The word "cloud" has repeatedly appeared in the recent security industry. Words such as cloud computing, cloud storage, and cloud services have become popular, which should be attributed to the development of Internet mobile technology. The application of cloud technology in monitoring, access control, intelligent transportation, smart cities, smart homes, etc. is also the official mainstream. Cloud storage Monitoring data cloud storage The development of security monitoring technology has gone through three phases: simulation, digitization and networking. The emergence of network monitoring solves the traditional problems of monitoring remote transmission effects, and also changes the traditional connection methods, making it simpler and more convenient, but at the same time it leads to larger storage requirements and higher bandwidth requirements. Correspondingly, monitoring data storage has also undergone multiple stages: analog data storage, digital storage, and centralized network storage, and it has evolved into cloud storage. Monitoring the emergence of cloud storage, breaking through the performance and capacity bottlenecks of traditional storage methods, enabling cloud storage providers to connect a large number of different types of storage devices in the network to form exceptionally powerful storage capabilities, enabling linear expansion of performance and capacity. Mass data storage becomes possible. Cloud storage technology is an important means to break through the bottleneck of IP high-definition monitoring storage. Cloud storage technology has a huge application prospect in the development of security monitoring industry. The traditional security industry believes that video loss is a device problem, but in fact it is more about system solutions and storage technology issues. Cloud storage can provide high-reliability, high-performance, low-cost security systems, deployment on demand, and flexible expansion. In the Internet age, the greatest advantage of cloud storage is its openness. However, to solve security problems and adopt encryption, system hardening, and authentication access, data protection can be strengthened. In view of the current strong domestic cities that are strongly promoted, and financial applications that require a great deal of security, all require higher reliability and safer data storage solutions. Today's security equipment suppliers should actively develop advanced storage solutions. cloud computing Intelligent Transportation Relies on Cloud Computing "Cloud Computing" originated in the IT field. Today, with the increasing IT of intelligent transportation, the "cloud computing" application in the intelligent transportation field is also widely expected in the industry. "Cloud computing" is defined as a model based on the delivery and use of network services. People obtain the required services through the network on demand and in an easily expandable manner. Such services can be either Internet-related software services or other services. The network that provides the resources is called the "cloud." It can automatically split the huge calculation processing program into numerous subroutines through the network, and then submit it to a huge system composed of multiple servers. After the calculation and analysis, the processing results are passed back to the user. Through "cloud computing" technology, network service providers can process tens of millions or even billions of information in seconds, and achieve the same powerful network services as "supercomputers." These characteristics exactly coincide with the functional requirements of intelligent transportation services with “highway number, high-definition, and intelligentâ€. First of all, the intelligent traffic service must provide comprehensive road conditions and realize comprehensive monitoring of urban road traffic conditions, traffic flow information, and traffic violations, especially during the peak traffic period. It needs to collect, process, and analyze large amounts of real-time monitoring data. Secondly, the timeliness of the release of intelligent transportation service information is very demanding, and accurate information needs to be sent to the main subject of different needs in a timely manner. In addition, intelligent traffic service systems need to have high reliability and stability. Cloud computing becomes the core power of smart home With the improvement of living standards, sales of smart homes are getting bigger and bigger. How to connect more than a dozen smart home devices in the home or connect new ones together becomes a new problem. The massive data brought by the cloud computing-supported computing infrastructure lays the foundation for solving these problems, and it will surely become the core driving force for smarter home applications. In recent years, the development trend in the field of smart home, in addition to some of the existing lighting control, infrared control, curtain control, remote control and other related technologies, in particular the more widely used applications of IoT sensing technology and identification technology represented by RFid, Create the smart means people need. The essence of smart homes is to facilitate people's lives. All of these things require people to control, but at the same time they must also improve intelligence and reduce the inconvenience of people to control. So in the age of smart homes, cloud computing technology will become an important support. The back-end services of technical network systems require a large amount of computing and storage resources, such as video websites, photo websites, and more portal websites. With the high degree of development and application of the Internet of Things industry, each item in the future may have its own identification mark, which needs to be transmitted to the back-end system for logic processing. Different levels of data and various types of industry data require strong system backing support. Smart is achieved through cloud computing. Combine all computing resources and storage resources that can be integrated through cloud computing to jointly process requests for global smart home business, and flexibly expand corresponding computing and storage resources through on-demand use, and integrate IoT resources as the smart home field. Important support platform. cloud service Smart City Construction Cloud Service Fueling In the second round of implementation of the smart city project, the industry boom remained high. Under the premise of a good industry, security industry presents three major trends: high-definition, smart, and network. Under the influence of networking, cloud storage and cloud computing have emerged, and cloud services will also become the next industry hot spot. The promotion brought by cloud computing to security is enormous. With the development of cloud computing and big data in recent years, the storage and intelligent analysis problems in video surveillance services have been solved, and the role of technology promotion is very obvious. This is due to the increasing popularity of video surveillance in security, transportation, medical, and logistics applications. Massive video processing requires a corresponding storage and computing platform. The three levels of the Internet of Things are sensor monitoring, network, and applications. In the future, video surveillance is an extremely important core node of the Internet of Things. The amount of video information is huge. With the expansion of the global eye scale and the development of high-definition, the massive transmission and storage needs will require more cloud storage, cloud computing, and cloud search technologies, as well as large-scale networking applications. Therefore, providing enterprises with a system of cloud services or another business will open the door. In the “cloud era†development trend, various types of data through cloud storage are solutions, but advanced learning and preparation are also required before the data center is established and used. Attachment: Concept brief Cloud computing is an increase, use, and delivery model of Internet-related services, and typically involves the provision of dynamically scalable and often virtualized resources over the Internet. Cloud storage is a new concept that has been extended and developed in the concept of cloud computing. It refers to the adoption of cluster applications, grid technologies, or distributed file system functions to transfer a large number of different types of storage devices in a network through application software collections. A system that works together to provide external data storage and service access capabilities. The business model of cloud services is to provide a wealth of personalized products by breeding a large number of startup companies to meet the growing demand for personalized personalization in the market. Its breeding method is to provide start-up companies with funds, promotion, payment, logistics, and customer service as a whole set of services, and to use their operational capabilities like water and electricity for external use on demand. 1.HSK FMA Face Milling Arbors Cnc Milling Tool Holders , used in the clamping of the cutter with the radial drive groove, such as the face milling cutter, the vertical disc cutter, the set type end mill, high speed and high precision machining .Mechanical spindle and cutting tools and other accessories.High Precision HSK shank Tool Holder ,balanced G6.3 or G2.5 For choose.
