Growth of local area network Observatory associated with employee needs to access network resources has led to an increase in the number of computing and network devices. Until recently, we tested performance of these systems excellent manual and most of the problems and faults detected already on the fact the accident occurred. For a small number of network nodes, manual monitoring is not a significant problem, but with increasing the number of nodes troubleshooting becomes a very difficult task for network and system administrators and outage in work of netwok services Observatory may becomes critical. Therefore there was a need to automate the monitoring service network resources and servers.

The need for transmission and storage of large amounts of scientific data in the project space radio telescope ”Radioastron” required us to organize a reliable communication channel between the tracking station in Pushchino and treatment centers in Moscow. Network management data requires us to an integrated approach and covers the organization secure access to manage network devices, timely replacement of equipment and software upgrades, backups, as well as documentation of the network infrastructure. The reliability of the channel is highly dependent on continuous monitoring of network and server equipment and communication lines.

Now a day the task of comparative analysis of sample sources from different astronomical catalogs is becoming very topical for astronomers. It is useful both for the same spectral range data and for their cross-analysis for different spectral ranges. It is also important, that the real data from astronomical instruments is placed on-line. For the above purposes we are developing a website for the PRAO ASC LPI (www.prao.ru) and, based upon it, the Radio As-tronomy Data Center (RADC). The RADC is a system for  storage and processing of radio astronomical data. Here you can find a collection of tools for preparing radio astronomical  observations, which includes a base set of main astronomical catalogues useful to radio astronomers, as well as a database  of observation results from the Observatory.

In modern astronomy the problem of the big data obtained during scientific experiments is very actual. One of the perspective approaches to the solution of the problem of processing of superlarge volumes of experimental data in real time is the use of the technology of cloud computing which assumes ensuring remote dynamic access of users to services, computing resources and appendices on the Internet.

Singular Spectrum Analysis (SSA) of Global Mean Sea Level (GMSL) and Global Average Earth Temperature (HadCRUT4) data revealed pres- ence of quasiperiodic components with periods of 60, 20 and 10 years in both time series. 60-year component of sea level is anticorrelated with long-periodic changes in temperature, while 10 and 20-year components are correlated. The question what can be the nature of these common oscillations is discussed.

Since the work of a unique space radio telescope in the international VLBI project "Radioastron" extended to 2017 the transmission and storage of large volumes of scientific and telemetry data obtained during the experiments is still remains actual. This project is carried out by the Astro Space Center of Lebedev Physical Institute in Moscow, Russia. It requires us to maintain in operating state the high-speed link to merge into a single LAN buffer data center in Puschino and scientific information center in Moscow. Still relevant the chanal equipment monitoring system, and storage systems, as well as the timely replacement of hardware and software upgrades, backups, and documentation of the network infrastructure.

On the Pushchino Radio Astronomy Observatory of Lebedev Physical Institute by radio telescope BSA (Big Scanning Antenna) in 2012 started daily multi-beam observations at the frequency range 109- 112 MHz. The number of frequency bands range from 6 to 32, while the time constants range from 0.1 to 0.0125 sec. This data is an enormous opportunity for both short and long-term monitoring of various classes of radio sources (including radio transients), the Earth's ionosphere, interplanetary and interstellar plasma monitoring, search and monitoring for different classes of radio sources, etc. A specialized database was constructed to facilitate the large amount of observational data (http://astro.prao.ru/ cgi/out_img.cgi ). We discuss in this paper method of allocation from the database for impulse data of various types. By using the database allocated 83096 individual impulses in declination from +3 to +42 degrees for July 2012 – October 2013 from pulsars, scintillation sources and so one. In result we constructed homogeneous sample suitable for statistical analyzes.

From 2012 on radio telescope BSA FIAN multi beams diagram was started. It capable at July 2014 daily observing by 96 beams in declination -8 .. 42 degrees in the frequency band 109-111.5 MHz. The number of frequency bands are from 6 to 32, the time constant are from 0.1 to 0.0125 sec. In receiving mode with 32 band (plus one common band) with a time constant of 12.5 ms (80 times per second) respectively produced 33x96x80 four byte real and so daily we produced 87.5 Gbt (yearly to 32 Tbt). These data are enormous opportunities for both short and long-term monitoring of various classes of radio sources (including radio transients) and for space weather and the Earth's ionosphere monitoring, for search for different classes of radio sources, etc. The base aims of our work are: a) to obtain new scientific data on different classes of discrete radio sources, the construction of physical models and their evolution - obtained on the basis of the clock continuous digital sky radio monitoring at frequency 109- 111.5 MHz and cross-analysis of data from third-party reviews on other frequencies; c) launch the streaming data on various types of high-performance computing systems, including to create a public system of distributed computing for thousands of users on the basis of BOINC technology. The BOINC client for astronomical data from the monitoring survey of the big part of entire sky almost have not analogies. We have some first science results (new pulsars, and some new type of radiosources).
