摘要:AbstractCloud computing represents a potentially very effective solution to current problems linked to the need to decrease public budget expenditures. The solution is based on sharing the same solution by multiple users as well as on an opportunity of choosing a custom-made solution that would suit any office's particular needs. The aim of this contribution is to specify when to deploy cloud computing in the public sector and to compare the situation in the Czech Republic and elsewhere. A case study of cloud computing deployment in a chosen public sector institution–high school–will be used to illustrate the situation. The used research methods include document analysis focusing on cloud computing in the public sector. The data for the case study was collected by means of an in-depth interview with an IT expert. The data from countries using cloud computing in the public sector show that its deployment is meaningful. This conclusion is confirmed by the case study, which shows savings and benefits from this technology's deployment.
