Short and sweet: Cloud computing and its security

The emerging and developing technology of cloud computing may be defined as an availability of scalable and easily accessible virtualised resources allowing the various paradigms. Cloud computing thus helps to reduce cost of ownership and management of virtualized resources, lowering the market entry threshold to new players and enabling provisioning of new services. Nevertheless, it is not massively adopted mainly due to tremendous security challenges. Therefore, this paper aims to provide a short overview of cloud computing and its security. The intention is to provide an insight into the basics of the field from the beginner's point of view, including cloud computing security challenges and benefits, as well as current security situation in major cloud players. With this in focus, this paper presents the starting point for our future work, which will follow the world's trends in this filed in order to increase the utilization and adaptation of this promising technology.
