You may have heard that a cloud server platform is more eco-friendly than a traditional physical server platform, but why is that? What does that really boil down to for energy and cost savings? The average server running today is being utilized at 8-15% of full capacity. This ensures that there is additional space if more computing resources are needed. However, with server virtualization cloud servers server capacity can be improved to 70-80% utilization. This allows for servers to be consolidated at about a 15:1 ratio, which is the true reason that cloud servers are greener. For every one server that is consolidated, there is a huge energy and cost savings: • 7000kWh of energy is saved per year (about 0 today, and energy costs are rising). • 4 tons of carbon dioxide emissions are removed (the equivalent of taking 1.5 cars off the road).

Additional energy savings come from the cloud service provider’s ability to power down under utilized servers during times of lower need without affecting service. As more resources are needed, the provider can simply power servers back on to accommodate the demand. Servers running idle can use just as much energy as when they are actively running. In addition to savings to the environment, there is a huge cost savings for companies. On average, after moving to a cloud platform, companies are seeing an 50% reduction in total cost of ownership. The truth is that with server consolidation, less resources are needed. Cooling, heating and power requirements decline. Tech staff resources can be reallocated towards higher corporate valued projects since less server maintenance, upgrades, and repairs are needed. Combining the fact that cloud servers are greener, with their ability to be more economical, reliable and scalable, it is no wonder that so many companies are moving to the cloud.

A Different Way of Computing 

I need a computer. Actually, I need the processing power of hundreds of computing hours. Heretofore, if I was a researcher running data or testing a model, that meant using solely the computing power available on my campus computing system. For a major operation, that might mean waiting behind other faculty and student projects, and then having to run my data over days at a time. Today, that computing power can be had at my fingertips in a matter of minutes – or even seconds.

Likewise, my email, my files, my programs were all formerly on my computer – or on my campus’ mainframe. Today, those operations – and my data – may reside on servers in Washington State – or in Bangalore.  And this may not just be for my computing needs. Today, it may be for my entire campus and all of the institution’s students and faculty.

Welcome to the world of cloud computing!

The Cloud Computing Concept 

The Economist reminds us that: “Computing has constantly changed shape and location—mainly as a result of new technology, but often also because of shifts in demand.”  We have seen revolutionary computing technologies – truly “game changing” concepts – come about roughly once each decade in the “modern era” of computing since around 1945 when computing came to mean computations performed by a machine, not by man. From the mainframe era of the 1960s to the advent of minicomputers in the 1970s, the personal computer in the 1980s, the growth of the Internet and the Web in the 1990s, and the explosion of cell phones and other smart, Web-connected devices in the past 10 years.

Now, many think that cloud computing will be “the next big thing.” Indeed, Gartner  believes that in the end, the impact of the cloud model will be “no less influential than e-business.”  If industry analysts are correct, we thus stand at an inflection point – a true paradigm change – in the evolution of computing.

The basic idea behind cloud computing is that anything that could be done in computing – whether on an individual PC or in a corporate data center – from storing data to communicating via email to collaborating on documents or crunching numbers on large data sets – can be shifted to the cloud. As can be seen in Table 1, cloud computing encompasses a wide variety of offerings, including: SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service).

Description

User Level

SaaS

“Software as a Service”

Companies host applications in the cloud that many users access through Internet connections. The service being sold or offered is a complete end-user application.

Developer Level

PaaS

“Platform as a Service”

Developers can design, build, and test applications that run on the cloud provider’s infrastructure and then deliver those applications to end-users from the provider’s servers.

IT Level

IaaS “Infrastructure as a Service”

System administrators obtain general processing, storage, database management and other resources and applications through the network and pay only for gets used.

Cloud computing has now become “shorthand” for the larger trend of computing services delivered over the Internet. From the perspective of the market analyst, IDC, cloud computing represents “an emerging IT development, deployment and delivery model, enabling real-time delivery of products, services and solutions over the Internet.” As one commentator recently characterized it: “Cloud computing — in which vast stores of information and processing resources can be tapped from afar, over the Internet, using a personal computer, cell phone or other device — holds great promise…to cut the costs, complexity and headaches of technology for companies and government agencies.”

Certainly, one of the hallmarks of cloud computing is that it enables users to interact with systems, data, and each other in a manner that minimizes concern about the underlying technology. According to the Cloud Computing Manifesto: “The key characteristics of the cloud are the ability to scale and provision computing power dynamically in a cost efficient way and the ability of the consumer (end user, organization or IT staff) to make the most of that power without having to manage the underlying complexity of the technology.”

The Economist captured the meaning of this trend in stating: “The plethora of devices wirelessly connected to the Internet will speed up a shift that is already under way: from a ‘device-centric’ to an ‘information-centric’ world….(and) as wireless technology gets better and cheaper, more and more different kinds of objects will connect directly to the cloud.” Technology guru Clay Shirky perhaps put it best when he said: “What is driving this shift is a change in perspective from seeing the computer as a box to seeing the computer as a door.” The emerging cloud computing paradigm is thus based on a “user-centric interface” that minimizes user concern over the supporting infrastructure. 

Overview 

How does this new, on-demand, information-centric model of computing fit in the world of higher education – and what does it entail for research, for collaboration and for communication in colleges and universities? This article examines the early evidence from the field and discusses the practical and institutional implications. It concludes with a Cloud Migration Strategy for college and university IT executives to follow as they seek to best integrate cloud computing into their overall IT strategies.

Cloud Computing in Universities Today

For universities, migrating to cloud-based services affords them the ability to provide improved collaboration and research capabilities, while at the same time, providing an opportunity to cut IT costs while providing the same – or better – levels of computing services. Magnified by the need to pare overhead costs at a time when public and private institutions are grappling with significant budget shortfalls, cloud computing allows universities to not just use the resources of commercial cloud providers – many of which are available to them either for free or at reduced costs. With the cloud model, students and faculty can take advantage of the ability to work and communicate from anywhere and on any device using cloud-based applications.

The benefits for higher education center upon the scalability and the economics of cloud computing. These will be discussed in subsequent sections.

Scalability of Resources             

One of the most important impacts of cloud computing will be the notion of computing power on-demand. One industry expert described this newfound power in the following manner: “When you radically democratize computing so that anyone has access at any moment to supercomputer-type capacity and all the data storage they need.” This “democratization” of computing processing and storage power could have profound implications in everything from scientific inquiry (by making no problem too big to compute) to new enterprise formation (by drastically reducing the need for upfront investment in IT resources – and the people to support and maintain them) to public agencies (by making IT more affordable and available to governments at all levels and in all locales). Thus, we may be seeing a truly new era, where through democratizing computing technology, this will help to bring “the benefits of high-powered computers and communications to all.”

Cloud computing is a revolutionary concept in IT, due to an unprecedented elasticity of resources made possible by the cloud model. In everyday use, elasticity is commonly thought of not just as the ability of an object to stretch out when needed, but to also contract as necessary (think of a rubber band or a bungee cord). In computing terms, elasticity can be defined as: “The ability of a system to dynamically acquire or release compute resources on-demand.”  Under the cloud model, organizations that need more computing power have the ability to “scale-up” resources on-demand, without having to pay a premium for that ability.  Say, for instance, that a researcher or a department has large, batch-oriented processing tasks. The individual or group can run the operations far faster than previously and at no additional costs, since using 1000 servers for one hour costs no more than using one server for 1000 hours. This unique attribute of cloud computing is a commonly referred to as “cost associativity,” and it allows for computational needs to be addressed far faster and far cheaper than in the past. In short, cloud computing gives organizations – even individual users – with unprecedented scalability.

Additionally, where in the past only the largest universities have had supercomputing capabilities cloud computing, with number-crunching capabilities available on an on-demand basis, affords researchers anywhere to scale their computing power to match the scale of their research question – bringing supercomputing to the mainstream of research. As Delic and Walker recently characterized it, cloud computing might just “enable new insights into challenging engineering, medical and social problems,” as researchers will now have newfound capabilities

With today’s advancement of technology, Information Technology resources and even network resources play an important role not only in the corporate world but also in educational institutions, personal use at home, and any individual that is inclined to use technology. The use of a computer today is enhanced by connecting it to the internet. But connecting it to the internet poses a possible threat to the computer devices. These threats are why it is important to maintain network security. The internet provides possible opportunities for unfamiliar threats including unauthorized persons, viruses, and worms.

Internet connections open a venue for a lot of useful software and easy information sharing across the globe. However, sometimes private networks handle sensitive information that is not supposed to be shared with outside users. This information is susceptible while on the internet to attacks, IP spoofing, and other intrusions. The worst case scenario is when managers find out too late that their system has been compromised and they have lost valuable information.

While there are security measures for computer networks, the sad reality is that most people don’t know the importance of internal network security systems. It is basically the most important component in network configuration as well as network management. An effective network will provide a secured information system to the entire company.

Internal security deals with detection and prevention of any unauthorized access to the computer network. These security procedures and techniques may come in the form of software that protects the entire network infrastructure from any illegal access, misuse, or any other threats that may destroy the integrity of the network. An effective internal security solution provides a safe venue for computers and programs to perform their operations in the most reliable and efficient way.

With a good internal security solution, the network will be ensured of its accountability, integrity, and confidentiality. It will be capable to withstand any external and internal threats such as network security issues, attacks, worms, and other intrusions. Network security solutions typically depend on the network usage. For home use, users can have security applications such as firewalls and encryption solutions. Other internal network solutions also include authentication and user verification, access controls, and intrusion detection.

An effective network security can bring a lot of benefits to the corporate world such as enhanced IT processes, productivity, and efficient services. It provides the most secured and protected data that meet the quality standards set by the company. Lastly a good security solution ensures that only authorized people can have access to the network resources of the company.
