How does cloud technology work?

Take action

  • Talk to your local information technology specialist to see if they are utilizing or supporting cloud services in any way?
  • Ask your local information technology administrator to describe the local hardware infrastructure to compare to cloud infrastructure services you discover.

The Cloud is Not a Replacement for In-House Development

It is a myth of the cloud era that businesses can simply buy what they need and be less reliant on application development. One of the biggest surprises for many businesses is that cloud, mobile and social technologies often have made things more complicated, not less, for large enterprises. Supporting new cloud, mobile, social technologies have imposed more minimum requirements and expectations than ever before on builders of enterprise applications. The applications have to be faster, more flexible, and more responsive, meet much more rigorous security criteria, and meet much higher usability expectations with a social interface that is universally accessible on any mobile OS the employee chooses to bring to work. The days of just cranking out database-backed web forms ended years ago.

In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user's side decrease. The only thing the user's computer needs to be able to run is the cloud computing system's interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest.

Before we dig further into how does cloud computing work, first let’s understand what the term “cloud“ refers to.  The concept of the cloud has been around for a long time in many different incarnations in the business world. .

Cloud computing is becoming an adoptable technology for many of the organizations with its dynamic scalability and usage of virtualized resources as a service through the Internet. It will likely have a significant impact on the educational environment in the future. Cloud computing is an excellent alternative for educational institutions which are especially under budget shortage in order to operate their information systems effectively without spending any more capital for the computers and network devices. Universities take advantage of available cloud-based applications offered by service providers and enable their own users/students to perform business and academic tasks. In this paper, we will review what the cloud computing infrastructure will provide in the educational arena, especially in the universities where the use of computers are more intensive and what can be done to increase the benefits of common applications for students and teachers.
