The access process of Spring Cloud microservices is as follows:

  1. The client initiates a request, which then reaches the API Gateway.
  2. The API Gateway determines the microservice requested based on the URL of the request.
  3. The API Gateway utilizes a load balancing algorithm to select an available microservice instance.
  4. API Gateway forwards requests to the selected microservice instance.
  5. Microservice instance receives requests and processes them.
  6. The microservice instance will return the processed results to the API Gateway.
  7. The API Gateway sends the results back to the client.

In the entire process, the API Gateway serves as the entry point for microservices, responsible for routing and forwarding requests. Clients access microservices through the API Gateway, without needing to directly interact with the microservice instances. With the ability to handle load balancing, the API Gateway enables high availability and scalability of microservices. Additionally, the API Gateway can offer common functionalities such as authentication, authorization, and rate limiting to enhance system security and availability.
