Cloud Computing : A Modern Day Technological Innovation

The cloud can provide swift access to malleable and low budget IT resources. With the use of cloud computing, you are not required to make big direct investments in hardware and spend a lot of time on managing that hardware and associated services. Cloud Computing compromises a comprehensive set of on-demand services, such as global computing, storage, database, analytics, application, and deployment services. These services will assist an organization move quicker, reduce IT costs, and scale systems. Cloud Computing has three key categories, they are usually referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Mobile as a Service (MaaS) and Software as a Service (SaaS).

However, research focusing on the adoption of cloud computing technology and its impact on business operation is limited. This trend may be explained by cloud computing being a relatively new field. Available research on the structures, processes, security measures surrounding the cloud services are still at an early stage.

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

The “cloud” provides rapid access to flexible and low cost IT resources; people can access as many resources as the need, almost instantly, and only pay for what they use. There are six advantages and benefits that AWS is advertising, such as pay for how much you consume; achieve higher economies of scale which translates into lower pay as you go prices; eliminate guessing on your infrastructure capacity needs; increase speed and agility; stop spending money on running and maintaining data centers; and provide lower latency and better experience for your customers simply and at minimal cost. Cloud computing has three main types that are commonly referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS contains the basic building blocks for cloud IT and typically provide access to networking features, computers, and data storage space. Also, it provides with the highest level of flexibility, and management control over your IT resources and is most similar to existing IT resources that many IT departments and developers are familiar with today. PaaS remove the need for organizations to manage the underlying infrastructure and allow you to focus on the deployment and management of your applications; this helps to be more efficient and not to worry about resource procurement, capacity planning, software

According to Lawrence Shawa, "a number of organizations I have spoken to have expressed concern about how secure their data is that is hosted in the cloud. There is sense of control that is taken from them making the organizations feel vulnerable" (Collection 2:1) Companies naturally feel a strong sense of obligation to protect their customers. Additionally, they may lose business if they have a reputation for compromising customer security.

When deciding which information, the company wants to move to cloud, the division of responsibilities needs to be clear between providers and customers, and an analysis of their security roles depending on the type of service offered (Software, Platform, or Infrastructure) (Gonzalez, et al, 2012). Prior to the start of the service contract, the security roles and responsibilities for everything needs to be clearly acknowledged. The management, cost, and security of clouds depend on whether an organization chooses to buy and operate its own cloud or to obtain cloud services from a third party (Grossman, 2009). Each of these choices has its own security and privacy issues. Some security concerns are lessened when a private cloud is used. Only your own information is stored there and the benefits of security might outweigh the costs. Two of the disadvantages of using a private cloud is the level of knowledge needed to support the cloud and the frequency of maintenance. On the other

Cloud computing is a relatively new technology that allows data to be stored, distributed and manipulated with greater ease than ever. As described by Gurjar and Rathore (2013), the “Cloud is a large pool of easily usable and accessible virtualized resources. These resources can be dynamically reconfigured to adjust to a variable load, allowing also for an optimum resource utilization” (p. 1). By moving data, documents and media to the Cloud, the potential for business efficiency and productivity increases and anyone with internet can take advantage of the benefits. As with anything, it is important to understand the risks and benefits in order to weigh whether or not moving to the Cloud is the best move for the business. Some companies,

The use of cloud computing creates a growing interdependence among both public and private sector entities and the individuals served by these entities. This paper provides a snapshot of the advantages of cloud computing and the risk areas specific to cloud services which clients of cloud services should be aware of. The future of cloud computing is certainly exciting, but moving more of our lives online means we will inevitably have to consider the consequences. Cloud computing means dependence on others and that could limit our privacy because

Cloud computing has become a major topic of discussion and debate for any business or organization which relies on technology. Anyone connected to the Internet is probably using some type of cloud computing on a regular basis. Whether they are using Google’s Gmail, organizing photos on an Apple iPhone’s photo steam or searching the Web with Bing they are engaged in cloud computing. The interesting thing about cloud computing is it did not start as a technology for the business enterprise, but was driven by the public with services like Facebook. Over the last few years businesses have started to see the value of cloud computing causing it to become a major technology solution for businesses and organizations around the world.

The Cloud Computing refers to “Computing over the Internet”.It came from Grid,utility and web services.It is a combination of network,servers,storage ,operating system and virtualization technologies to form a shared infrastructure that enables web-based value added services.End users access cloud-based applications through a web browser or a light-weight desktop or mobile application.The business software and user 's data are stored on servers at a remote location. The cloud model comprises five

In fourth section, the article discusses cloud offering under three types of service models. These are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). IaaS provides fundamental computing resources (storage, network, processing) as a service where subscribers are able to deploy and run their choice of operating system and software applications. PaaS is the next level of service, where subscribers have an operating system in addition to hardware as a service, and have control over changes in the application and hosting environment. SaaS is the third level of service, in which client get software also as a service in addition to an underlying operating system and hardware. All the services offers pay-as-you-use.

Cloud computing has now become a competitor to traditional IT because of how cheap it is and that it is based on “pay-as-you-go” service just like electricity or gas. There has been a great increase in the migration of businesses into cloud. Cloud has its down side but the advantages are higher and almost negate the downsides. Some of these advantages are resource availability on demand, pay as you go, hardware utilization is better and more efficient, no in house losses with respect to hardware and since there is no hardware involved the maintenance is low too. Cloud computing is drawn-out from distributed computing,

A cloud is a unique information technology (IT) environment which has been designed for the purpose of provisioning, scalable and measured information technology resources remotely. Cloud Computing Service provides IT as a service over the internet on demand basis and the payment is based on usage. Cloud computing services are provided from development platforms and full applications to servers and storage. Cloud computing is a pervasive advancement which gives a beneficiary way to the clients to benefit the cloud applications on interest. It refers to the network service in which services are provided with assured QoS, affordable computing infrastructures with an easy and simple access on demand and is enabled

Cloud computing have revolutionized life as we know it; it allows people to store, manage, and access their data by using a network of remote servers which are hosted on the internet rather than using a local server or own hardware. A recent study conducted by KPMG found that 81% of businesses were either evaluating cloud services, planned a cloud implementation or had already implemented a cloud strategy [1]. Organizations tend to use the cloud to reduce costs and improve efficiency. Cloud is not a commodity, some people think that it comes out of the sky, while in fact it comes from physical hardware inside brick and mortar facilities which are connected to hundreds of miles by networking cables.

Over the years, computing concepts changing from distributed to parallel to grid to cloud computing. The evolution of computing is shown in Figure 1. Now a day, people choose cloud computing because of the advantages they get from cloud computing. The advantages are scalability, reduced management efforts, on-demand resource allocation and flexible pricing model (pay-as-you-go). Cloud computing has three service models: Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS). The basic concept of cloud computing and services is shown in Figure 2. Example of application or services using cloud computing are Microsoft OfficeLive, Dropbox, CluodNumbers, Google AppEngine, SalesForce
