Towards the end of the year, 2016 is coming to an end. Looking back on the important events that have taken place in the data center circle in the past year, everything is still vivid but will eventually become history. Data center development depends on technology-driven, and many information technologies are tailored to the data center. In 2016, some new technologies emerged in the data center. At the same time, some of the technologies proposed earlier may be neglected but were sought after by 2016. Technology is like a "star", but it also has its own life-time. Maybe when it is finally won, sometimes even you can not believe it. Now, let's take a look at what data center technologies are hot in 2016 and are widely accepted.
Fog calculation
Fog computing was not proposed in 2016, and was introduced by Cisco as early as 2011, with a detailed definition in 2012, except that cloud computing was booming and not many people were concerned with fog computing. Fog Computing is an extension of cloud computing and an extension of cloud computing. So fog computing has been inextricably linked to cloud computing since its inception. Cloud computing more emphasizes the use of the network to centralize the computing resources to provide the overall computing power of the data center, this technology is good, but more suitable for those large data centers, but in more small and medium sized data centers but no useless. Unlike cloud computing, the architecture adopted by fog computing is more decentralized and closer to the edge of the network. It allocates computing, communication, control and storage resources and services to users or devices and systems close to the user. Fog calculation is based on small clouds such as personal cloud, private cloud and enterprise cloud. For cloud computing, fog computing is a powerful supplement. As the maturity of cloud computing and data center in the actual deployment of such a problem encountered when the thought of the fog computing at this time, the use of fog computing can solve some cloud computing can not solve the problem, so the fog calculation up Fog computing has become a cloud computing supplement.
Blockchain
Blockchain is the underlying technology of bitcoin, which can be understood as a mechanism of public accounting. In fact, bitcoin is just one of the most famous applications of blockchain, and blockchain technology is recommended by financial institutions such as Citibank, JPMorgan and UBS. Blockchain is a distributed peer-to-peer network that does not have a central control point and uses a distributed collective operation to implement a set of tamperproof and trustworthy database technology solutions characterized by decentralized storage, Highly transparent, not easily tampered with. Popular point that is the use of computer programs in the entire network record all the transaction information "public large ledger." The data block records transaction data across the entire digital currency network, and these data are shared by all digital currency nodes. Through the data block, we can check the history of each digital currency transaction. Through blockchain technology can be a lot of seemingly useless data in the data center effectively combined, the interlinked data to form a blockchain, such data makes sense. Analysis of these related data can often yield very meaningful results, much like large data techniques, analyzing large amounts of data and identifying some of the laws that can be used to generate revenue for the data center Blockchain technology is also true. The blockchain was proposed at the end of 2008, except that it has not received much attention in recent years. Until 2016, R3CEV (R3 Blockchain Alliance) and Microsoft signed blockchain cooperation projects with more than 40 major banks around the world , And Nasdaq took the lead in launching Ling, a securities trading platform based on blockchain technology. As a result, the blockchain quickly entered the people's eyes. As a result, the technology was also on fire.
Data Lake
Data Lake This technology is very hot in foreign countries, is a big data technology. Simple and plain speaking, the data lake contains the following two characteristics of the information system: First, you can save big data parallel system, and second, data can be calculated without moving the system. As big data continues to heat up, many people in the data center are constantly discussing and speculating around the concept of "Data Lake," whose value lies in bringing together different types of data, with the other part not requiring value Predefined models enable data analysis. Data Lake technology has a well-established architecture that works seamlessly with data science and low-cost, commercially-based machine learning analytics. Big data, data lake are data center computing tools to enhance the weapon.
Quantum communication
Data center security is getting more and more serious. People are generally worried about putting their own information into the data center or transferring information. The biggest feature of quantum communication is its security. In quantum cryptography (such as the BB84 protocol), it is due to the quantum non-clonality theorem that the state of polarization changes when the photon is intercepted and measured. The receiver will detect the password error, stop the password communication. This ensures the security of quantum cryptography when communicating, thus ensuring the security of encrypted information. The deployment of quantum communication technology in the data center will largely eliminate concerns about information security and promote the development of data centers.
Smart City
Smart city is not a new word, derived from the concept of "smart earth" put forward by IBM in 2008. In 2015, Premier Li Keqiang of the State Council pointed out in his report on the work of the Chinese government that for the first time at the national level, the idea of ​​vigorously developing smart cities will be put forward. As a result, smart city became a hot term in the field of technology in 2016. To many people, this tall topic seems unfamiliar and distant. Actually, the construction of smart city has already infiltrated our daily life through various ways of presentation and has changed many aspects of our life, such as smart home, smart wearable device and industrial 4.0. Smart cities actually use information and communication technologies to sense, analyze and integrate key information about the core urban operation system so as to make various demands including livelihood, environmental protection, public safety, urban services and industrial and commercial activities Smart response. Its essence is to make use of advanced information technology to realize the city's smart management and operation so as to create a better life for people in the city and promote the harmonious and sustainable growth of the city. Smart cities provide vast space for the development of data centers. If a city wants to be a smart city, it must rely on data centers to bring together various information and data through data centers and establish various application information systems to become smart cities.
2016 appeared a lot of popular technology, especially applied to the field of data centers, not all one by one in this inventory. In the field of data center technology, the phenomenon of "one hundred schools of thought contend and flourish" has emerged. All kinds of new technologies and new concepts are not poorly endowed. We must closely follow the trend of technological development, utilize advanced technologies to arm data centers and allow data centers to develop Better.
