Research And Practice Of Cloud Application Development Framework And Cloud Service Recommend Strategy

Cloud computing is evolving at rapid pace, cloud application are used on a large scale, service development has put forward higher requirements. However, the development of basic functional components and interfaces of cloud applications now rely on low cloud platform provider, the development efficiency, cannot meet the requirements of a variety of cloud application demand. In response to this situation, we propose a service-oriented, component-based cloud application development framework for service-oriented approach to provide services. The development framework includes cloud source layer, metadata layer, cloud service layer, operation control layer and application interaction layer. Each layer work independently and communicate by APIs. The cloud service layer makes the resource services, including atomic service and composite service.Services need common descriptive language and measuring standard, define the service descriptive language of ontology. Analysis the relation of service from descriptive language, combine with the reliability, efficiency and load of instance, put forward a cloud service recommend strategy by service weight and verify it by data simulation. Finally use the cloud application development framework and cloud service recommend strategy in the development of virtual laboratory system, improving the development efficiency and operate in real teaching situation stability.
