In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Fig. 1 is a first flowchart of a migration method of an application system according to an embodiment of the present disclosure, which is applicable to a case where an application system is transferred from a conventional platform to a cloud platform. The migration method of the application system provided in this embodiment may be executed by a migration apparatus of the application system provided in this embodiment, where the apparatus may be implemented in a software and/or hardware manner and integrated in an electronic device executing the method.
Referring to fig. 1, the method of the present embodiment includes, but is not limited to, the following steps:
and S110, determining a cloud-on-migration mode of the application system.
The cloud-on-migration mode comprises at least one of cloud-on infrastructure, cloud-on container modification and cloud-on application modification. The cloud on the infrastructure refers to a resource carrier of an internet technology supporting an application system, and is migrated from an existing physical machine environment or a virtual environment to a virtual environment of a cloud platform. The cloud application of container transformation refers to that an application access layer (namely a network server) and an application logic layer (namely an application middleware layer including a JAVA environment, middleware and an application program package) are packaged in a container, and automatic deployment and release are carried out through a cloud platform. The application transformation cloud-up refers to supporting the application system to be deployed and operated on the cloud in a container mode, a micro-service framework mode 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 cloud-on-infrastructure, cloud-on-container modification and cloud-on-application modification. Specifically, when the technical architecture of the application system is single, the requirement can be met by adopting a migration cloud mode; when the application system has various technical architectures, at least two migration cloud modes are adopted to meet the requirements. For example: the application part of the application front-end network of the network university can be cloud-modified by adopting a container, and other streaming media services, cache components and the like are only suitable for cloud-on-infrastructure. When more than two modes of cloud migration are selected, namely the mode of cloud migration of the application system belongs to the mixed-mode cloud. How to analyze the service requirement of the application system on the cloud platform will be specifically explained in the following embodiments.
Optionally, determining the cloud-on-migration mode 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 cloud-on-migration mode of the application system is the cloud-on container modification mode, and if not, determining that the cloud-on-migration mode of the application system is the cloud-on infrastructure mode; judging whether the service function of the application system is fixed and/or whether the updating frequency of the version of the application system reaches a preset frequency, if so, determining that the cloud-on-migration mode of the application system is the cloud-on-migration mode of application transformation, and if not, determining that the cloud-on-migration mode of the application system is the cloud-on-infrastructure mode; if the deployment complexity of the application system is high, or the application instance of the application system is greater than a preset threshold value, determining that the migration cloud-up mode of the application system is container modification cloud-up; and if the application system is designed and developed by adopting the micro service architecture, determining that the cloud-on-migration mode of the application system is the cloud-on-application reconstruction mode.
Specifically, the applicable scenario of the migration cloud mode using the cloud on infrastructure as the application system is as follows: 1. the access flow of the application system is stable without obvious peak and valley scenes; 2. the business process of the application system is fixed, the data model is stable, and the application version is rarely changed (such as being updated once in half a year or a year); 3. the service logic of the application system is complex, the service modules are tightly coupled, and the application system is subjected to traditional single application with larger transformation risk, such as marketing; 4. the deployment and the operation of the application system need to use a specific operating system (such as Windows 2003 and the like), and specific functions (such as a cluster file system) of the bottom layer of the operating system are bound, so that the application system cannot be deployed and issued in a container mirror image mode; 5. the method adopts centralized transaction middleware (such as Tuxedo), a centralized service bus, a lightweight relational database, a Nosql database and a cache database application support platform component.
Specifically, the applicable scenario of the migration cloud-up mode using the container transformation cloud-up as the application system is as follows: 1. the load fluctuation of an application system is obvious, and the application system needs to realize elastic expansion in a scene with access flow having a high peak and a low valley (for example, the difference between the concurrency number at the peak period and the concurrency number at the low valley period is large); 2. the deployment of the application system is complex, 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 the application system; 5. the application system can be deployed and published based on the container mirror image without depending on the special mechanism of the underlying operating system.
Specifically, the applicable scenario of the migration cloud-up mode using the application modification cloud-up as the application system is as follows: 1. the service requirements and service functions of the application system change frequently, and the application version is developed in a rapid iteration mode; 2. the application system is designed and developed by adopting a micro-service architecture; 3. the current application system is a traditional centralized architecture, application modules are tightly coupled, and development requirements of the application system in terms of functionality and non-functionality can not be met by upgrading and expanding hardware (if the internet + scene accessed by a large-scale concurrent user exists, the number of concurrent users is too large, and the existing application architecture can not be supported), so that the requirement of cloud formation in application transformation exists; 4. the application system has the requirements of quick online and gray release.
And S120, creating a resource carrier of the application system.
In the embodiment of the present application, it is determined via S110 which migration cloud mode the application system needs to use to complete the migration cloud work of the application system. And then, creating a resource carrier of the application system according to the cloud-on-migration mode of the application system. In addition, a tenant account needs to be created through the cloud console.

Specifically, the cloud on infrastructure is adopted as a migration cloud on application 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 include: 1. computing resources: according to the current resource status of the application system, the configuration quantity and configuration parameters (including parameters such as CPU, memory, local hard disk and cloud hard disk) of the virtual machine and the physical machine are estimated. 2. Network resources: the cloud platform should allocate network resources such as a virtual local area network, an Internet Protocol (IP) Address, a network bandwidth and the like according to the network requirements of the application system, so as to meet cloud deployment and operation in the application. 3. Storage resources: the cloud platform should allocate Storage Area Network (SAN), Network Attached Storage (NAS) or distributed Storage resources according to the structured data Storage and unstructured data Storage needs of the application, provide block Storage, object Storage and file Storage interfaces according to the interface requirements of different applications, and meet the performance needs of the application. 4. Load balancing resources: the Load Balancing component application of the cloud platform meets the requirements of application Load Balancing (SLB) (4 layers or 7 layers) and Global Load Balancing (GSLB). 5. Other resources: the cloud platform should provide an operating system software mirror image template meeting the application deployment requirement, support the backup of the cloud host, and simultaneously meet the full backup and incremental backup of the structured data and the unstructured data.
Specifically, a container modification cloud serving as a migration cloud serving mode of the application system is adopted, and resource requirements of the application system and service requirements of the application system on a cloud platform include: 1. the cloud platform mirror image warehouse is used for providing a layered container base mirror image; 2. the cloud platform should provide selectable container instance specifications; 3. the cloud platform needs to control the network bandwidth configuration among the container instances; 4. the cloud platform needs to provide corresponding NAS storage and distributed storage, and storage requirements of cache data accessed by an application container instance and storage requirements of read-write unstructured data are met; 5. the cloud platform load balancing component application meets the requirements of an application SLB (4 layer or 7 layer) and a GSLB (general service platform); 6. the cloud platform provides an arrangement file of application configuration parameters and environment variables; 7. the cloud platform should satisfy application War package, container base mirror image archiving and management, and should satisfy full backup and incremental backup of structured data and unstructured data; 8. the cloud platform should assign tenants to the migration application separately.
Specifically, the cloud-on-application modification mode is adopted as the cloud-on-migration 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 include: 1. the cloud platform mirror image warehouse is used for providing a micro-service container base mirror image; 2. the cloud platform should provide selectable container instance specifications; 3. the cloud platform needs to provide storage and distributed storage of a corresponding Network File System (NFS), so that storage requirements of cache data accessed by an application container instance and storage requirements of read-write unstructured data are met; 4. carrying out integrated joint debugging with an external system; 5. the cloud platform needs to solve the registration discovery of the service operation period, solve the dynamic adjustment of service configuration and solve the full link monitoring and tracking of the service calling process; 6. the cloud platform needs to provide gateway service, realizes smooth butt joint of a front-end network page and rear-end micro service, and solves the automatic collection and storage of micro service logs and monitoring data; 7. the cloud platform load balancing component application meets the requirements of SLB (4-layer or 7-layer) and GSLB of the micro-service architecture application; 8. the cloud platform provides an arrangement file of micro-service architecture application configuration parameters and environment variables; 9. the cloud platform needs to meet the requirements of filing and management of application Jar packages and container basic mirror images, and simultaneously needs to meet the requirements of full backup and incremental backup of structured data and unstructured data; 10. the cloud platform should assign tenants to the migration application separately.
And 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 requirements of the application system and the service requirements 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 requirement and the service requirement. Illustratively, when a cloud on infrastructure is adopted as a cloud on migration 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 network requirements of the application system, so as to meet cloud deployment and operation on the application.
S130, deploying the application system on the cloud platform according to the migration cloud mode and the resource carrier, and migrating the database of the application system to the cloud so as to finish the migration cloud of the application system.
In the embodiment of the present application, after determining the cloud-on-migration mode and creating the resource carrier for the application system through the above steps, the application system needs to be deployed on the cloud platform according to the selected cloud-on-migration mode and the selected resource carrier.
Specifically, if the migration cloud mode adopts a cloud on infrastructure, the process of deploying the application system on the cloud platform is as follows: the application package of the application system is uploaded to the virtual machine through the tool, the application package of the application system is deployed to the specified middleware according to the design requirement, the middleware starting instruction is manually executed, and the deployment of the application package of the application system is completed.
If the container transformation cloud-up mode is adopted in the migration cloud-up mode, the process of deploying the application system on the cloud platform is as follows: uploading an application package of an application system on a cloud console of a cloud platform, selecting proper container specifications and quantity according to created resource carriers (such as 2 Central Processing Units (CPUs)) and the number of server nodes, and completing configuration of a starting command, a middleware type, a log data pulling address, an elastic expansion strategy and the like of the application system through the cloud console. After deployment is completed, the cloud platform can quickly start the server nodes of the application system, and after the application is started, the access path of the application system can be displayed on the cloud console. And if the access of the application system is successful, indicating that the deployment work of the application package of the application system is completed. Optionally, in order to provide a local load for the production environment system, a load balancing service may be created for the application system through the cloud console, the load balancing service also allocates resources used for load balancing according to the concurrency amount of the application system, and the access path of the application system may be configured into the load balancing after the load balancing service is established.
The process of deploying the application system on the cloud platform by adopting the migration cloud-on-application-modification cloud mode is approximately the same as the process of deploying the application system on the cloud platform by adopting the migration cloud-on-container-modification cloud mode. The difference lies in that: it is also necessary to add a configuration that completes the distributed service bus components through the cloud console on the basis of the created resource carrier.
The cloud-on-migration mode of the cloud in the mixed mode is adopted (namely, the modules of the application system are migrated to the cloud in different cloud-on-migration modes), and the deployment process of the modules of the system on the cloud platform depends on the specific cloud-on-migration mode adopted by the modules. Specifically, a module of the cloud on the infrastructure is adopted to use a deployment mode of the cloud on the infrastructure; the container transformation cloud deployment mode is used by adopting a container transformation cloud deployment module; and the application modification cloud deployment mode is used by adopting the application modification cloud deployment module.
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 used, the cloud work on the database migration is not involved.
According to the technical scheme provided by the embodiment, the cloud-on-migration mode of the application system is determined; creating a resource carrier of the application system; according to the cloud-on-migration mode and the resource carrier, deploying the application system on the cloud platform, and migrating the database of the application system to the cloud so as to complete the cloud-on-migration of the application system. According to the method and the device, a proper cloud mode on migration is determined for the application system by comprehensively considering various factors, a resource carrier is created for the application system, and then the application system is migrated to the cloud platform according to the determined cloud mode on migration and the resource carrier. The technical scheme provided by the embodiment of the application can improve the resource utilization rate of the application system, and brings agility to business application so as to adapt to the innovative demand of business.

In the embodiment of the application, if the container is selected for modification in the cloud-on-migration mode to be cloud-on, the program code and the configuration file of the application system need to be modified, and the modified program code and the modified configuration file are deployed on the cloud platform. The modification of the program code and the configuration file of the application system specifically includes: 1. separating a program code of the application system from a configuration file, wherein the configuration file refers to resource information required by the application system to run on the cloud platform. The advantage of setting up like this is can realize through cloud platform automation deployment application system. 2. The operation data generated by the application system in operation is transferred to the distributed storage or the database, and the setting is that the container resources in the cloud platform are dynamically changed, 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-up mode selects the application modification cloud-up mode, it is first determined whether the application system includes the micro-service. And if the micro-service is not contained in the application system, the micro-service is developed for the application system so as to ensure that the application system can be seamlessly migrated to the platform to run. Setting a configuration file for the developed micro-service, and deploying the micro-service and the configuration file on the cloud platform; the micro-service is operated based on the cloud platform distributed service bus, and the cloud platform distributed service bus has the advantages of realizing service registration discovery and full link monitoring. Optionally, dynamic adjustment of the configuration file during micro-service runtime may be provided.
And S250, deploying the application system on the cloud platform.
In the embodiment of the application, because the cloud on infrastructure is adopted, the operating environment of the application system is not changed (the operating system and the middleware), the database environment of the application system is not changed (the database architecture, the database cluster and the database version) and the application code level is not changed, when the cloud on infrastructure is migrated, the application system adopting the cloud on infrastructure does not involve development and modification of the application system, and is directly deployed on the cloud platform.
S260, judging whether the application system and the external system have an integration relation, if so, executing S270, and if not, executing S280.
In the embodiment of the application, when the application system is migrated to the cloud, the integration relationship and the technical route between the application system and the external system need to be analyzed, so as to determine whether the application system and the external system have the integration relationship. Wherein, the external system refers to other application systems. Optionally, the integration relationship between the internal components of the application system can also be analyzed.

Specifically, when the migration cloud mode is the mixed mode cloud mode, the testing work of each module of the system depends on the specific migration cloud mode adopted by the module. The module adopting the cloud on the infrastructure uses a test mode of the cloud on the infrastructure, the module adopting the container transformation cloud uses a test mode of the container transformation cloud, and the module adopting the application transformation cloud uses a test mode of the application transformation cloud.
