple terms, instead of renting the entire or actual physical server, one rents a certain proportion of server resources. The client’s server runs within a virtual container that may be moved from a physical server to another without service interruption. Cloud computing has changed the entire landscape of Information Technology, and it is finally actualizing the long-standing promise of utility computing. This paper serves as a comprehensive overview of the cloud computing technology; definition,

Cloud computing is a technology trend which is enabling and driving new markets in technology. Cloud computing refers to the idea of delivering personal (email, word processing, presentations, etc.) and business productivity applications (sales force automation, customer service, accounting, etc.) from centralized servers that share resources like storage, processing and bandwidth more efficiently by a cost factor of at least 5-10x. Cloud computing continues to garner a lot of industry buzz, but currently security and the cloud mix about as well as oil and water. There are many security challenges that enterprises face as they evaluate the agility, economics, and

The most important and readily accessed change is introducing a cloud-based system in the organization with a remote server of the software. Cloud-based systems offer great and improved flexibility. These systems can be upgraded on a continual basis, and it separates the IT system from its hardware platform and significantly reduces the capital cost of the IT infrastructure. Globally, the pharmaceutical companies are using Business Planning and Control System (BPCS) as their ERP software designed for an OS/400 system. BPCS is a software program that is the largest software supplier for AS/400, an ERP system. Global supply chain organizations are moving towards implementing another system called Systems Applications & Products

We assume that the public cloud infrastructure provides proper security and data backup solutions with a Service Level Agreement (SLA) and mechanisms to fairly share its virtual resources among all its running VMs. The last few years have witnessed the emergence of cloud computing as a rapid, limitlessly scalable, and cost-efficient alternative in contrast to the in-house data centers. The IaaS model delegates more control to the customers over the provisioned resources. Hosting Internet applications in the IaaS environment is an efficient way to start a new and a sustainable business that expands the IT infrastructure gradually with the business growth.
