Research On Key Technologies Of Process Customized And Evolution Based On Paas Pattern

PaaS (Platform as a Service) is the operating environment, development environment platform resources as a service cloud computing service model. By PaaS services, ISV (software vendors) will follow the norms deployed to develop a good application delivery PaaS platform, become oriented multi-tenant SaaS applications. To this end, PaaS cloud computing platform has become a new era of software delivery, deployment and use of the supporting environment.PaaS platform, delivered a number of different tenant SaaS services, and these different SaaS services through synergistic combination into multiple new SaaS services. For a SaaS service, but also through business processes to achieve the tenants’ business needs customization. Therefore, process management platform in PaaS an important role. However, the current PaaS platform business process customization encountered many problems; the traditional business process management technology does not apply:First, the expansion of the tenants, tenant demand change, large-scale multi-tenant application mode, and this change will provide SaaS-based business process operations enormous workload. How PaaS platform, all tenants perceive platform customized business processes quickly and effectively in the original SaaS process, based on the multi-tenant business process customization, is currently an urgent problem. Secondly, when the co-occurrence of tenant demand changes, how PaaS mode evolution of the business process itself, in order to quickly meet the custom needs of tenants, reduce customization costs, improve the efficiency of customization is PaaS platform customized business processes need to be resolved.To solve these problems, this paper proposes PaaS mode process customization and self-evolution techniques, including:1. PaaS platform for customized business processes and business processes from the evolution of the problems faced by cloud-based PaaS models and supporting technologies, proposed a rule-based business rules PaaS platform (BPPaaS), the basic function is to provide a platform for business processes customization capabilities, the platform through the rules engine PaaS mode, business processes and business rules separation, when tenants need to customize the process, the rule engine by referring to the process model with a custom rule set match, you can achieve tenant personalized configuration process. In addition to some notable features beyond the platform is the ability to customize information to tenants’ self-realization process model evolution.2. The demand for large-scale tenants frequently change, frequent changes in tenant demand for the issue, proposed a rule-based process model defined reference method, the tenant may customize the process according to their needs, the system is running stage, the rule engine by referring to the process models and custom rule set matches tenants processes to achieve personalized configuration.3. For tenant demand co-occurrence of change, the reference process model to modify the rule a lot of growth, how PaaS mode business process itself evolved to quickly meet the tenant’s custom needs, shorten custom cost problem, a PaaS mode processes and acting algorithm, to achieve the reference process model to modify itself to adapt to changes in tenants.Through the development of experimental systems for the above method was validated based PaaS platform, able to perceive all tenants customized business process models, business processes through the PaaS platform evolution itself, improve the tenants’ business process automation and custom tailored efficiency.
