Application of cloud computing in chemical industry

1 Introduction

The necessity of application of 1.1 cloud computing in the construction of chemical enterprise informatization

Cloud computing is a highly scalable and manageable system pool capable of computing infrastructure for end-user applications, parallel computing (Parallel Computing), distributed Computing (distributed Computing) and Grid computing (grid The development of Computing, or the commercial realization of these computer science concepts.

Cloud computing is the result of a mixture of concepts such as virtualization (virtualization), Utility Computing (Utility Computing), IaaS (infrastructure as a service), PaaS (Platform-as-service), SaaS (software as a service), and a leap in this way, Shared hardware and software resources and information, such as networks, servers, storage devices, applications, and services, can be provided on demand to computers and other devices.

In the petrochemical field, cloud computing can achieve reasonable allocation of resources and improve utilization rate by computing the virtualization organization, distribution and usage pattern of resources. Chemical process simulation and simulation, molecular simulation design processes require a large number of complex calculations, cloud computing can provide a shared platform for computing resources, the entire process will become more simple and efficient, thus avoiding the duplication of the calculation process and waste of resources.

The information system of petrochemical enterprises needs to calculate more and more data of production and operation. These data are from the Process Control system, MES (production execution System), LIMS (Laboratory information Management System), SRM (procurement Management), ERP (Enterprise resource Planning), CRM (Customer Relationship Management), SCM (supply chain management), office automation, process simulation optimization system, Implement integration and data analysis applications through centralized databases or SOA (service based architectures) and portal technologies. With the development of business, the cost of data analysis is more and more big. Therefore, the enterprise is very eager to have a shared data platform to provide production and management solutions.

The advantage of using cloud service mode in Enterprise management software is: No need to be equipped with IT professional and technical personnel, at the same time can get the latest technology applications to meet the enterprise information management needs. Only relatively inexpensive "monthly" mode of investment, not one-time investment in place, do not occupy too much of the operating capital, thereby alleviating the financial pressure of enterprises, do not consider the cost of depreciation, and timely access to the latest hardware platform and the best solution. Do not need specialized software development maintenance and management personnel, to a large extent, to ease the enterprise in the human and financial pressure, so that it can concentrate on the core business of funds to operate effectively.

1.2 The present situation of informatization construction of chemical enterprises

Petroleum and chemical industry is one of the earliest applications of information technology, from the earliest single-chip, engineering design and other software simple application of efficient and complex system on-line, the application of industry information gradually in-depth. After several years of development, industry informatization from concept to application, from blind to rational, experienced a complex and full of controversy, during the process of information construction, many enterprises due to lack of understanding of information caused the waste of funds and resources.

In recent years, the informatization of petroleum and chemical Enterprises has gradually entered the stage of rational development. At present, the production process of industry enterprises has basically realized automation, which reduces the cost of production operation. Due to a large number of chemical enterprises production equipment, and most enterprises are cross-regional production, production equipment management is difficult, in the early stage of industry information development, due to the lack of information awareness, the relevance of the system to understand not enough information construction, resulting in the interconnection between the system can not be interconnected, information isolated island phenomenon is serious, Hindered the process of industry informatization.

In the process of the current informatization, the application of information is developing rapidly, and a large number of data should be analyzed, data mining and multivariate analysis so as to find the relation of data, and bring a lot of calculation and storage demand. And meet these needs only by the enterprise's own construction is very unreasonable, because the demand is not fixed, to pay high costs outweigh the cost, therefore, the information construction urgently needs a supporting platform.

2 Development of chemical enterprises to the demand of informatization

As one of the basic industries of China's national economy, chemical enterprises have played an important role in promoting economic development and meeting the daily needs of the masses. With the rapid development of science and technology and the intensification of international competition, our traditional chemical enterprises are confronted with new challenges, how to effectively transform production links, strengthen enterprise management, improve production efficiency has become a problem that many enterprises must face, enterprises through the integration of various information in the supply chain can be from procurement, inventory, After-sales service to improve the production efficiency of enterprises, to make timely control of the productive chain; Through information management enterprises can obtain the latest technology research and development information, timely determination of the company's technology production direction, thereby improving their own production efficiency; Through information management, enterprise decision-makers are able to know all the information in time, At the same time, information management can guarantee the authenticity and timeliness, and create favorable conditions for decision makers.

In the past, the low price of labor, crude oil, coal, electricity, land and other resource factors condoned the extensive model of high energy consumption and low value-added of chemical enterprises, which hindered enterprises and industries from enhancing their competitiveness by improving technology and efficiency, forming their own brand and self-innovation ability, Moreover, the contradiction between the pollution caused by energy consumption and the limited capacity of ecological environment is becoming more and more prominent, the resource environment cost of production growth is very high, and energy saving and environmental protection work. To continuously improve the value-added of products is an important strategy to improve the company's income, and the current global competition is increasingly fierce, the most important way to achieve high value-added is innovation, informatization is an important part of enterprise management innovation, so the use of computer software system to achieve comprehensive information becomes an inevitable trend.

3 The concrete deployment of cloud computing in the informatization of chemical enterprise

Building cloud computing platform to improve system portability and to take full advantage of more optimized system and network resources to improve efficiency and reduce overall cost is a key problem to be solved. To this end, we take chemical enterprise related application system as the top-level structure, build data center cloud computing resource pool. It is composed of computing resource pool, storage resource pool, network resource pool, chemical related business application software system and operation management platform, and the Operation Management platform is responsible for management scheduling and alarm monitoring of resource pool and application. The composition framework is shown in Figure 1.

Figure 1 Data Center cloud computing resource Pool composition Framework

Cloud computing platform service side of the complexity and innovation, for the operation of the dimension is a new challenge, operation and maintenance of ideas and ways to change accordingly. In the construction of cloud computing platform, a set of computing operation and maintenance platform is built to realize manual and automatic operation and maintenance. To build a cloud computing platform, we first need to set up a complete pool of resources (network resource pool, computing resource pool, storage resource pool), and the management of these resources, the cluster is the basic operation unit, from the original server as a basic operation unit, into a cluster as the basic Operation unit. Cluster capacity management, deployment, monitoring, fault management and other operational tasks, must be clustered as a unit. Cluster mobility dimension includes the implementation of efficient and large-scale deployment, upgrade, migration, expansion and fault management and other operational tasks.

Based on the computing resource pool, storage resource pool and network resource pool, the IaaS cloud Platform is built to provide services for the information construction of chemical enterprises, and the chemical enterprise can deploy and run any software, including operating system and application. Chemical enterprises do not manage or control any cloud computing infrastructure, but can control the choice of operating system, storage space, deployment of the application, but also may have limited network components (such as firewalls, load balancer, etc.) control.

Along with the development of cloud platform, based on the IaaS construction, we set up the PAAs service mode, and use the Software development platform (or business base platform) as a service and submit it to the chemical enterprise users in SaaS mode. For the enterprise to provide customized research and development of the middleware platform, while covering the database and application server. PAAs can increase the amount of resources that are utilized on the Web platform. Using data as a service (Data-as-a-service) through a remote Web service, you can also use a visual API and even allow you to mix and match other platforms that fit the user's application. A chemical enterprise or software vendor can quickly develop the applications and products it needs based on the PAAs platform.

With the development of cloud computing platform, each chemical enterprise should adopt SOA architecture concept, use the process and data interaction ability provided by ESR (Enterprise Service Bus), and provide data access interface for future applications and business software through the interface of Web service such as XML. This is because the traditional architecture package is a stand-alone software that integrates many application functions together in a complete package. An SOA architecture allows individual application functionality to be separated from each other so that they can be used individually as a single application feature or as a "component." These components can be used to create various other applications within the enterprise.

4 Conclusion

Cloud computing is generally considered a business computing model. It distributes computing tasks on a pool of resources composed of a large number of computers, and can obtain computational storage space and information services on demand. Cloud computing is not only a computational problem, it needs to integrate many technologies and achievements, the application of cloud computing technology in the information construction of chemical enterprise is significant and far-reaching.
