Abstract: In order to build the intelligent Monghua ecological circle, a unified enterprise-level cloud development and operation environment is indispensable. Using the open source cloud architecture of Cloud Foundry, this article studied and designed the architecture design of the development platform from various perspectives and levels, and constructed a unified application development platform with flexible architecture, complete functions, excellent performance, selfdiagnosis, self-tuning and easy to use. The platform provided enterprise-level services, which had the characteristics of Platform as a Service (PaaS) and Date as a Service (Daas). It could implemented rapid development, rapid deployment and rapid integration of cloud applications. Users could quickly and easily create, deploy, and manage applications on the platform without knowing how to install or configure them, and could also easily and quickly find the required services on the development platform to create, deploy and manage the required applications.
