As the core of informatization construction of large-scale architectural design enterprises, the production business platform plays an important role in collaborative design, quality check, and data management. Facing the construction needs of the production platform of large-scale architectural design enterprises, this paper creates an integrated platform based on cloud architecture for the whole life cycle business application and management to be used by architects and managers, which takes the production business data management as the core, and interconnected production and working environment to realize horizontal integration and vertical connectivity of business chain in engineering construction industry. Users are able to efficiently carry out production management in a unified data environment. In view of the construction needs and goals, this paper puts forward the overall structure of the production business platform for large-scale architectural design enterprises, which is divided into four levels of platform portal, digital production management, data management and big data support. At the same time, the overall technical route of the platform based on micro-service architecture is proposed, which includes five characteristics and four key technologies to achieve high-level performance and availability. The main idea and method of building production business platform proposed in this paper are intending to provide reference for the construction of production platforms for large-scale architectural design enterprises in the industry, to promote the integration of information technology between the Internet information technology and the construction industry, and to improve the informationization level of architectural design enterprises in the industry.
