In our blog on Habré we tell how the different companies build the IT infrastructure, and we cover the technologies which are used for work in clouds. Today it will be a question of the demanded tool for balancing of loading — VMware DRS.
In our blog on Habré we already told about experience of the real companies which have decided to pass to use of IaaS-clouds — among them, for example, service of armoring of Hotels.ru hotels and network of postamat of PickPoint. In our today's material — the story how clouds are used by the Center of speech technologies.
When I meet developers of Linux-containers, I first thought to refuse. To go 500 km to Moscow and back, to walk day, and I after all even not the developer, I am the system administrator who uses the OpenVZ technologies in the work …
But, having read the program, has understood that the meeting is expected not only and not so much developers, but also active users of this fine creation from Parallels. And having put the last beta of Virtuozzo 7 also has made to itself the list of questions which it would be desirable to clear.

Eventually there comes the moment when old constructions come to uselessness on the direct assignment and it is good that there are companies which give the second life such, apparently, normal, but in too time to interesting objects. Here and premises of the former department store McRae's of the city of Jackson the Venyu company has decided to turn into data-center. The department store has been open in far 1955, and its building is entered in the National register of historical places of the USA as it was the first suburban shop with full range of services of the capital of the State of Mississippi.
Data-centers — it in literal sense the place where there lives the Internet, is nerve ganglions of the Wide Area network. Nevertheless, the organism, system, grows, and here possibilities of data-centers remain former, and for all planet of it is not enough any more. Now the Silicon valley and technicians from around the world try to solve problem of connection of developing countries and certain regions remote from network infrastructure on decent distance, to the Network by means of non-standard tools and technologies.
The main initiators — Google, Facebook, Ilon Mask, Bill Gates and Richard Branson. Meanwhile time frames of the projects realized by the specified companies and their heads not too accurate, but it is not necessary to doubt their implementation. Let's look that the powers that be for the sake of connection still of the regions remaining autonomous and why are going to do.
The SWITCH company implements very ambitious project on creation of campus of data-centers of "SUPERNAP Tahoe Reno Industrial Campus" in Nevada now, Rino. The total area of site after completion of building of this object will make about 603 869 sq.m. Here some data-centers, one of which will become the largest in the world will be placed at once. Until now the largest of the existing data-centers was DTs Range International Information Group located in China. The cost of implementation of idea will make some billion US dollars (though it was initially going to invest 1 billion).
As for the largest data-center in the world, "SUPERNAP Tahoe Reno 1" with total area of 111 483 sq.m will become it. And it only the first of seven TsODOV which will be constructed. It is interesting that the campus from Rino will not be the first for the SWITCH company: in the USA "Las Vegas Digital Exchange Campus" where construction of nine data-centers is already complete already works, three more is going to construct. On completion of construction this campus will be most the DTs large group in the world, with total area about 1 746 577 sq.m.
We have started new service: reservation of router with use of the VRRP protocol ( abroad it is known under the name failover IP. As far as we know, in Russia to us anybody similar did not do anything. Service will be interesting first of all to those who would like to provide constant availability of business and significant Internet resources, but thus does not possess for this purpose sufficient technical opportunities: has neither own autonomous system, nor the block of IP addresses, connections to providers under the BGP protocol. We will in detail tell about features of its technical implementation in this article.
And business at all not in shortage of means or features of the Chinese TsOD — they same, as well as everywhere. Here only environment in China differs in the increased level of the contaminating substances, some of which accelerate corrosion of separate elements of the equipment. In some regions of the People's Republic of China the level of pollution of the atmosphere on many indicators considerably exceeds norm (occasionally, in tens times).
One of the most effective (and economical) ways of cooling of data-center is frikuling, that is use of external air for decrease in temperature of the equipment. The Frikuling, among other things, is also one of the most "green" methods of cooling of data-center as here both energy consumption not too high, and the equipment is required not so much (of course, all this with known reservations). But here trouble — in China it is difficult to use frikuling.

TsOD Inoventica is placed in the Sudogodsky region of the Vladimir region and is the first cloudy TsOD of Inoventica Group of companies. It is put in commercial operation in February, 2012.
TsOD has the following advantages:
The modern high-quality equipment from the HP company;
