The application of SOA and cloud computing in intelligent cities

Recently, the Four China SOA Standardization Symposium was successfully convened, and the meeting came from various industry experts, users, government and other related personnel, and discussed the SOA standards and development. The following is the China Digital Government Strategy Headquarters consulting director Zhang Penghua on SOA and cloud computing in the intelligent city of the application of a detailed introduction.

Now this globalization, the trend of marketization, urbanization and informatization is unstoppable, and the Twelve-Five planning countries also put forward the integration of urbanization, informatization, including the new tri-fusion of industrialization which we say, in fact, this reveals that our urbanization should be the most important driving force for our Chinese economic development in the next 10 to 20 years. In this development process, in fact, the next 15 years we have data statistics, there are nearly 3 to 400 million people into the city, these millions of cities in the country reached 221, and now such cities in Europe only 35, in such a large-scale migration and urbanization of the construction, These cities are facing new headaches.

They need to build more than 5 billion square meters of road, building a total construction area of up to 40 billion square meters of buildings, such a process of urbanization brings many problems, including population expansion, traffic congestion, environmental pollution, we analyze the root causes of such problems are from the lack of public service resources, These need the government to set up a new generation of management government and service-oriented government, and based on our new management platform, we believe that in today's information should become the development of micro-urban civilization, a novel link and an important link. And the integration of city and information, the depth of integration, can help the city to improve efficiency, can make the world happy. We believe that today's information, urban management should need the most advanced management concepts, these advanced management concepts, in fact, the most need is advanced technology and support, which we say the standard of this construction, especially the construction of intelligent city.

And this kind of informationization and the construction of urbanization, inseparable from cloud computing and cloud service support. We say that cloud computing is the most important aspect of application that supports us in terms of technology, standards, or SOA. So based on the above analysis and our accumulation, we build our Intelligent City 3.0 architecture, in the following communication and information infrastructure, we will use cloud computing technology will be the city-level resources, computing resources, storage resources, related resources to integrate, unified scheduling, management and operation. Information Resources and service Exchange system at this level, we will take advantage of the relevant technologies of SOA, we say, in various areas of population information, corporate information, geographic information to do some application to get through, to prevent them from fragmentation, the formation of their interconnection and interoperability situation. In the application service level, in fact, for the public can be seen, for the enterprise management, the city for us to talk about the administration and operation, then we will be integrated application of SOA to do cloud computing technology, with SOA solution? Solve the loose coupling between applications, service problems.

Using cloud computing to further solve the problem of the unified delivery operation of the service layer in the application layer, the rapid extension. Based on such a city structure, we actually have the ability to build a smart city in our company. Can also help, we can see the establishment of a happy city, the establishment of a prosperous city, the establishment of a harmonious city. Based on this strategy, digital China has been in the country for several years, we are in the second-line three districts, Beijing-Shanghai, Beijing-Guangzhou, two lines and so on three areas to do a lot of projects, through these projects we have some more or less SOA application experience, these experiences in chapter two we introduce to you how we use SOA, how to use cloud computing, How to build a technical framework to solve real life problems.

First of all, in many of our cities, in Guangzhou, in Foshan, in Wuhan and other cities, the construction of the city of Wisdom we said the comprehensive service application scene, the goal is to provide the public with this convenience of the general people of the comprehensive services, such as our Beijing lottery car, such as traffic card, with financial functions. For example, to apply for credit, these businesses have a feature that they all have to go through N departments, including what? including transportation, civil affairs, housing management, social security, taxation, even education, etc., and so on, different kinds of business openings and application systems. In this process, there are many problems, such as what the public and the public, including enterprises, enjoy. Enjoy the channel is not smooth, the service is not standardized, not uniform, quality under, do one thing to run a number of places, to fill out a table of information, this in our implementation of the construction process we use SOA technology and standards, Under the standards of the unified standard system, you can see that in the unified standard system, the government's business systems, such as social security, civil affairs, public security, the community of these systems to carry out the service function of the encapsulation, finish the encapsulation, as a provider to ensure the good availability of services, and provide a wealth of business use resources, and supported by this SOA technology platform, it is possible to implement the on-demand functions of government departments loosely coupled. Effective formation of collaborative services, integrated services for the entire scene to provide technical support.

In fact, when the public, what we are talking about in this scenario, when the people need more? Anytime, through various channels, want to get this information, SOA is not enough, need some features and support of cloud computing, In this process we understand that there will be cloud computing in such a scenario and then just the construction of the project on the basis of the cloud to achieve all of this computing resources, storage resources and all the scheduling, cloud computing can enjoy this service through various terminals. We are not only facing these problems in the process of building this intelligent city.

We understand such a technology or model of cloud computing, it should be said, throughout the entire we said in the service of the people, business managers, services at all levels of users at every level of the overall demand. First of all, you see this is the basic level of urban information construction, in order to solve the network storage and computing capacity of the unified management, we need to establish a city-level infrastructure cloud, these clouds should focus on the application of virtualization or pool management technology.

Immediately following should be the service equipment, or we call the service facility angle, in the middle we say is the service matter, the service business angle, in this business application level, in order to solve a certain industry specific problem, or their this particular industry centralized management question, the problem of On demand, the flexible dispatch question, We need to build the city-level application services cloud, including what medical cloud, education cloud, tourism cloud and so on, what these clouds need is rapid extension, maintain the high reliability and continuity of the business and so on.

Of course there is a higher level, for example, we in the public service level to solve the business and the public, to have this kind of comprehensive services, we also need to build a city-level integrated services cloud, including our often mentioned people's livelihood cloud, corporate public service cloud, These are built on the basis of this support cloud based on our infrastructure and the concentration of resources in a particular application area just now.

The current SOA should be one of the mainstream technologies that cloud computing provides ubiquitous unified services and unified access. But cloud computing can fully meet the needs of end users at all levels through SOA's uniform and standardized service resources. So based on the above understanding, we build a whole set of cloud computing architectures based on the entire intelligent city and the needs of the entire intelligent city. In this framework, we should see that there are three parts. On the left is the standard specification system, which includes a standard system for SOA, as well as some cloud computing systems. We have focused on this management of our upcoming Web services in concrete practice, including this overall technical requirements, such as the requirements, to achieve some, to ensure that the system loose coupling, including the service of encapsulation, we have been supported by the standardization of some guidance and help. The second part of the middle is the most typical cloud architecture, SAAS, AAAS, IaaS architecture. First we look at IaaS, which includes unified management, asset management, and extensible self-service portals. PAAs includes cloud computing middleware, test architecture, deployment architecture, configurable, manageable architecture. We focus on the SaaS architecture, and the relationship between cloud computing and SOA should be understood at this level, and is the most tightly integrated. SOA should be said to play a fundamental supporting role primarily at the SaaS level, where SOA is the foundation of the service encapsulation standards throughout the cloud's SaaS structure. In order to be able to meet the leasing, chargeable operations we have said, we should provide some application patterns that apply to software operations. If you're going to have to use multiple channels to support this feature, then SaaS is not enough, and you need support from cloud computing middleware or cloud computing platforms.

In particular, our Working Group on SOA standards, the system should be well established, the relevant standards are being developed, we have a more mature understanding of them, in fact, we think that SOA as a means of supporting cloud computing in the future, not simply to encapsulate the business into services, It is impossible to throw the service into the cloud environment. This situation requires us to further the characteristics of the cloud, based on our existing software technology resources, how to study, can get some of the technology and standards used in the cloud environment, so we also recommend that colleagues, under the leadership of our working group, we can study some of these standards, this is how SOA can be encapsulated, It is easy to transition to the cloud computing environment and to support the associated cloud computing features. In general, such a system in the technical framework, should meet the overall wisdom of urban information construction of some of the main problems and this demand. Then we will share a case with you, the case is we said, just mentioned the wisdom of Foshan.

Foshan is a place less than 4,000 square kilometers, the city now resident population how many? More than 7 million, floating population more than 4 million, the congestion of this population brings enormous pressure to the government, but also brings many problems. In fact, Foshan is determined to use the means of information to solve and alleviate some problems. So we help them to do some planning and implementation, you can see that this is a whole set of wisdom Foshan Public service architecture and the overall plan schematic. From this picture should be seen, this picture and we just introduced the overall cloud computing architecture is consistent, the left is the technical standards, the middle is operational support, the right is the embodiment of technology. The bottom line is service providers, government departments, community departments, etc., which provide a variety of resources, including business service resources and data service resources. For example, there are government-provided intelligent transportation, including civil service, the business sector also provides some electronic payment, express logistics services. Because they belong to different departments, in order for them to standardize, the standard of unification, we have applied the relevant technology of SOA, they form such a set of service resources. Service has, how to better apply these services, how to be very effective, anytime to get the public access to this service, we are in the implementation of further building above the public integrated services cloud platform, through this platform to extract the following services, so that it has the characteristics of the cloud, through a variety of channels to serve our upper level of our users, and the public.

In fact, for example, resident residents can access some services of their own concern through various channels of personal Terminal Services, television, mobile phones, computers and other channels. This temporary resident and the floating population can through the community service station, can complete the related administrative class insurance transfer, the floating population registration and so on business, the administrative business support. Through the real landing and implementation of the wisdom of Foshan, we really do have a little experience of SOA and cloud computing, and we feel that as a standard system that supports SOA and cloud computing, it should become more and more important and more effective in future smart city construction.

In fact, we think that the first in a city in the construction of information, through the standards of SOA can support what? Support the integration of effective different business areas, we say to interconnection, on the one hand, through the cloud computing standards of communication, to achieve the overall urban resources intensive management, including automatic deployment and so on this aspect content.

On the other hand, the Government can provide various services to the urban chain on such a basis. We are based on standardization, there is also a second benefit, the first advantage is built in a city, the second advantage is that we will be in this standard of intelligent city building experience and results quickly replicated to the next city, so what is the benefit? This can help the governments and leaders of other cities, Conditional quick Reference and some use of other city management model, can also bring us more benefits.

Further said that, based on standardization, we will be possible to achieve in the future with this urbanization of the in-depth integration of information, we should be able to realize the interconnection of intelligent cities, the interconnection of urban construction, the formation of our so-called intelligent city, the wisdom of urban agglomeration, intelligent City Circle, wisdom China such effect. We have the need, the will, and the motivation to study the application standards of SOA cloud computing under the leadership of the SOA standards team, as well as the advantages of our digital China in the country, to help our entire standard system landing and rapid validation and promotion. The goal of our smarter City is achieved through standardization, and it should be said that, under the leadership of the SOA portfolio, some small business goals can be achieved.
