Abstract: Under the traditional software delivery mode, different teams are responsible for each step, which has problems such as difficult cooperation, long delivery cycle, low efficiency and unguaranteed quality. In view of the above, an integrated R&D, operation and maintenance platform based on DevOps concept is designed. Benchmarking the three-level standard of the continuous delivery maturity model of the China Academy of Information and Communication Technology, taking the project as the dimension, it opened up the links of demand, R&D, testing, operation and maintenance, realized the integration and automation of the whole process of software delivery, and ensured the high quality, high availability and high efficiency of software delivery. The experimental results show that the requirement response cycle is increased by 53.2% and the online bug is reduced by 86.2% using this platform compared with the traditional delivery method.
