What kind of inter-service interaction did you have in one of your recent projects?

In one of the recent projects, inter-service communication was implemented via REST API using JSON for data exchange. One service provided data via HTTP requests, while another consumed and processed them. To improve reliability, retry mechanisms and timeouts were used. gRPC was also employed for high-performance interaction between internal services.

Example of a simple REST client in Go:

resp, err := http.Get("https://api.example.com/data")
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
// process body
