Cloud computing is a modern concept in the field of computing and informatics, representing a distributed set of computing services, applications, access to information and data storage, without the user needing to know the physical location and configuration of the systems providing these services. Cloud computing offers a model for advanced use of digital technologies and programming that can be used by institutions and companies as a basis for development of applications and services. The main concept in building a cloud computing architecture is access to some applications, services or databases without storing them on an own system. Information and databases that build these applications are stored on a server or a unified server system located in another place or even in another country. The functioning method of this technology is similar to internet.
