注释,注释: The article deals with the issues related to the users’ access to the system of topological PC board layout without buying the license for the system because the price of the license may reach dozens or even hundreds of dollars which is not of economic benefit to the majority of developers. This leads to the growing popularity of cloud technologies that allow to get access to the design systems based on inexpensive licenses. Thus, the authors of the present article analyze different services of cloud CAD and define the most popular services. Then the authors compare different kinds of CAD PC board layout and offer to use Topological Router as the topological router created on the cloud. According to the author, Topological Router has the most beneficial features. In addition, the authors define the platform for deploying the cloud. The main research method used by the author is the comparative analysis of parameters and features of CAD PC boards and cloud deployment platforms. The scientific novelty of the research is caused by the fact that so far there haven’t been any practical implementation of WEB-oriented PC board design systems. The test case of the corporate cloud on the basis of the VMware platform has proved it possible to use cloud technologies in creating public access to the topological CAD. To deploy the full function corporate cloud and provide access to virtual CAD through web-interface it is necessary to install the additional server VMware vCenter Server 5.5.
