Cloud Computing Is Becoming The Most Popular Topic

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

There are three standard service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). IaaS is when the cloud

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,

Cloud computing has grown in popularity to the point that it is now becoming the preferred method of the business community for accessing services on the Internet. This paper examines the reasons for this growth and explores the benefits and drawbacks of this technology.

The advantages of cloud computing include cost savings, meeting computing needs, reliability, and centralized security functions. This will lead to overall lower costs, improved information handling, and greater convenience for end users. All of these advantages make cloud computing worth considering.

Despite these advantages, cloud computing carries with it some inherent risks that need to be evaluated before a firm makes the decision to adopt this computing model. In order to eschew the in-house data center and IT department for a cloud-based solution, a business must hand over its most sensitive data to a third party service provider—this requirement carries with it major drawbacks, as we will see. A recently conducted survey of nearly 300 IT Experts done by the Journal of Computer Information Systems found the three primary concerns are loss governance, service availability, and information security (Dutta, Peng, & Choudhary, 2013).

It would be fair to say that cloud computing has changed the way the business used to do. With the evolution of cloud computing, IT companies can get software to hardware and infrastructure to staff requirement on demand. Cloud service providers also fully mange the services which can be provided at any time. Cloud computing utilizes a combination of the internet (cloud) and computer technology (computing). It is broadly defined as methods to deliver information or services to customers who pay for what they use. It uses the architecture in which one provider is giving services to multiple organizations. This paper, I will be discussing about risk and challenges of cloud computing. My main focus on the paper will be over cloud, its standardization, challenges/concerns and current business transformation.

Moving forward 30 years to 1997, is when the term “cloud computing” was first used by information systems professor Ramnath Chillappa. Within a few years, companies began switching from hardware to cloud services; they were attracted to the benefits like the reduction in capital costs as well as an easing in IT staff; the number one benefit being efficiency.

Cloud computing is moving into the mainstream. Moving to the cloud might be a viable option for some consumers. However, there are many facets to consider before moving to the cloud. There are four types of clouds, public, private, community, and hybrid. All four cloud arrangements have pros and cons, and they need to be weighed before a decision is made. Two main challenges of clouds are security and privacy. These two main issues must be addressed prior to choosing a cloud service. As a consumer, you make the choice for how stringent your security and privacy are to your stakeholders.

Cloud computing enables businesses to deploy or subscribe to services as it needs them. A cloud features self-service, broad network access, centralized shared resources, and measurement of service usage. There are three widely accepted types of cloud service models. They are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each serves a different purpose and business may choose to use just one, two, or even all three of the cloud types simultaneously as the needed.

Cloud computing comes in three distinct implementations or models, each with its own pros and cons. The advantage is that each can be tailored to meet a specific need. The three different implementations are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). In IaaS, an organization uses the cloud to provide virtual resources, such as storage space for data or online databases. Amazon’s Simple Storage Service (S3) is an example of IaaS, with customers utilizing the S3 cloud to store information. PaaS implementations run on top of IaaS, giving the organization flexibility to implement customized applications, such as specific portions of Google apps. Finally, SaaS is the transition to almost all operations to the cloud. In SaaS, a small blade system is used to connect to the cloud through an Internet connection where all the software and major computing power is stored. Instead of having an OS installed on each desktop system, the OS and everything else needed is stored on the cloud servers and accessed through a web browser or custom plug-in. (Neamtiu & Dumitras, 2011)

Another disadvantage of cloud computing is that companies are no longer in control of their own data despite the fact that the data centers are very secure. When companies move to the cloud, they have to hand over the data to the cloud host company. However, this situation is improving as all cloud host companies provide 24/7 customer service.

Cloud technology innovation is emerging as one of the most popular issue for most IT practitioners and cloud computing is thought of as the future trend of development of the IT industry. According to Stanoevska (2010), enterprises should have an IT infrastructure that can reform itself rapidly to new business priorities. Cloud computing technologies, such as Cloud mail, Cloud platform and Cloud software services, provide an efficient work platform for enterprises. At the same time, Carling (2011) puts forward potential problematic issues in terms of the security of cloud computing. The future of enterprise cloud computing becomes increasingly controversial. Nevertheless, enterprises should base their future framework for Information and

Abstract – The idea of cloud computing was first introduced in the sixties. Today, cloud computing is widely used in everyday life. There are many advantages to cloud computing but with everything in life there are always disadvantages. This research will focus on how the dependability of cloud computing holds up with all the new evolving changes and updates to the cloud computing service.

Cloud Computing is collaborative, less expensive, and has gain an upper hand in the industry today through the use of the internet. However, cloud Computing can not be discussed without considering the risks that are associated with it, because most of the services are often outsourced to a third party. As a result of this it is difficult to maintain a
