【摘要】：在未来网络的研究过程中,科研人员往往会面临实验环境搭建困难,规模太小,工具无法迁移等问题。服务创新平台解决了这一系列问题,向科研人员提供了一个统一的,共享型,一站式服务云平台。该平台是基于OpenStack的Icehouse版本搭建的私有云,只提供基础设施即服务(IaaS)层面的服务。目前,越来越多用户需要使用基于平台即服务(PaaS)和软件即服务(SaaS)层面的应用服务,而应用服务又需要独立的数据库即服务做底层支撑,同时平台OpenStack的Icehouse版本中数据库即服务组件Trove存在很大局限性。因此,本文独立设计并实现了服务创新平台的数据库服务与应用服务。首先,本文设计实现了共享型MySQL数据库服务。服务以MySQL作为底层数据库,满足了绝大部分平台用户对数据库类型的需求;该服务能够保证多租户模式下,用户资源的有效隔离,同时还能最大化平台资源利用率;服务具有独立的容量监控系统,可以实时显示用户数据容量占用和限制数据容量大小;数据库服务具有良好的伸缩特性,也能够兼容OpenStack的Trove组件。然后,本文通过使用Docker容器技术,设计并实现了一套符合平台用户习惯的应用解决方案。服务使用平台提供的虚拟机,作为应用容器的宿主机,保证了平台的统一化管理,合理利用了 OpenStack的功能机制与Docker容器优势;服务实现了简单应用的负载均衡,并以设置宿主机资源池的方式,平衡资源占用;同时,服务结合了平台集成的代码测试工具,提供了完善的代码上传,测试和部署机制。最后,本文通过实验,测试了数据库服务与应用服务的功能特性与响应能力。结果表明,用户能够通过服务创新平台统一的Web界面,直接使用数据库服务与应用服务,功能设计符合实际,达到预期。
[Abstract]:In the future network research process, researchers will often face the difficulties of setting up the experimental environment, the scale is too small, tools can not be migrated and so on. The service innovation platform solves this series of problems and provides a unified, shared, one-stop service cloud platform for researchers. The platform is a private cloud based on the OpenStack version of Icehouse, providing infrastructure as a service (IaaS) level only. At present, more and more users need to use platform as a Service (PaaS) and Software as a Service (SaaS) level of application services, and application services need independent database as services as the underlying support. At the same time the platform OpenStack's Icehouse version of the database as a service component Trove has great limitations. Therefore, this paper independently designs and implements the database service and application service of service innovation platform. Firstly, the shared MySQL database service is designed and implemented in this paper. The service takes MySQL as the underlying database to meet the needs of the majority of platform users for the database type, this service can ensure the effective isolation of user resources in multi-tenant mode, and at the same time maximize the utilization of platform resources. The service has an independent capacity monitoring system, which can display user data capacity in real time and limit the size of data capacity. Database service has good scalability and can also be compatible with the Trove component of OpenStack. Then, by using Docker container technology, this paper designs and implements a set of application solutions that conform to platform users' habits. The virtual machine provided by the platform is used by the service as the host of the application container, which ensures the unified management of the platform, makes rational use of the function mechanism of OpenStack and the advantages of Docker container, and realizes the load balance of simple application. At the same time, the service combines the platform integrated code testing tools, and provides a complete code upload, testing and deployment mechanism. Finally, this paper tests the function and response ability of database service and application service through experiment. The results show that users can use database services and application services directly through the unified Web interface of service innovation platform. The function design is in line with the reality and meets the expectations.
