What tools and approaches have you used in creating microservices architecture?

When creating microservices architecture, I used the following tools and approaches:

• Business Function Separation: Each microservice is responsible for a specific business logic, which simplifies support and scaling.
• API and Communication: Used REST or gRPC for interaction between services, sometimes employing asynchronous queues (e.g., Kafka, RabbitMQ) for event-driven communication.
• Containerization: Docker for packaging services, which facilitates deployment and isolation.
• Orchestration: Kubernetes for managing scaling, updates, and fault tolerance.
• Monitoring and Logging: Prometheus, Grafana, ELK stack for tracking service status and quick problem response.
• CI/CD: Automation of build, testing, and deployment using Jenkins, GitLab CI, or other tools.

Example of a simple HTTP service in Go:

package main

import (
    "net/http"
    "log"
)

func handler(w http.ResponseWriter, r *http.Request) {
    w.Write([]byte("Hello from microservice"))
}

func main() {
    http.HandleFunc("/", handler)
    log.Fatal(http.ListenAndServe(":8080", nil))
}

This service can be packaged into a container and deployed within a microservices architecture.
