Cloud Computing Essay

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of

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 entails the pooling of computing resources from several computers and devices to enhance computing capability and power. These on-demand accesses to required computing resources have enabled organizations to cut down on costs (such as start-up capital and operational costs) significantly through the pay-as-you-use subscription model. Computing resources are provisioned via the internet with minimal management effort from firms providing the service. While this service has greatly improved the operations of organizations, there are several challenges that is has faced. These include: data ownership challenges; data security; data service levels; data privacy protections; data mobility; and high bandwidth costs. Due to the continued growth and expansion of the internet, more organizations are seeking to leverage such technology advancements to enhance their competitive advantage. This paper focuses on cloud security, which forms a vital component for the growth and enhancement of the technology and service provision. It seeks to propose a comprehensive layered framework solution to the security concerns outlined above.

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.

The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

Cloud Computing is a new paradigm of large-scale distributed computing which is rapidly becoming one of the hottest topic among business organisations (Pallis, 2010), and represents a fundamental change in the way of Information Technology (IT) services are invented, developed, deployed, scaled, updated, maintained and paid for (Martson et al, 2011).

Cloud computing depicts the utilization of a gathering of services, applications, data, and framework. While distributed computing is extending quickly and utilized by numerous people and associations globally, clients ' information is generally handled remotely in obscure machines that clients don 't possess or work. Consequently, clients ' apprehension of classified information spillage and loss of security in the cloud turns into a noteworthy boundary to the wide appropriation of cloud administrations. Data Loss/Leakage Prevention has been discovered to be one of the compelling methods for averting Data Loss. In this paper, we will examine about cloud computing data security issues, counting tile security of information transmission, storage, security and administration of security. Concentrate on all inclusive data administration influence cloud security examination, and called attention to that an achievement in the advancement of this cloud computing, attempt to list the comparing

Cloud portability and interoperability varies by authors to authors and researchers. However, there are common aspects in each of the varied definitions, that is, the aspect of cloud service users being able to migrate their service from one platform or service provider to another, with minimal

Cloud computing alludes to a network of computers, connected through internet, sharing the resources given by cloud providers catering to its user’s needs like scalability, usability, resource requirements. The National Institute of Standards and Technology (NIST) gave meaning of cloud computing, which demonstrates the vast majority of the key components of cloud computing [1]: "Cloud computing is a model for enabling convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks,

Cloud computing is currently being used by a large number of organizations. Many consider it a major development of the decade in computing. In this article I define cloud computing, various services available on the cloud infrastructure, then discuss the technological trends which have led to its emergence, its advantages and disadvantages, and the applications which are appropriate to outsource to a cloud computing service.

Many organizations are conveying services from the cloud. Some eminent cases are as per the following:

In this century, Internet is on the edge of another revolution, where resources are globally networked and can be easily shared. Cloud computing is in the focus that uses the Internet as a large repository where resources are available to everyone as services.[5]. many people prefer cloud services for its flexibility,versatility,anywhere accessibility of the services through internet.

Abstract. Cloud computing is the upcoming generation of computation. Internet based computing is known as cloud computing, where software and hardware resources provided to the user on demand. Cloud computing is new paradigm that uses dynamically scalable shared resources e.g. networks, servers, storage, applications and services. It provides different cloud services through which resources can be swiftly providing and released with minimum management efforts. In this paper, we aim to pinpoint the types of cloud, services and difference that shows how effective cloud computing from other paradigm (Grid computing, Utility computing and Mainframe). Last, we will provide an overview on the various challenges and risk associated to cloud computing that deserves future research.

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[NIST].

“Cloud computing” simply means “Internet computing “, generally the internet is seen as collection of clouds; thus the word cloud computing can be defined as utilizing the internet to provide technology enabled services to the people and organizations[1]. Cloud computing is a powerful emerging service that provides an optimized and efficient computing platform by using sharing and virtualization concepts and improving availability, scalability, collaboration and agility for users and enterprises [2]. Cloud computing has a rapid growth in IT industries due to the considerable benefits of sorting and maintaining resources in unlimited storages with the most cost efficient method, business continuity and scalability [3]. However, the only hurdle in wide adoption of this newfound technology is lack of security especially in data protection, authentication, and data transmission subject [4].
