Data Centers are controlled facilities built with the express purpose of housing complex IT systems. They are usually built with highly advanced climate control equipment to moderate both temperature and humidity. Also, measures are installed to suppress fire should a fire break out. Another key aspect of a proper data center is the use of redundant power supplies which would allow the center to operate even if the power grid fails or blacks out. Like the redundant power supplies, redundant data communication connections are also installed. The last key component of any data center is security measures which control access to the data room as both a protection of the physical components, and the digital information which they provide. These centers allow the companies who use them to receive sure-proof technology support without necessarily having to go to the effort of running the center themselves.Because data centers are essentially a large collection of servers and other computer equipment, they are sometimes referred to as ‘server farms.’ The moniker is appropriate: generally quite large and like a farm populated with animals require care and attention to ensure that everything runs smoothly. The largeness of data centers actually runs back to the original computers.Before the advent of personal computers in the 1980’s, individual computers were massive machines which took up entire rooms. They required climate control to prevent overheating and security to protect the machines. Does this sound familiar? Many of the current practices have their roots in those established with the gargantuan computers of yesteryear. However, the boom of data centers didn’t happen until the 1990’s, after both the personal computer and internet had taken off.The 1990’s saw the rise of the internet. In order for companies to take advantage of the internet they needed servers. Once companies needed the servers to run their businesses, and once networking infrastructure was developed that allowed servers to be placed in their own room, the data center was born.Due to the great expense involved in creating a data center, small companies couldn’t practically build their own. At first large companies built their own Internet Data Centers to provide 24/7 access to the internet and support to ensure their systems were constantly available. Over time data centers migrated to the private sector.Currently operated by private companies which offer managed hosting to their clients. With the introduction of scalability within the data center even small businesses can take advantage of well-managed data centers without having to build their own. Also, managed hosting allows clients to not spend man power on the upkeep of the data centers. While current data centers are designed and operated according to industry standards, those standards are under constant development affecting how private companies operate and develop their centers.
The Iridium constellation was designed by Motorola to provide Mobile Satellite Telecommunications Services (TSM) with global coverage. Its name comes after the element Iridium (Iridium) which has an atomic number of 77, equivalent to the number of satellites in the constellation included in the original design. This system aims to provide voice and data communications service by using portable devices in the areas outside the coverage of traditional communication systems.At present, solutions provided by Iridium, which were bought and relaunched by new partners, are actively used in vertical markets such as oil, mining, ecotourism and military. After the events of September 11, 2001, U.S. security agencies have been using Iridium solutions as their preferred system of mobile voice satellite telecommunications. Only Air Force United States currently has over 25,000 active iridium satellite phones.In 2010, the Iridium satellite phones cost more for modern and unique production, the Iridium 9555, is approximately $ 1,500.00 in U.S. The communication cost per minute is about $ 1.30. The cost per minute is independent of the country they originate or terminate calls, but there are no roaming charges. Iridium has a system for sending and receiving text messages that can accommodate up to 150 messages of 160 characters per month free of cost. 9505A Iridium phones and the new 9555 can also send emails directly using the keypad. The cost of each email sent, which can have a maximum of 160 characters is about $ 0.60Iridium launched the service of OpenPort in 2009, focusing primarily on maritime segment, which allows data transmissions up to 128 kbps with global coverage. The current cost of OpenPort terminal is approximately $ 5,500.00 and the cost of transmission/reception of data is approximately $ 5.00 x Megabyte. In the late 2009, Iridium had already sold OpenPort 1000 terminals. OpenPort received a mixed review for service but it expected the system to function optimally in the first half of 2010. It is estimated that the Iridium system now exceeds 300,000 users.Today, different types of users such as first responders, fisherman, businessman, adventurers, pilots or members of the governments are using the Iridium satellite phones for daily operations.
