Research And Design Of PaaS Platform For Oil And Gas Production Integrated System

Rapid spread of mobile internet not only triggers the fast development of various intelligent terminals,but also prospers the application market.The traditional application delivery mode can not achieve the stable operation of application and the rubber-sheeting of load capacity under the high stability of the application.And the PaaS technology based on cloud computing can meet this demand to provide a stable,reliable and elastic operating environment for all types of applications.As a result,application developers can focus on the achievement of the business logic for application itself to achieve faster application development,reduce the complexity of operation and maintenance and improve resource utilization.Building enterprise private cloud PaaS platform based on open source technology to achieve the reliable delivery of application has become the mainstream model of application development for mobile Internet.Some enterprises,such as oil and gas companies,should follow the trend to build their own private cloud platform.According to the basic needs of application development for oil and gas enterprises in the era of mobile Internet,firstly,based on the open source technology,this paper researches on building the overall architecture and service mode of enterprise private cloud service platform which is as a core with PaaS.Based on Open Stack virtualization technology and open source cloud platform Cloud Foundry,a private cloud PaaS platform solution for oil and gas enterprises is designed.On this basis,a stable and flexible private cloud PaaS platform environment can be built.Secondly,for the elastic drawback of the application access request scheduling and platform in the application of access request scheduling and application load capacity for platform,through the real-time calculation of application examples and the running node load status,the platform application access request is realized according to dynamic scheduling of instance load conditions and application examples in accordance with the rubber-sheeting of accessing the load.Finally,as for the extended function requirement of cloud platform,this paper studies the extension technology about database basic service.Based on the study of the extension method about cloud platform service,the extended structure and logical architecture of Service basic service are designed according to the composition of Service and its working mechanism,Service Node and Service Gateway.In conclusion,based on the open source platform Cloud Foundry,this thesis designs a set of private cloud PaaS platform for oil and gas enterprises,which uses the hierarchical load adaptive PaaS platform application to access request scheduling strategy in order to improve the flaws in the platform request scheduling,and achieves the load balancing of platform application and instance elasticity.On this basis,a highly efficient and stable private cloud PaaS platform can be built.
