What Is Cloud Computing?

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.

As I mentioned above, cloud computing is relatively new, and like any other new technology, it brings with it exposure and risks. As more and more data is migrated online, concerns are beginning to grow about just how safe it is. Indeed, because every component in Cloud computing is potentially accessible from the Internet, security in the Cloud

However, with all the benefits, the rapid development of information and communication technology (ICT) involves certain security challenges as well. The associated challenges and issues of Cloud computing must be considered prior to the ubiquitous adoption of the technology [2]. The paper presents the analysis of the cloud computing model in terms of the deployment of its service models, along with the security issues associated with it. The paper also presents the possible techniques of eliminating the security concerns of the cloud computing.

HOW FUTURE IT TRENDS WOULD IMPACT ORGANIZATIONS BUSINESS STRATEGIES TO DRIVE INNOVATIONS, ADD VALUE AND GAIN COMPETITIVE EDGE?

ABSTRACT: Cloud computing is nothing but an internet based connection to remote servers which allows to store data and access to all services. These services are provided by the third party who owns the infrastructure. Cloud computing is classified into public, private or hybrid. It is a kind of grid computing. It is flexible and easy to adapt. Apart from advantages organizations are very slow in processing the customer resources because it has some security issues and challenges associated with it. Security is the main issue which is becoming a big hurdle for the growth of cloud computing. The companies are worrying to handle some important data to other companies due to these security challenges. This paper is going to give brief

Reaching the point where computing functions as a utility has great potential, promising innovations we cannot yet imagine. Customers are both excited and nervous at the prospects of Cloud Computing. They are excited by the opportunities to reduce capital costs. They are excited for a chance to divest themselves of infrastructure management, and focus on core competencies. Most of all, they are excited by the agility offered by the on-demand provisioning of computing and the ability to align information technology with business strategies and needs more readily. However, customers are also very concerned about the risks of Cloud Computing if not properly secured, and the loss of direct control over systems for which they are nonetheless accountable. To aid both cloud customers and cloud providers, CSA developed “Security Guidance for Critical Areas in Cloud Computing”, initially released in April 2009, and revised in December 2009. This guidance has quickly become the industry standard catalogue of best

People are utilizing cloud computing without having knowledge of it. Cloud computing is getting sophisticated with each passing day. Cloud computing is described by various organizations and IT professionals in different words. According to Almadallah,M, (2014, p.1) there is a fundamental program over the Internet, which is easily accessible to everyone, and gives an approach to users to progressing data, using services, running applications and updating software whenever and wherever they need.. This is known as “cloud computing.” Data with range and trustworthiness is being delivered over the Internet by cloud computing. According to Rajaraman,v(2014, p.242).People usecloud services as operating systems that run on personal computer and administered by special software. For example, Gmail, Yahoo mail, and Hotmail are provided by Google, yahoo and Microsoft and are used to send e-mail.

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)

The effects of these dangers can go from information spillage to identity fraud. Information protection and security, outside dangers, visitor to-cloud dangers, other security issues are likewise getting to be vital in Cloud Computing. As expanded measures of information are transmitted over the web and pernicious conduct proceeds with, the assurance and safeguard of information inside the cloud will dependably be display.

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,

From the previous section, we see a very wide range of services provided by cloud technology. The main idea of cloud is dealing with connection from internet and make internet as its “computer-based”. Therefore, maintaining security in the cloud is like safeguarding the jungle because every weakness in network link are adversary’s opportunity to harm our properties. Security concerns in cloud services could be related to Integrity, for instances users who use PaaS will not let anyone influence or change his application code. Another concern is confidentiality

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 ,

Whenever an examination about cloud security is occurred there will be particularly to accomplish for it. The cloud service provider for cloud ensures that the client does not confront any issue, for example, loss of information or data theft. Likewise, there is a probability where a harmful user can infiltrate the cloud by claiming a authorized user, there by infecting the whole cloud. This prompts to influences numerous clients who are sharing the contaminated cloud. There are four sorts of issues raise while examining security of a cloud.

In the information technology world Cloud computing is the latest development. By offering the services on demand it was revolutionized the digital world. On the client side there is no need to maintain the infrastructure and also there are many advantages of this cloud computing technology and this research paper will discuss all the things like the developments and trends and latest technologies used in this field.

In certain cases, data is stored permanently. Nearly 164 Sun enterprise class servers are used in DAS architecture. The total capacity is of several TB’s. The Sun hardware uses an in-built storage management tool. Later look over a storage management application from VERITAS.
