Cloud computing is becoming the dominant method of using information and communication technologies in companies. Today is the age of cloud computing technology in the IT industry. Internet-based cloud computing has the most powerful computer architecture. It counts on a compilation of integrated and networked hardware, software, and Internet infrastructure. It has various advantages on the network and other computers. Cloud computing provides computer, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that provides the services. Parallels with this concept can be drawn with power grids, where end users consume energy without the need to understand the component devices or infrastructure required to provide services. Cloud computing describes a new add-on, consumption, and delivery model for IT services based on Internet protocols, and typically involves the provision of dynamic scalable and often virtualized resources. This is a by-product and a consequence of the ease of access to remote computer measures. through the Internet. In this paper, we have looked at the main characteristics of the cloud computing environment, as well as its advantages and disadvantages. It is also explained what its application is, not only internationally but also services in Croatia.
