Usage of cloud systems for data storage has many advantages over the traditional approaches. It is already widely used and its popularity is still fast-growing. The systems must be implemented and maintained in a way that not only satisfies the performance and resource availability requirements, but also fully addresses the questions of security, privacy and data ownership. However, concerns related to those questions very often lead to considerations of a private cloud implementation. In this paper, we explore a private cloud implementation suitable for small to medium businesses. We introduce main types of cloud computing as basic service models and analyze private cloud systems features. Advantages and disadvantages in comparison to public cloud services are considered. Implementation of private cloud solutions in a lab environment allowed us to examine the ease of the setup and maintenance as well as the usability of the chosen solutions and their applicability for the target user group.
