Technical Field

The invention relates to the technical field of registries in micro-service frameworks, in particular to a method for automatically discovering heterogeneous micro-services.

Background

Micro-service architecture is a service-oriented architecture style that improves the flexibility and scalability of the system by splitting an application into a small, loosely coupled set of services. While the registry is one of the key components in the micro-service architecture, it serves a key role in service discovery and routing, which serves to manage and maintain metadata information for individual micro-service instances, including service names, addresses, versions, etc. It allows service providers to register their services with a registry, while also allowing service consumers to query and discover available service instances, providing support for communications between the service providers and service consumers.

Furthermore, because different micro-service frameworks may use different registry components, this makes it difficult to uniformly overview and manage different types of service instances. Conventional registries are generally only suitable for a single micro-service framework, and have a plurality of problems for centralized management and control of service instances of a plurality of micro-service frameworks. Therefore, the development of a compatible, universal and efficient service automatic discovery system is of great practical significance to meet the requirements of various micro-service frameworks.
