Cloud Computing – Understanding The Concept Behind

It has become a widely known and accepted fact that the technology has managed to take over and change man’s professional outlook, especially that of business completely. Internet and technology has completely revolutionized the way in which work is done and looked at. And cloud computing can be said to be one of the many facets of technology that is fast becoming a trend among organizations.

The Concept of Cloud Computing

The first question that the mind buzzes with here is what exactly is cloud computing? What is it all about? To put it in absolutely simple terms, one could say that it is just another variety of computing – the operating mode of which banks on the sharing of “computing resources“, instead of allowing local devices handle applications.

The concept would be easier to comprehend if one splits the term into two parts. The word “cloud” that has been clubbed with “computing” to derive the resultant phrase  can be considered a metaphorical reference to the internet, thereby, coming to mean a system of computing that uses the internet as its base – by application of various kinds of services, such as of storage, servers and applications made available to the devices of an organization by means of the internet.

How is Cloud Computing Different from Traditional IT Services?

Cloud computing is an altogether different deal from the traditional IT services. How so? In the case of traditional IT schemes, organizations are the owners of the licenses of software and hardware, with them outsourcing certain development of applications to a third person. In this case, the means of achieving the end becomes quite significant an affair , but with the progress in the field of technology, things have begun to change its course – focusing only on the output and not on the way the output is achieved. With the introduction of cloud services, the clients are now more focused not on the hardware and software used, but on the service they received and the output they produced.

Cloud backup services is no more a hypothetical concept today. There are a number of organizations offering cloud computing services. Applications are accessed via web browsers and the terms and conditions of use are monitored by “legal service agreements”.  Surprisingly, cloud backup services available on the block can now be deployed on a public scale made available by paying a certain amount of money as fees on a private scale. The most prevalent forms of cloud computing environments today are the “Infrastructure-as-a-service”, “Platform-as-a-service” and “Software-as-a-service”.

Defining  Terminologies

Infrastructure-as-a-service

This is the environment which makes the “computational infrastructure” over the net along with an assortment of interfaces facilitating communication.

Platform-as-a-service

This is the environment which hosts platforms for the development of various applications. It makes resources readily available so that hosting of larger applications becomes easier for the organization.

Software-as-a-service

This is the environment which makes the use of “business specific” software developments by third parties possible, by hosting “application specific” software.

The world is evolving differently today, nothing is constant but change. If organizations are not flexible and pliant to this call for change and advancement, then it can not expect to survive long in this era where cloud is within reach.
