【摘要】：随着近几年移动互联网的普及,电商行业飞速发展;平台入口流量增长迅猛,入驻服务商规模不断扩大。同时,很多ISV(independent software vendor,独立软件开发商)和品牌商的系统都运行在电商企业平台的主链路上,因此保障这些第三方系统的稳定性也成为了电商平台的运营要旨。云计算技术的引入,能够很好地解决上述矛盾。通过对品牌商、ISV等电商生态角色的IT系统的容器化改造,可以高效地管理入驻商的服务;在为其提供产品化解决方案的同时,降低系统运维成本,达到技术赋能商家、繁荣电商生态的效果。本文为苏宁云商提出了基于Cloud Foundry实现的电商云解决方案。首先,基于特定IaaS的PaaS平台自动化部署与运维管理一直都是一个棘手的问题。本文通过对BOSH CPI的扩展,完成了 PaaS平台与苏宁IaaS支撑中心的高度集成;其次,对于云平台的单点故障问题,本文通过Keepalived技术实现负载均衡器HAProxy的主从备份,增强了电商云的容灾能力。同时,出于安全角度的考量,本文设计并实现了支持入驻商应用程序SSL证书的管理系统。最后,利用GlusterFS分布式文件技术取代NFS Server,优化了云平台的存储系统。基于Cloud Foundry的电商云解决方案很好地实现了苏宁云商生态中入驻商系统和服务的容器化改造,使得入驻商能够方便地与苏宁云商系统进行技术和系统上的对接,实现高质量架构产品化输出的目标。
[Abstract]:With the popularity of the mobile Internet in recent years, the e-commerce industry has developed rapidly; the platform entrance traffic is growing rapidly, and the scale of resident service providers is expanding.At the same time, many ISV(independent software vendor-independent software developers) and brands run on the main chain of the e-commerce enterprise platform, so ensuring the stability of these third party systems has become the key point of the e-commerce platform.The introduction of cloud computing technology, can solve these contradictions well.Through the container transformation of IT system with the ecological role of ISV, we can manage the service of the resident business efficiently, and at the same time, we can reduce the cost of operation and maintenance of the system, and achieve the technology enabling business, while providing a production-oriented solution for it.The effect of prosperity of ecommerce ecology.This paper puts forward a solution based on Cloud Foundry for Su Ning cloud quotient.First of all, automated deployment and operation management of PaaS platform based on specific IaaS has always been a thorny problem.Through the extension of BOSH CPI, this paper completes the high integration of PaaS platform and Su Ning IaaS support center. Secondly, for the single point fault of cloud platform, this paper realizes the master-slave backup of load balancer HAProxy by Keepalived technology.Enhanced the electric business cloud disaster tolerance ability.At the same time, for the consideration of security, this paper designs and implements a management system supporting SSL certificate.Finally, the storage system of cloud platform is optimized by replacing NFS Server with GlusterFS distributed file technology.The electronic business cloud solution based on Cloud Foundry has well realized the container transformation of the entry business system and service in Su Ning's cloud business ecology, which makes it easy for the entrant to connect with the Su Ning cloud business system in technology and system.Achieve the goal of high quality architecture output.
