The Design And Implementation Of Paas Platform For Integrated Information Services

In recent years, with the gradual deepening of IP-based telecommunications networks, telecommunications services, especially information service presented diverse and complex trends. The building of telecommunications information services platform draws more and more attention of the operators. How to build the information service platform which is adapt to the development demand, has become an important factor affecting operator service development and core competitiveness.The appearance of Integrated Information Service Platform solves the following issues exsisting in the traditional information service platform:The high access threshold of service capabilities; The duplication building of functions and hardwares; scattered data and resources. It shields the heterogeneity of the underlying network, supporting the open of a variety of information services capabilities and providing a wealth of information services for SP, reducing the investing and operating costs of service development and maintenance. But there are also some shortcomings as to the integrated information service platform:1) a higher threshold for service development;2) the lack of appropriate resources strategy to allocate the resources according to need;3) poor extensibility and scalability, low resources utilization rate.In order to solve the above problems exist in Integrated Information Service Platform, a PaaS platform for Integrated Information Services is proposed in this paper. The platform can integrate a variety of telecommunications capacity and open these to SP with unified APIs. The platform supports the development of customized information services and provides an environment to deploy. It reduces the difficulty of service development with a templated service development approach. It also improves the efficiency of service development. This platform supports DAMA(distribution according to need) of system resources. In addition, PaaS platform for integrated information service has good scalability and flexibility based on the unlimited scalable virtualized resource pools of infrastructure layer(IaaS).Based on the research of cloud computing technology, this paper analyses the design and implementation of PaaS platform, mainly from the following aspects:demand analysis, design and implementation of the platform, the test and application deployment. The main contents include:the background of integrated information services platform, cloud computing and PaaS platform is introduced firstly; Then the requirement of PaaS cloud services platform is analyzed from two perspects:functional and non-functional requirement; the static logical structure and dynamic processes maps of PaaS cloud services platform are described in the core part of the paper, as well as the detailed design and implementation of two main modules; Finally the test procedure is described in the test part, and gives the prospect for the development of the platform.
