From the fact that there are different approaches to the definition of the term cloud computing follows that the approaches to the description of its inner organization also vary. In the next part, the thesis looks into these approaches and briefly compares them. It further describes the economical model of this way of providing IT services, which is a result of the approach developed within the technological and economical Software-as-a-Service model. Attention is paid to the basic technological questions of cloud computing, i.e. mainly to the design of services, management of databases, data safety and scaling of the computing resources. The final analysis of services provided within cloud computing is first done vertically, i.e. it is a comparison of the different types of services relating to the individual layers of the technological model, starting with the provision of hardware and computing services, over platform services to the Software-as-a-Service layer of the model. Subsequently, a comparison of services of several big players is made in the individual layers, i.e. horizontally. The thesis focuses on the on-demand way of providing IT services, currently known as cloud computing. Attention is paid specifically to the organization and interoperability of the provided IT services within cloud computing, as understood today by the expert public and commercial sphere. First the thesis deals with various possible definitions of the term cloud computing, it summarizes these approaches and attempts to outline the term and its determining attributes. This outline is then followed by describing the historical development of the distributed applications and older models of providing ICT services, from which cloud computing originates. The goal of the thesis is to describe the issue of classification of services in cloud computing and make the above-mentioned comparisons in an clear way and based on suitable metric. As a conclusion, the author presents his view on the future of the cloud computing and sums up the whole thesis.
