1. Abstract.

The term "Cloud Computing" has been mentioned for just under two years in relation to services or infrastructural resources, which can be contracted over a network. Thus, the idea of renting instead of buying IT is nothing new. And so, Cloud Computing has many antecedents and equally as many attempts to define it. The players in the large world of clouds are Software as a Service providers, outsourcing and hosting providers, network and IT infrastructure providers and, above all, the companies whose names are closely linked with the Internet's commercial boom. But, all these services in combination outline the complete package known as Cloud Computing – depending on the source with the appropriate focus. That which long ago established itself in the private environment of the Internet is now, noticeably, coming to the attention of businesses too. Not only developers and startups but also large companies with international activities recognize that there is more to Cloud Computing than just marketing hype. Cloud Computing offers the opportunity to access IT resources and services with appreciable convenience and speed. Behind this primarily, is a solution that provides users with services that can be drawn upon on demand and invoiced as and when used. Suppliers of cloud services, in turn, benefit as their IT resources are used more fully and eventually achieve additional economies of scale. There are substantial arguments for the adoption of Cloud Computing: the lasting improvement of cost structures, faster reaction to changes in the market and potential for increases in productivity. Cloud Computing offers flexibility whilst simultaneously reducing costs – with the positive side effect of sustainability.


“The data center of the future could be based in the cloud.” (Jason Staten, Forrester) [Herrmann 2008] However, much of Cloud Computing is still a vision. This becomes especially evident if large companies wish to make use of the possibilities. Then, at the latest, questions arise about security and quality of service or, subsequently, whether the proffered services can also effectively meet the company demands of supporting the business processes. Legal aspects such as the storage of data swiftly become more weighted. Professional providers of Cloud Computing for enterprise customers must not only meet these challenges, but also develop concepts in order to do so in a transparent, cost-effective manner.


2. Introduction to Cloud Computing.

2.1. A historical background. It is conceivable that August 24, 2006 will go down as the birthday of Cloud Computing, as it was on this day that Amazon made the test version of its Elastic Computing Cloud (EC2) public [Business Week 2006]. This offer, providing flexible IT resources (computing capacity), marks a definitive milestone in dynamic business relations between IT users and providers. The target of Amazon’s offer were developers, who had no wish to hold their own IT infrastructure, and instead, hired the existing infrastructure from Amazon via Internet. Nobody at this time spoke of Cloud Computing yet. The term first became popular in 2007, to which the first entry in the English Wikipedia from...
