The thesis describes development of application used for visualization of data centers monitoring. The application development is based on 42ITy project, which has support for monitoring of different parameters of data centers, but all data provided by that project support is available only in text format. Technologies and tools used for application development are described at beginning of thesis. That description includes React, JSX syntax, VirtualDOM, Redux, Node.js and Three.js. Subsequently, capabilities, advantages and disadvantages of 42ITy project are described through the architecture scheme and the textual descriptions. In the next chapter, the application sign-in page and its sections are explained, as well as the advantages and disadvantages of the page itself. Steps of software development and layout design of application are in detail explained in the middle part of thesis. Each development and design step is described chronologically how they was implemented. Before any model could be visible on scene when positioned, it is required to add camera and background light. After base scene setup, the server room is added which in this example is presented as square model. Inside of that server room multiple square models are added which in this case are presenting server racks. Inside of every server rack, multiple square models are added, and in this case those squares are presenting server units. It is also explaining object texture mapping and describing all problems that appeared while implementing previously mentioned example. At the end of the thesis, there is installation guide for all necessary tools needed for proper running of the application.
