Cloud computing is the wings of Smart city development

The pace of urbanization is getting faster. According to statistics, 70% of the population will live in the city in 2050. Cities are growing, populations are exploding, traffic is deteriorating, pollution is severe, energy consumption is staggering, medical resources are scarce and living costs are rising. A collection of multiple applications, for many industries, a systematic platform is ready to resolve the contradictions between resources and needs, this is the concept of intelligent city.

Intelligent City is an innovative urban environment form under the support of new generation information technology. The core concept of intelligent city, on the one hand, is people-oriented, on the other hand, constant innovation. The construction plan of intelligent city is to integrate urban resources and to carry out perceptual interconnection and collaborative processing with highly efficient and intelligent systems. Facing the contradiction between system complexity and limited computational resources, cloud computing came into being in the tide of Informatization, and became a necessary way to build Intelligent City data center.

In recent years, as a new industry revolution, the essence of its service is to provide the customer with autonomous service based on the network's service supply model supporting heterogeneous facilities and resource flow. Cloud computing to the resources on demand, according to the amount of billing, is conducive to reducing investment costs, improve resource utilization and information operation efficiency. Smart city construction and cloud computing development complement each other, the idea of smart city will push cloud computing mechanism to the ground, on the contrary, cloud computing's Super computing power will also put the urbanization process "wisdom" wings.

The construction of Intelligent city, the core of cloud computing data center, to build a platform independent of a number of applications, such as municipal cloud, traffic cloud, education cloud, security cloud, logistics cloud, medical cloud, etc., for all types of upper application support, this series of cities in all walks of life information platform collectively known as the "Wisdom of the city cloud."

Based on the wisdom of cloud computing, the technology architecture is divided into four layers, which are the perceptual layer, the network layer, the platform layer and the application layer, and the four layers realize the complete interconnection and interoperability.

The perceptual layer deploys a series of digital terminals, including PCs, mobile phones, cameras, sensor networks, call centers, and so on, to fully perceive the external environment and respond to the surface phenomenon in the first time.

Network layer through a variety of network equipment, networks (including the Internet, mobile networks, IoT) and the perception layer of various devices to connect, the equipment to obtain real-time transmission of information to the business platform, to achieve the interconnection between the architecture layer, for the interoperability of the business lay the foundation.

The platform layer designs a unified platform through Operation management, solves the problem of business and resource operation management at the business level, solves the abstraction of network and the management of resources at the network level. The platform is based on cloud computing data Center, integrates resources with virtualization technology, develops and constructs a series of intelligent city business cloud platform. Smart city data centers to conserve footprint, reduce energy waste and improve operational efficiency for the purpose of the choice of infrastructure to consider high-density low-power servers, such as the recent introduction of the First China cloud computing conference by the Nanjing Cloud Chong Storage Technology Co., Ltd., Intel, China Electronics Technology Group 32nd Research Institute jointly developed the world's first largest capacity PB-class cloud storage System----based on the IA architecture of cloud storage integrated machine, with its 3 times times Energy saving, 5 times times capacity, 10 times times cost-effective, breakthrough the density cloud storage products limit, fully meet the PB-level cost-effective server deployment needs.

The application layer uses the data obtained by the perceptual layer to construct the corresponding business system, utilizes the data storage and processing capabilities based on cloud computing, develops the urban application of different industry fields, realizes the intelligent service of various industries and industries. such as in the wisdom of urban management cloud, to Cstor cloud storage system as the infrastructure, integrated cvideo cloud video surveillance system. The integrated scheduling and cloud transcoding can meet the requirements of super large scale HD video surveillance, massive data storage, and long-distance monitoring. At the same time, the early warning system built on the monitoring platform will exchange information with the data center of the Ministry of Public Security, timely reflect the emergency situation, shorten the crisis response time and improve the safety protection efficiency. In the aspect of video content, combined with large-scale distributed cproc cloud processing for intelligent image recognition, the second-level integration and index of massive video data are analyzed to help police solve cases.

The Intelligent City Cloud construction takes the best plan to make the citizen enjoy the most efficient information resources service, promotes the modern service industry to develop healthily and rapidly. Cloud computing Centers can aggregate multiple application platforms and dig deeper into the data to provide a better platform for government decisions, corporate development, and public services. Through its load balancing mechanism, it can improve the utilization of it physical resources, reduce the cost of equipment investment and reduce the waste of energy. Its centralized management of resources can save human resources expenses and reduce maintenance costs. In the efficient flow of resources, the information threshold is reduced and the process is bound to accelerate.

Intelligent city is the inevitable result of the development of urbanization, and cloud computing, as the fourth information technology revolution in the industry, is bound to occupy an important place in the urban informatization layout. With the "Twelve-Five" planning of the Internet, provinces and cities have launched an intensive intelligent city planning and implementation. In the innovation-driven, people-oriented purposes, the use of cloud computing to build a systematic platform for urban development, promoting the interconnection, advanced, systematic, our city will be full of "wisdom."
