Uzročno-posljedična povezanost računalstva u oblaku i kretanja troškova informacijsko komunikacijske tehnologije gospodarskih subjekata u Republici Hrvatskoj
Causality of cloud computing and ICT cost developments in Croatian companies

Summary/Abstract: When we analyze the effects of information and communication technology (ICT), usually the focus is onthe timeliness and ease of gaining the required information, or the functionality of an information systembuilt by that technology. However, an important factor in introducing ICT applications into a company iscertainly the cost of its implementation and maintenance. Given the rapid development of ICT and thefrequent need for its replacement and/or upgrading, there is also an issue of cost-effectiveness of replacingthe existing technological solutions with new ICT concepts, i.e., new infrastructure solutions. The issuebecomes more difficult as the technological leaps become longer and longer. One of these major technological leaps implied the development of cloud computing. The key question posed by businesses all overthe world, including those in Croatia, is about the cost-effectiveness of implementing this concept. Answering this question involves determining the existence of causal relationship between the implementationof cloud computing and ICT costs. The study conducted confirmed the existence of causality between theICT costs and cloud computing. This causal relationship is inversely proportional because the more we usecloud computing, the lower the ICT costs. Moreover, failing to use cloud computing means lagging behindmodern ICT and thus lagging behind at all operational levels. This indicates that the application of cloudcomputing is a necessity for businesses in the developed world, as well as those in the Republic of Croatia.
