Cloud computing can be described as a platform as well as an application. When it comes to platform it enables supply, configuration, and also the reconfiguration part, on the other hand, servers can be in the form of machines or virtual machines. It also describes the applications that are extended so that access can be done through the help of the internet; and hence for this reason huge data centers and potent servers are taken help to host the web application, and other useful services. It can also be said to be a metaphor for the Internet and in the description some points are to be taken care of (Armbrust & Fox, 2010).
In the enterprise, making use of the Cloud Computing is the maximum amount captivated with the maturity of structure. There are several utilities declared of Cloud Computed by completely different researchers that create it additionally preferred and hence adopted by enterprises. Cloud computing structure permits to realize additional economical use of their IT hardware and software package investments (Durkee, 2010). Hence it is the best technological improvement, which promotes efficiency as well as aimed towards boosting the performance.
The current market for Cloud computing:
Cloud computing is the need of the hour and popular everywhere because this technology is one of those which has created a lot of opportunities and has attracted immense attention. According to IDC, which is a market research and analysis which has suggested that the market for cloud computing services, was 16$ billion in the year 2008 and will enhance to 42$ billion per year by the year 2012 (Chee & Curtis Franklin, 2009). As per the estimation the cost advantages of Cloud Computing are around three to five times to the applicatio...

Today, cloud services are widely used by people around the world in purpose of business, government, and personal use. With cloud services, users use resources - could be storage, computional capability, or software- from cloud service provider mediated by Internet. Doing computational work with cloud services involves a number of computers to do the large-scale works, therefore it usually called by distributed system over Internet (reference, paper?). Cloud service also offers a large-scale service where users only pay for what they use (on-demand). Therefore, companies migrate to business-to-business cloud as they don’t have to spend money building intial cost for their computational business. For instance, instead of building their own storage, network, cooling, they could just “rent” resource from cloud provider for the lower cost. Besides money benefits, cloud resources also able to be shared by multiple...
With the booming of cloud, a increasing number of enterprises are considering transferring the business to cloud because the move seems to help the enterprises not only to enhance working efficiency but also to decrease operating cost. However, findings indicate that under current circumstance, the portability of enterprises based on cloud is limited (Armbrust et al., 2010). Comparing to the potential expenditure one enterprise may face, the benefits it gains from may appears less attractive. Evidences in aspect of costing, efficiency and security are showed and discussed to get a conclusion.
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. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
To understand how cloud computing can be of value to an organization, it is important to us that we understand the cloud and its components. There are three different types of cloud computing services referred to as Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). IaaS delivers cloud computing infrastructure servers, storage, network and operating systems as an on-demand service. SaaS is about software deploying over the Internet. PaaS allows a creation of web applications without the complexity of buying and maintaining the software and infrastructure. In this paper, I will suggest that Innovartus Technology Inc should use IaaS as a replacement for PaaS because IaaS is a rapidly developing field with resources such as better services, cost variability, utility pricing model and dynamic scaling.

Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access

Cloud computing is being heralded as the onrushing future of computing. In fact, in many ways, cloud computing is already here, and has been for some time. The most obvious example of cloud computing is Google Mail. Cloud computing, simply defined, is the implementation of computing services using shared hardware, shared software and in many cases even shared information. Google Mail, for example, makes e-mail services available using a widespread, highly redundant network of systems that remove that same functionality and data from the user’s computer, putting it “in the cloud” where it can be plucked back out as needed – from any capable device such as a smart phone, computer or internet kiosk.

When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.
Cloud computing is the progression of other computing technologies such as paral-lel computing, distributed computing, and grid computing. Its main principle is to disseminate the computing grind stones to distributed computers. Majority of us still use the PC’s and laptops to cache the data and files, sharing of data and files, and to send emails. If our pc’s diverse...
Cloud computing is a model for delivering data resources to cloud end users, in which data resources are stored in distributed manner, data resources can be accessed on the internet using web-based tools and applications. Data and software packages are stored in server database. However, cloud server allows the cloud users to access data resources as long as system is connected to the internet.
Cloud computing is one of the fast growing trend in today’s world. Each day there will be new updates to be popped out about cloud computing. Cloud computing is a type of computing that relies on sharing computer resources rather than having local servers or personal devices to handle application. Cloud helps us to access the software that we have in our pc. Cloud computing is always user-centric, task-centric, powerful, accessible, intelligent, programmable. Users connect to cloud from their personal computers over internet where the user can see only the application they use but not the cloud hardware and its operating system. SAAS, PAAS, IAAS are the cloud service. SAAS is defined as service-on-demand, where a provider will license software tailored. In PAAS model, cloud providers deliver a computing platform. IAAS model provides computers physical or virtual machines and other resources. Cloud storage is nothing but the storage of data online in cloud, where the storage is of three types- public, private and hybrid cloud. Finally we have overcome the drawback of the data loss due to server crash via duplication of data in more than one server.
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
