Design and implement microservices in Go with clean architecture, gRPC communication, and distributed tracing.

Go's simplicity and performance make it an excellent choice for building microservices architectures.

Service Architecture

Each microservice should have a single responsibility and communicate through well-defined APIs.

go
3package main
4
5import (
6    "context"
7    "net/http"
8    "time"
9
10    "github.com/gin-gonic/gin"
11    "go.opentelemetry.io/otel"
12    "go.opentelemetry.io/otel/trace"
13)
14
15type UserService struct {
16    tracer trace.Tracer
17}
18
19func (s *UserService) GetUser(c *gin.Context) {
20    ctx, span := s.tracer.Start(c.Request.Context(), "get-user")
21    defer span.End()
22    
23    userID := c.Param("id")
24    user, err := s.fetchUser(ctx, userID)
25    if err != nil {
26        c.JSON(http.StatusInternalServerError, gin.H{"error": err.Error()})
27        return
28    }
29    
30    c.JSON(http.StatusOK, user)
31}

gRPC Communication

Use gRPC for efficient inter-service communication with type safety and automatic code generation.

Well-designed microservices enable teams to work independently while maintaining system coherence.
