Cloud computing is an approach to computing that leverages the efficient pooling of on-
demand, self-managed virtual infrastructure that is consumed as a service.
The launch of this model of data processing requires the appropriate hardware and software
infrastructure, which currently are very expensive. Another problem is the law that is not adapted
to modern IT solutions. Nevertheless, cloud computing is the fastest growing part of the IT market.
This article provides information about benefits and limitations of public and private cloud
computing. It focuses on definition of cloud computing, describing proposed solutions for private
cloud computing offered by leading software manufacturers and financial and law factors that can
decide about successful migration to the cloud
