In today's society data centers play a crucial role in IT but also in every field of human activity. Thousands services, businesses and organizations use data centers. Thus, data centers differ depending on the target audience and in addition to this form the standards and the services offered. Additionally, understanding the technological developments in data centers are changing in order to adapt to changing needs. Thus, operators are concentrating their attention on security, energy saving, providing space and optimization of speed. In this study, we will deal with the structure, requirements, design and categories of data centers. In particular, the first section will be an introduction to the data centers, classes algorithms they use, their separation and the structure of a data center. The second chapter will be reference to the frequent problems of data centers and in matters relating to their safety. In particular, it will be set the security protocols used. The third chapter is related to the analysis of the functional requirements of data centers, focusing on the key operating points. The fourth chapter analyzes the architecture of data centers and marked the most important in Europe. The next section the fifth, describes green data centers, their management techniques and the technologies applied to save energy in them. Finally, the sixth chapter the thesis deals with the case studies of three large companies and their centers describing the methodologies followed in order to implement more efficient power management techniques.
