With the continuous development of new IT technologies, such as cloud computing, big data, artificial intelligence and so on, the scale of the dispatching and control cloud they build is expanding continuously. At the same time, the number of the services of the dispatching and control cloud are also increasing greatly. This all makes the man-made operation and maintenance mode of the dispatching and control cloud inefficient and of high error rate. It is difficult to guarantee the safe and high-quality operation of a power grid and the lean and efficient operation of the dispatching management. A Continuous Integration and Continuous Deployment (CI/CD) platform can achieve efficient and accurate maintenance of the dispatching and control cloud. In this paper, the CI/CD platform, which consists of the Jenkins, Gitlab and Ansible, is introduced to complete the operation and maintenance tasks of the dispatching and control cloud, such as automatic build, version control, and batch deployment. Finally, through the simulation of the dispatching and control cloud, it is verified that this scheme can reduce operation and maintenance workloads and improve work efficiency.
