Cloud Computing Case Study

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

User can store their data on cloud and reveal from the local data storage and its maintenance. Cloud is in a distributive in nature includes shared pool of configuring resources both in hardware and software. As an increasing number of clients who store their

Cloud computing can be viewed as one of the most rapidly growing and evolving paradigm.Webmail,online storage and online documents are most famous examples in which customers can access their data via web browsers on the internet. The original idea of the cloud computing was delivered by J.C.R Licklider in sixties (Mohamed 2009). Cloud computing has developed since then and started to server the publics after internet offered a significant bandwidth in the nineties (Mohamed 2009). Cloud computing has been through many different phases and is still rapidly evolving.

Cloud computing combines a number of computing concepts and technologies in objective to provide secure, quick, convenient data storage and net computing service with all computing resources visualized as services and delivered over the internet. Cloud computing has brought financial benefits and promises to many business and organizations a way to enhance their information technology such as collaboration, agility, scalability and availability without heavy upfront capital costs in servers meanwhile achieving minimal management effort for service providers.

Cloud Computing provide enterprises and users with varieties of capabilities for store and process data in the data centers of third-party. It depends on resources sharing to carry out accordance and economies of scale, like a utility over a network. The basic of Cloud Computing is the extended concept of sharing services and aggregate infrastructure. It is the product of evolution and using current exponents and technologies.

Cloud computing is a set of Information technology services that are given to a client over a network on a leased basis and with the capacity to scale up or down their administration prerequisites. Typically distributed computing organizations are passed on by an outcast supplier who claims the structure. It central focuses to say however several fuse flexibility, quality, versatility, adequacy and outsourcing non-focus works out. Distributed computing offers an innovative arrangement of activity for relationship to get IT advantages without blunt endeavor. Despite the potential augmentations achieved from the distributed computing, the affiliations are subsiding in enduring it due to security issues and challenges joined with it.

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

IT departments and infrastructure providers are under increasing pressure to provide computing infrastructure at the lowest possible cost. In order to do this, the concepts of resource pooling, virtualization, dynamic provisioning, utility and commodity computing must be leveraged to create a public or private cloud that meets these needs. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. This provides the smaller

At this stage, the company should begin pondering whether it needs to make diverse IAM groups for various business functions inside the organization or make groups for various IT roles (administrators, designers, testers and so on) and whether it needs to make clients to coordinate the organization chart or make clients for every application.

In cloud computing, to protect data from leaking, users need to encrypt their data before being shared. Access control [6], [7] is paramount as it is the first line of defense that prevents unauthorized access to the shared data. With the burgeoning of network technology and mobile terminal, online data sharing has become a new “pet”, such as Facebook, MySpace, and Badoo. Meanwhile, cloud is one of the most promising application platforms to solve the explosive expanding of data sharing. In cloud computing, to protect data from leaking, users need to encrypt their data before being shared. Access control is paramount that prevents unauthorized access to the shared data. Recently, attribute-based encryption (ABE) has been attracted

Going to the Cloud is like switching off your electricity generator and moving to the power grid. Cloud mobility and the Internet of Things (IoT) has provided businesses with greater flexibility in the services they offer and the improvement of processes behind those offerings. With the driving of Cloud based applications, primarily motivated by the benefits of the fast on-demand availability of big tech cloud providers such as Amazon AWS, Google Cloud and Microsoft Azure – new types of services are beginning to replace functions that were traditionally done in-house.

Cloud storage service has become a new profit growth point by providing a low-cost, scalable, location-independent platform for managing clients’ data. The data security is critical and the customers trust that the information is safe in the storage, because the cloud infrastructures are powerful than regular personal computer devices. Data integrity verification is one of the most basic and critical techniques in outsourced cloud storage. The reason for the existence of private cloud is that it offers the greatest level of security and control for enterprises’ sensitive data, hence security risks are less as compared to those stored

• Confidentiality – this process also known as privacy process. It is a process of making sure all the data is secure and encrypted while the data is on moving over the entire system network. With this process, the data may remain the state of private and confidential, it is also avoid unauthorized user (which include the network administrator whose task are monitoring the network traffic) from getting the data.

Cloud computing is an ideas that information in addition programs that may be stowed centrally, in the cloud, as well as gain access to some extent time as of anyplace by means of reedy users plus portable devices. This system lead too many benefits, containing with information ubiquity and give of access (Ryan, 2013). Cloud computing also might improve security, which might be able to invest in more informed technologies in addition training. But, meanwhile cloud computing essentially places information or data separate of the control for the data proprietor, the situation presents challenges as well.

When you store your photographs online rather than on your home machine, or utilization webmail or an interpersonal interaction webpage, you are utilizing a "distributed computing" administration. In the event that you are an association, and you need to use, for instance, a web invoicing administration as opposed to redesigning the in-house one you have been utilizing for a long time, that web invoicing administration is a "distributed computing" administration. Distributed computing alludes to the conveyance of processing assets over the Web. As opposed to keeping information all alone hard drive or overhauling applications for your needs, you utilize an administration over the Web, at an alternate area, to store your data or utilize its applications. Doing so may offer climb to certain protection suggestions. Thus the Workplace of the Security Official of Canada (OPC) has arranged a few reactions to Every now and again Made inquiries (Faqs). We have additionally created a Truth Sheet that gives data on distributed computing and the protection moves it displays. [1]
