Big Data refers to volumes which exceed the capacity of current online processing and storage systems. Public data and online data search are hampered because data sets remain scattered. Data storage is a technology issue which seems to be solvable soon by cloud computing, but at this moment a largecapacity and low-cost storage solution represent a long-term challenge which requires new paradigms and research. Big Data is not only narrowed to data viewpoint, but it has surfaced as a stream that includes combined technologies, tools, and real-world applications. The paper exhibits a simple, general and short introduction of Big Data from Internet of Things (IoT) devices. The purpose of this paper is to analyze different technologies used for storing and managing Big Data for research purposes.

Video conferencing has been commercially available since the video technology has become accessible on a variety of equipment, from room-based to handheld devices. The technology has also reached the point where it is viewed as a necessity and not just a nicety. The ubiquity and accessibility of video conferencing technology can save time and money across the spectrum of business processes, especially when comes to call centers. We propose a solution that can develop the communication with callers and provide a large impact on customer retention. One of the major issues regarding customer satisfaction when interacting with call centers or other types of customer support services is related to the resolution efficiency (solving the customer inquiry during the first contact), this is highly dependent with the communication solutions between the call centers department. But one thing is keeping videoconferencing from becoming a more standard form of communication: the technical difficulties that all videoconferences occasionally experience. The frustrations of video conferencing, though usually brief and irregular, may at first seem to outweigh the benefits. Connectivity problems can keep this from happening and are thus one of the most frustrating technical problems experienced by video conferences. The aim of this paper is to experiment a multimedia customer interaction platform and test the performance of a virtualized web conferencing solution focusing on the occurrence of technical difficulties associated with smooth transmissions that could result from software, hardware or network failure.
