Abstract-- Cloud computing is a new paradigm that combines several computing concepts and technologies of the Internet creating a platform for more agile and cost-effective business applications and IT infrastructure. The adoption of Cloud computing has been increasing for some time and the maturity of the market is steadily growing. Security is the question most consistently raised as consumers look to move their data and applications to the cloud. I justify the importance and motivation of security in the migration of legacy systems and I carry out an approach related to security in migration processes to cloud with the aim of finding the needs, concerns, requirements, aspects, opportunities and benefits of security in the migration process of legacy systems.

BACKGROUND

Overview of Cloud Computing

Cloud computing services such as Amazon EC2 and Windows Azure are becoming more and more popular but it seems many people are still unclear as to what exactly the buzzword “Cloud computing” actually means. In its simplest form, the principle of
Cloud computing is the provision of computing resources via a network.
Cloud Computing has become one of the most talked about technologies in recent times and has got lots of attention from media as well as analysts because of the opportunities it is offering. The market research and analysis firm IDC suggests that the market for Cloud Computing services was ` 68000 crore in 2008 and will rise to `178500 crore/year by 2012 [1]. It has been estimated that the cost advantages of Cloud Computing to be three to five times for business applications and more than five times for

    With the unprecedented growth and spread of information, there is no wonder why large Information Technology companies have been investing in the “cloud”. To expand, when referring to Cloud Computing, this means to access and store information not stored with in your computer whether it be public, private, or hybrid cloud computing. In technological terms, the server you are accessing is somewhere else and therefore, the information and tools you are using are “up in the clouds” but more so stored in another server space. However, whether you are paying for services through software, total usage, or free usage (hence the types of cloud services) Cloud Computing seems to be everywhere. Yet, it is important to recognize what is to gain by using cloud computing from big businesses to individual users and what are some risky moves when utilizing cloud storage over the Internet.

    Cis 500- Cloud Computing

    Technology has taken great leaps of advancement. Some of the new technology that companies and consumers are taking advantage of to store and process data is cloud computing. Cloud computing was derived from virtualization. Virtualization allows companies to separate business applications from hardware. Doing this gives the company the capability of assigning applications as needed. The option to manage applications is a great benefit to companies. Resulting from the virtualization error, cloud computing has emerged to provide flexible IT infrastructures. This has not only enhanced the options companies now have, but it is also proven to be more cost efficient. This has increasingly become a preferred method of companies and consumers alike.

    Sea Imagery in Charles Dickens’s a Tale of Two Cities

    In Charles Dickens’s Book A Tale of Two Cities, he illustrates the French Revolution and its effect on the people. Through the stories of revolutionaries, upper-class, and lower-class citizens he creates a dichotomy between Paris, France, and London, England, to caution England about what will happen if their government continues to run as France’s does. Dickens uses imagery of the sea to warn that a hellacious government leads to an equally hellacious revolt.…

    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 companies or individuals who couldn’t able to buy costly software or any other resources. This becomes easy because of cloud computing. Cloud promises real costs savings and agility to customers. It’s a ‘Pay for Usage’ plan. We pay the money based on our usage only. Through cloud computing, a company can rapidly deploy applications where the underlying technology components.

    Business Value of Cloud Computing

    Cloud computing offers software and hardware resources and in some cases human services over a distributed environment that can be shared and utilized on demand through internet. Business owners can use these resources as per their requirement even if that is for few hours a day or few days a month and have to pay only for that actual use. Thus this relatively new concept is becoming highly popular among IT organizations because of its flexibility and cost effectiveness. It is highly scalable and also can span quickly according to the requirements of individual organization yet still sharing the same resources.…

    Inf 103: Computer Literacy

    The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “a model for enabling ubiquitous, 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”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology services over the internet to many users in an on-demand environment (P.Y. Thomas 2011). As you can see by the definitions above the term Cloud Computing has been defined, yet many of us are barely getting to understand how this type of computing affects the work we do both in our personal life and in the workplace. In the following pages you will see how cloud computing is the way of the future without it being limited to business applications; furthermore creating a niche in the social media/personal computing we do on a daily basis.…

    I got the chance to observe a couple of invasive Cath-lab procedures on February 23, 2016. I was extremely nervous upon arrival, primarily because I wasn’t quite sure what to expect mentally. Immediately at 0630, invasive cardiac unit has a quick huddle for important announcements and a brief explanation for the procedures for this specific day. They made an announcement about having twenty scheduled procedures for the day and that it was going to be a slow a day; since they typically schedule around fifty a day. After this five-minute huddle everyone went to start their day.…

    Cyber Security

    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 due to centralization of resources. Brian Proffitt will argue in is IT World article [24], there are some serious limitations with cloud computing that is being blithely ignored such as bandwidth limitation, storage, and availability. Interviews conducted with colleagues that are experts in the Enterprise Systems network arena reveals that, the impact is all in planning before implementation, the selected architecture and the security policy. Findings in manuscripts and online libraries reflect that Cloud Computing is a technological revolution that provides computer resources as a service; offering flexible IT usage, computing efficiency through improved utilization and reduced administration and infrastructure costs. Users are not limited to applications confined to a computer, data stored to a hard drive, or bounded by the organization’s network. Also known as the sum of Software as a Service (SaaS) and Utility Computing, Cloud Computing is argued to be more efficient and scalable. My hope is to identify the common issues that face Cloud Computing in organizations that have implemented it, and find the answer or probable solutions.…
