Further, to facilitate the recovery of the first application, the material module 503 also stores the material of the first application acquired from the persistent integration platform into the material server.
After obtaining the material of the first application, the application deployment module 504 deploys the first application on the target server using the material of the first application, for example, if the target server is server a and server B, the first application is deployed on server a using the material of the first application, and the first application is deployed on server B.
When the first application is deployed, the first application can be deployed by using the release script of the first application, specifically, the application automation deployment system calls the release script and executes the release action on the target server, so that the first application can be deployed on the target server based on the material of the first application.
In this embodiment of the present invention, after the target server completes the deployment of the first application, the saving module 502 saves the target server information, the configuration information of the first application, and the material information of the first application to the central configuration database, so as to form a snapshot of the first application.
In the embodiment of the invention, each time the application is deployed on the target server by the application automation deployment system, the target server information, the deployed application configuration information and the application material information need to be stored in the central configuration database to form the application snapshot, so that when the server fails, the application recovery can be realized based on the application snapshot in the central configuration database, and a basis is provided for the automatic recovery of the application.
Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (such as a mobile phone, a computer, a server, an air conditioner, or a network device) to execute the method according to the embodiments of the present invention.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
