With the development of information technology, the system complexity is higher and higher, and the data interaction is more and more complex. The single application, as a traditional application deployment approach, has gradually failed to meet the requirements of high-concurrency, high-performance systems. Therefore, there is a need to solve the problems faced by monolithic applications through distributed applications. With the application of distributed system architectures, more and more single-responsibility microservice has emerged. These services network interactions, traffic management, information security are also becoming increasingly challenging. In order to solve the problem of landing and application of a distributed architecture, more and more frames are developed in the technical field to meet the existing requirements. The service grid is just a management mode for the micro-services in the frameworks, and the essential purpose is to control the flow of the micro-services, monitor the state of the micro-services and display the calling link in real time.
The registration center appears to solve the problems of multiple micro services, complex routing and fast application state change in the distributed architecture. The distributed micro services are ordered and easy to manage by registering all the micro services in a registration center, automatically discovering the states of the services and dynamically reporting the routes of the services. When the external registry registers the service into the service grid, the external registry is required to separately develop codes to support the proprietary protocol of the service grid. And this protocol is a proprietary protocol specific to the service grid. Sometimes, it is necessary to satisfy that a plurality of external registries register services in a service grid, each registry is required to implement a proprietary protocol of the service grid, and a large amount of adaptive development work exists. Based on this scenario, it is conventional to implement a set of protocol codes for each registry code to complete the function according to the new protocol type. As more registries are accessed, each time a registry is accessed, a new set of code needs to be developed to support the new access. The development cost and the labor cost are high.
