The invention discloses a software release method and a software release device based on a cloud computing platform. The method relates to the field of communication and cloud computing, and comprisesthe steps that after a cloud computing platform obtains codes used for providing different services and contained in software, compiling processing is executed on at least one code passing inspectionaccording to received configuration information to obtain a mirror image file corresponding to each code; when it is determined that an integration test needs to be executed according to the configuration information, an integration test script is used for carrying out an integration test on a mirror image file corresponding to at least one code passing the inspection, and the mirror image file passing the test is published to a test environment; and the mirror image file passing the test in the test environment is published and online. By setting the development, test and operation and maintenance functions on the cloud computing platform, the cloud computing platform automatically checks, compiles, tests and publishes the codes after obtaining the codes, so that the online efficiency ofpublishing from development to operation and maintenance is improved, and meanwhile, the workload of operation and maintenance and the risk of man-made misoperation are reduced.
