Technical Field
The invention relates to the technical field of cloud native program control, in particular to a method and a device for automatically adapting a plurality of external registries to service grid Istios.
Background
With the development of information technology, the complexity of the system is higher and higher, and the data interaction is more and more complex. Monomer applications have become increasingly unable to meet the requirements of high-concurrency, high-performance systems as a traditional application deployment approach. Thus, there is a need to solve the problems faced by monomer applications through distributed applications. With the application of distributed system architecture, more and more responsibilities of a single mini-service are presented. These service network interactions, traffic management, information security are also becoming more and more challenging. In order to solve the problem of the falling to the ground and the application of the distributed architecture, more and more frames are developed in the technical field to meet the existing requirements. The service grid is a management mode of micro services in the frames, and the essential purpose is to manage the flow of the micro services, monitor the micro service state and display the call links in real time.
The registration center is arranged to solve the problems of multiple micro services, complex routing and quick application state change in the distributed architecture. The distributed micro-services become orderly and easy to manage by registering all the micro-services to a registration center, automatically discovering the state of the services and dynamically reporting the routes of the services. When the external registry registers a service in a service grid, the external registry is required to separately develop a private protocol that the code supports the service grid. And this protocol is a proprietary protocol specific to the service grid. There is sometimes a need to satisfy multiple external registries to register services in a service grid, requiring each registry to implement a proprietary protocol for the service grid, and there is a significant amount of adaptation development effort. Based on this scenario, it is conventional practice to implement a set of protocol codes per registry code to perform the function according to the new protocol type. As more registries are accessed, a new set of codes needs to be developed to support each time a registry is accessed. Development cost and labor cost are high. And when the registry does not realize the protocol, the service cannot be registered in the service grid, and the adaptability is poor.
Therefore, how to provide a method for automatically adapting multiple external registries to service grid ission is a technical problem to be solved.
