Cloud Based Computing
By: Alex Hornberger

Introduction

Cloud based computing is a new and very misunderstand piece of technology. Businesses moving their IT services to the “Cloud” will cut expenses and increase productivity. In this report I will discuss what cloud based computing is, how it can benefit and business.

To better understand what cloud computing is, the key components must be understand first. When referring to the cloud, that is nothing more than the internet. The internet is a logical place hosted on physical hardware. (Ricadela,2007) Cloud computers are multiple PC’s housed on a single piece of hardware. This allows a company to get the most out of their IT investment. Instead of running one single operating system on a piece of hardware, it gives the ability to run multiple logical PC’s on a single piece of hardware simultaneously. This is important due to the amount of money that can be saved by a business, PCs costs any were from $300 dollars to $2000 dollars. To begin to utilizing cloud computing a business has to purchase a mid to high end server which will house all of the virtual machines. Each virtual machine will only use the designated amount of resources, this gives an administrator the ability to assign resources as needed.

Challenges

There are many challenges facing a business to adopted the Cloud Computing. One challenge is understanding the way it functions and works, most business owners chose not to get involved in how their computer systems work in the first place. Introducing a new way of functioning could immediately scare them away from adopting this technology. A second challenge cloud computing is facing is the cost of an implantation and migration. When moving to a cloud solution, form physical hardware to the cloud could be very difficult and timely. Migrating and maintaing all of the services and data will require a very skilled and experienced engineer, which are very hard to find due to the lack of production environments. (Brodkin, 2008)One of the biggest challenges facing cloud computing is security. In a physical standalone network if one box (Server) was compromised, quarantining1 and troubleshooting that was relatively simple and straight forward. With one server controlling the entire infrastructure, one minor vulnerability could comprise the entire network. The last challenge facing cloud computing is performance. When going across the internet to access any thing, speed and latency become an issue. Increased amount of failing point make expected performance hard to deliver and guarantee.

Argument

I do believe there are challenges in front of cloud computing before it is an well accepted technical service. The biggest challenge I believe it is facing is performance. When access the computer through the cloud (internet) the performance is effected by speeds provided by an ISP. If large bandwidths are not provided to the housing office of the cloud server, performance is going to be effected and impacted tremendously. I do not believe security is a bigger risk then a normal physical computer network. If a cloud server becomes compromised it is because of the same reasons a physical server would taken over. This can all be due to a lack of administration and security policies.

Conclusion

In conclusion there are many befits and challenges facing cloud computing. There is always a security risk present when utilizing computers. The saving possibilities that come with moving to a cloud solution, will gain the attention of any serious business owner, and then increase the popularity and use of cloud computing.

Cloud Technology

...Cloud Computing Introduction Cloud computing is the idea of deploying groups of remote servers and software networks that allows remote access to computer resources. Cloud computing is the term that describes the delivery of computer as service rather than a product. The internet is like a cloud. Cloud computing users use the services of the computing. They don’t have ideas about the location of the computer infrastructure. Cloud computing provides computation, software, data access, and storage resources to its users. If businesses look for the computing services without establishing computing infrastructure, the cloud can be the solution to achieve the objective. How Cloud Computing works? Cloud computing changed the way of computer uses. It changed the concepts of use web and store the data. Cloud computing is the structure which was used by the sites like Google, Facebook, Twitter, Dropbox. Let’s consider that the cloud consists layers. There is the back-end layers and the front-end layers. Front-end is the public part and users can interact with the front end layer. For example, when we access on Google Drive, the public user interface is visible to us. The back-end consists of hardware and software architecture that delivers the data to the front-end. There are many computers integrated to work together in the cloud technology. The front-end application can use all available computer power to provide the services to end users. Cloud computing uses the network...

...370-01 2/12/15 Cloud Computing Cloud computing involves servers and software networks; this allows centralized data storage and online access to computer services or resources. In other words, users can access software applications through the internet or any other networks through the cloud application provider. Cloud computing is just a term used to describe this process. Many things can be achieved using cloud computing as long as it’s properly done and maintained. There are various positive outcomes that derive from this innovative business approach. However, some corporate executives would prefer not to use cloud computing due to security and privacy issues. The main concern is that people’s important data and personal information would not be secured, as well, as it should be and is at risk of being compromised. With this being said, there are potential positives outcomes as well as negative ones. Cloud computing is hosted on remote servers, which receive the data that is sent to “the cloud”. Using this type of accounting software saves businesses from having to install and maintain software on each individual desktop computer. It also allows employees, in remote or branch offices, to access the same data and the same version of that same software. There are three different types of clouds: private, public and hybrid. (Cloud computing accounting software) Each of these clouds has its own specifications relating how and where it will operate. A private cloud for example...

...[pic] Cloud computing in general isn’t a term that can be defined with one specific definition as different people from all over the world each have a different understanding of the term cloud computing. Hence the best way to effectively explain the term is to explain it using different examples. Some people believe the term to mean another way of describing IT (information technology), others use it to mean any computing service provided over the Internet or a similar network; and some define it as any bought-in computer service you use that sits outside your firewall. As you can seem, there is no straightforward definition for the term and therefore best way to understand it is to learn about how it works. The main point of cloud computing can be summed up with this one short sentence: “Access your data anytime and anywhere” What is the difference between cloud computing and old fashioned personal computing? An important thing that differentiates cloud computing to the now old fashioned and declining personal computing is the location where all the data is stored. In cloud computing the data is stored on a remote database operated by a third party which can be accessed from most places, as the main requirement to access this cloud storage is only an Internet connection. In personal computing, all data is stored on a hard drive or another form of data storage device such as a usb drive, and once the data storage limit is reached a bigger hard drive...

Cloud Computing

...your information or data would reside on the Cloud (Internet). As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing", the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud", including conventional outsourcing. Cloud computing comes into focus only when you think about what we always need: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends ICT's existing capabilities. Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging. ______________________________________Cloud computing - The Concept Cloud computing is Internet ("cloud") based development and use of computer technology...

Pros and Cons of Could Based Computing

...Pros and Cons of Cloud Computing in Businesses Cloud computing has been a controversy in Information Systems since Salesforce.com, the first of its kind, was released in 1999. According to the National Institute of Standards and Technology, “cloud computing is 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” (Mell). In other words, the cloud uses the Internet to store, access, and process data. Before cloud computing, the only other way to store and process data was through in-house servers, which are simply a server located within the company. The invention of all new technology brings controversy because the amount of issues that could come from it must be compared to the amount of benefits. There are three different types of cloud computing, all of which can be incredibly beneficial for both personal and business use: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) (Turim-Nygren). Although they all function similarly, they take on their own roles and process information differently. The most commonly known is cloud storage such as Dropbox and Google Drive, which are categorized as SaaS. The pros and cons of cloud computing have been debated over the past decade, and individuals...

It cites examples of enterprises that have adopted the concept, stating the success or lack thereof. It also discusses the possible future of cloud computing. WHAT IS CLOUD COMPUTING? Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that is often used to represent the Internet in flowcharts and diagrams. See Figure 1. A visual representation of the Cloud including some companies that offer cloud based services. A cloud service has three individual characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour.

...days, organizations are looking for IT to operate more efficiently and help to reduce the overall costs. The concept of outsourcing has contributed to this development by transferring entire business functions to an external service provider. A recent phenomenon in the domain of outsourcing is called Cloud Computing. “Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically re-configured to adjust to a variable load (scale), allowing also for an optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by the Infrastructure Provider by means of customized SLAs” (Vaquero, 2009). The arrival of the Internet has accelerated the commoditization of IT by providing a perfect delivery channel for generic applications. More and more, companies will fulfill their IT requirements simply by applying pay-as-go utility models, infrastructure services with value added platform services or fee-based infrastructure services with value-added application services (Zhang & Zhou, 2009). In essence, users of cloud computing “outsource” their data processing needs to a third-party...
