Друштвени медији представљају неизоставни део модерног друштва и веома значајан облик социјалне интеракције. Друштвене мреже, као важан део дигиталних медија, одликује једноставно учешће корисника и бројност садржаја које они генеришу. Због значаја друштвених мрежа у промоцији усл уга, посебно у туризму, предмет анализе у овом раду су могућности промоције српских манастира на Facebook-u као једној од најзаступљенијих глобалних друштвених мрежа.

In this paper, authors have analyzed economic andsecurity aspects of server virtualization. The experimentalanalysis includes: the business value of virtualization and impactof virtual environments on computing and security parameters,with applying modern cryptographic systems for data protection.The experiment was designed simultaneously on the traditionalserver and virtual environment. The obtained results show thesignificant advantages of virtual environment in the form ofoptimal allocation and utilization of physical computing resources.Also, the results indicate a significant improvement of parametersin the information security, introducing of the virtual networkadapter which presents virtualized communication channelsconcept between the application server and database server.
