Example 1
Fig. 1 is a schematic flow chart of a migration method of an application system according to an embodiment of the present application, where the embodiment is applicable to a situation in which an application system is transferred from a conventional platform to a cloud platform.

Referring to fig. 1, the method of the present embodiment includes, but is not limited to, the following steps:
s110, determining a migration cloud mode of the application system.
The migration cloud mode comprises at least one of an infrastructure cloud, a container transformation cloud and an application transformation cloud. The cloud on the infrastructure refers to a resource carrier supporting the internet technology of the application system, and the resource carrier is migrated from the existing physical machine environment or the virtualization environment to the virtualization environment of the cloud platform. The cloud transformation of the container means that an application access layer (i.e. a network server) and an application logic layer (i.e. an application middleware layer comprising a JAVA environment, middleware and an application program package) are packaged in the container, and automatic deployment and release are performed through a cloud platform. Application transformation cloud loading refers to supporting application systems to be deployed and operated on the cloud through a container, a micro-service framework and the like.
In the embodiment of the application, according to the technical architecture type of the application system and the service requirement of the application system on the cloud platform, the application system is evaluated and determined to be based on one or more of three modes of infrastructure cloud, container transformation cloud and application transformation cloud. Specifically, when the technical architecture of the application system is single, a migration cloud-up mode is adopted to meet the requirements; when the application system has a plurality of technical architectures, at least two migration cloud-up modes are adopted to meet the requirements. For example: the front-end network application part of the network university application can adopt a container to reform the cloud, and other streaming media services, cache components and the like are only suitable for the cloud on the infrastructure. When more than two migration cloud modes are selected, namely the migration cloud modes of the application system belong to the mixed mode cloud. How to analyze the service requirements of the application system on the cloud platform will be specifically explained in the following embodiments.
Optionally, determining the cloud mode on migration of the application system includes at least one of: judging whether the access flow of the application system has peaks and valleys, if so, determining that the migration cloud loading mode of the application system is container transformation cloud loading, and if not, determining that the migration cloud loading mode of the application system is basic framework cloud loading; judging whether the service function of the application system is fixed and/or whether the update frequency of the version of the application system reaches a preset frequency, if so, determining that the migration cloud-up mode of the application system is application transformation cloud-up, and if not, determining that the migration cloud-up mode of the application system is basic framework cloud-up; if the complexity of the deployment of the application system is high, or the application instance of the application system is larger than a preset threshold, determining that the cloud mode of the migration of the application system is the cloud of the container transformation; and if the application system is designed and developed by adopting the micro-service architecture, determining that the migration cloud loading mode of the application system is application transformation cloud loading.

Specifically, the application scenario of adopting the container transformation cloud as the migration cloud mode of the application system is as follows: 1. the load fluctuation of the application system is obvious, the access flow has a scene of peak and valley (such as a larger difference between the concurrent number in the peak period and the concurrent number in the valley period), and the application system needs to realize elastic expansion; 2. the deployment of the application system is complicated, the configuration file is easy to make mistakes (if a large number of configuration operations exist), and the application system has the requirements of quick, standard and automatic deployment; 3. the application system has more application examples and has the requirements of unified log and unified monitoring; 4. separating service logic and service state data of an application system; 5. the application system can be deployed and published based on the container image without relying on a special mechanism of the underlying operating system.
Specifically, the application scenario of adopting the application transformation cloud as the migration cloud mode of the application system is as follows: 1. the service requirements and service functions of the application system are frequently changed, and the application version is subjected to rapid iterative development; 2. the application system adopts micro-service architecture design and development; 3. the current application system is a traditional centralized architecture, application modules are tightly coupled, development requirements on the functionality and non-functionality aspects of the application system (such as the existence of an Internet+scene accessed by a large-scale concurrent user, too large number of concurrent users and the inability of the existing application architecture to support) cannot be met through upgrading and capacity expansion hardware, and the requirement of application transformation and cloud loading exists; 4. the application system has the requirements of quick online and gray level release.

Load balancing resources: the load balancing component application of the cloud platform meets the application load balancing (Server Load Balancer, SLB) (layer 4 or 7), global load balancing (Global Server Load Balancing, GSLB) requirements. 5. Other resources: the cloud platform should provide an operating system software mirror image template meeting the application deployment requirements, support the cloud host backup, and simultaneously should satisfy the full backup and incremental backup of structured data and unstructured data.
Specifically, the cloud model of the application system is a cloud model of the application system in the process of transforming the container into the cloud, and the resource requirements of the application system and the service requirements of the application system on the cloud platform comprise: 1. the cloud platform mirror warehouse should provide layered container base mirrors; 2. the cloud platform should provide selectable container instance specifications; 3. the cloud platform needs to control the network bandwidth configuration among container examples; 4. the cloud platform needs to provide corresponding NAS storage and distributed storage so as to meet the storage requirements of cache data accessed by an application container instance and read-write unstructured data; 5. the cloud platform load balancing component application meets the requirements of application SLB (4 layers or 7 layers) and GSLB; 6. the cloud platform should provide the arrangement files of the application configuration parameters and the environment variables; 7. the cloud platform can meet the requirements of archiving and managing application War package and container base mirror images, and can meet the requirements of full backup and incremental backup of structured data and unstructured data; 8. the cloud platform should assign tenants individually to the migration applications.
Specifically, the application transformation cloud is adopted as a migration cloud mode of the application system, and the resource requirements of the application system and the service requirements of the application system on the cloud platform comprise: 1. the cloud platform mirror image warehouse should provide a basic mirror image of the micro service container; 2. the cloud platform should provide selectable container instance specifications; 3. the cloud platform needs to provide corresponding network file system (Network File System, NFS) storage and distributed storage, so that the storage requirements of cache data accessed by an application container instance and read-write unstructured data are met; 4. performing integrated joint debugging with an external system; 5. the cloud platform needs to solve the registration discovery of service operation period, solve the dynamic adjustment of service configuration and solve the full-link monitoring tracking of the service calling process; 6. the cloud platform needs to provide gateway services, so that smooth butt joint of front-end network pages and rear-end micro services is realized, and automatic collection and storage of micro service logs and monitoring data are solved; 7. the cloud platform load balancing component application meets SLB (4 layers or 7 layers) and GSLB requirements of the micro-service architecture application; 8. the cloud platform should provide the configuration files of the application configuration parameters and the environment variables of the micro-service architecture; 9. the cloud platform can be used for archiving and managing Jar package application and container base mirror images, and can be used for fully and incrementally backing up structured data and unstructured data; 10. the cloud platform should assign tenants individually to the migration applications.
S1202, creating a resource carrier of the application system according to the resource requirement and the service requirement.
In the embodiment of the present application, through the step S1201, the resource requirement of the application system and the service requirement of the application system on the cloud platform are analyzed. And then creating a resource carrier for the application system on the cloud platform according to the resource requirements and the service requirements. For example, when the cloud on the infrastructure is used as a migration cloud on mode of the application system, the cloud platform should allocate network resources such as a virtual local area network, an IP address, a network bandwidth and the like according to the network requirements of the application system so as to meet the deployment and operation of the application cloud.
S130, deploying an application system on a cloud platform according to the migration cloud-up mode and the resource carrier, and migrating a database of the application system to the cloud so as to complete migration cloud-up of the application system.
In the embodiment of the application, after determining the migration cloud mode and creating the resource carrier for the application system through the steps, the application system needs to be deployed on the cloud platform according to the selected migration cloud mode and the resource carrier.
Specifically, if the cloud mode of migration adopts an infrastructure cloud, the process of deploying the application system on the cloud platform is as follows: and uploading the application package of the application system to the virtual machine by using a tool, deploying the application package of the application system into a designated middleware according to the design requirement, and manually executing a middleware starting instruction to complete the deployment of the application package of the application system.
If the cloud mode is to use container transformation to cloud, the process of deploying the application system on the cloud platform is as follows: and uploading an application package of the application system on a cloud console of the cloud platform, selecting proper container specifications and number according to the created resource carriers (such as 2 central processing units (Central Processing Unit, CPU) 4G memories) and the number of server nodes, and completing configuration of starting commands, middleware types, pulling addresses of log data, elastic expansion strategies and the like of the application system through the cloud console. After deployment, the cloud platform can quickly start the server node of the application system, and after application is started, the access path of the application system can be displayed on the cloud console. If the application system access is successful, the deployment work of the application package of the application system is indicated to be completed. Optionally, in order to provide a local load for the production environment system, a load balancing service can be created for the application system through the cloud console, the load balancing service also distributes resources used by load balancing according to the concurrency of the application system, and after the load balancing service is established, an access path of the application system can be configured into load balancing.
The process of deploying an application system on a cloud platform using a migration-on-cloud mode of an application transformation-on-cloud is substantially the same as the process of deploying an application system on a cloud platform using a migration-on-cloud mode of a container transformation-on-cloud. The difference is that: the configuration of the distributed service bus assembly is completed through the cloud console on the basis of the created resource carrier.
And adopting a migration cloud mode of the hybrid mode cloud (namely, migration cloud is carried out on each module of the application system by different migration cloud modes), wherein the deployment process of each module of the system on the cloud platform depends on the specific migration cloud mode adopted by the system. Specifically, a cloud module on an infrastructure is adopted to use a cloud deployment mode on the infrastructure; a container transformation cloud-up module is adopted, and a container transformation cloud-up deployment mode is used; and the application transformation cloud module is used for transforming the cloud deployment mode.
In the embodiment of the application, after the application package of the application system is deployed to the cloud platform, if a new database needs to be used in the cloud platform, data in an original database before the application system is migrated to the cloud is migrated to the new database.
It should be noted that, after the application package of the application system is deployed to the cloud platform, if the original database is still adopted, the cloud migration work of the database is not involved.
According to the technical scheme provided by the embodiment, the cloud migration mode of the application system is determined; creating a resource carrier of an application system; and deploying the application system on the cloud platform according to the migration cloud-up mode and the resource carrier, and migrating the database of the application system to the cloud so as to complete migration cloud-up of the application system. According to the method, the device and the system, the appropriate migration cloud-up mode is determined for the application system by comprehensively considering factors of all aspects, a resource carrier is established for the application system, and then the application system is migrated to the cloud platform according to the determined migration cloud-up mode and the resource carrier. The technical scheme provided by the embodiment of the application system can improve the resource utilization rate of the application system, bring agility to business application and adapt to the innovative requirements of business.

The modification of the program code and configuration file of the application system specifically comprises: 1. and separating program codes of the application system from configuration files, wherein the configuration files refer to resource information required by the application system to run on the cloud platform. The advantage of this arrangement is that automated deployment of the application system via the cloud platform can be achieved. 2. The running data generated by the application system during running is transferred to the distributed storage or database, so that the configuration is that the container resources are dynamically changed in the cloud platform, and the data stored in the container is automatically emptied along with the end of the life cycle of the container.
In the embodiment of the application, if the migration cloud mode selects application modification cloud, it is first determined whether the application system includes a micro service.

Setting a configuration file for the developed micro-service, and deploying the micro-service and the configuration file on a cloud platform; the micro-service is operated based on the cloud platform distributed service bus, and the cloud platform distributed service bus is adopted to realize service registration discovery and full-link monitoring. Alternatively, dynamic adjustment of the configuration file to the micro-service runtime may be provided.

Wherein the external system refers to other application systems. Alternatively, the integration relationship between the internal components of the application system may also be analyzed. If the integration relationship exists, executing S270; if no integration relationship exists, S280 is performed.
