【摘要】：为了对大规模的数据访问和海量海洋信息的处理提供可靠实时的云计算服务,结合工作流与软件即服务(software-as-a-service,SaaS)的思想,提出软件服务流的概念,并构建基于云平台的软件服务流体系结构的系统.服务流引擎在整个系统中处于底层,与Hadoop平台进行交互,运行自行设计的服务流解析与重组算法处理用户请求,并交付下层执行,且为上层提供资源表述性转移(representational state transfer,REST)架构风格的服务流监控和资源管理的透明接口,降低了开发的复杂性,提高系统的可伸缩性.用户能够通过Web端访问,定制个性化软件服务,并且能实时监控云平台.在该平台上,大规模数据访问、高并发以及高密度的访问也是一种常态.通过构建初步的原型系统,证明平台体系结构的可用性和高效性.
[Abstract]:In order to provide reliable and real-time cloud computing services for large-scale data access and massive ocean information processing, the concept of software service flow is proposed based on the ideas of workflow and software as a service (software-as-a-service,SaaS). And build the system of software service flow architecture based on cloud platform. The service flow engine is in the bottom layer of the whole system, interacts with the Hadoop platform, runs the self-designed service flow resolution and reorganization algorithm to process the user request, and delivers the lower level execution, and provides the resource statement transfer (representational state transfer, for the upper layer. REST) architecture style transparent interface of service flow monitoring and resource management reduces the complexity of development and improves the scalability of the system. Users can access through Web, customize personalized software services, and can monitor the cloud platform in real time. On this platform, large-scale data access, high-concurrency and high-density access are also normal. A preliminary prototype system is built to prove the usability and efficiency of the platform architecture.
