A Simple Guide for Beginners: Jenkins → GitLab → GitHub → GitOps
Hello!
Are you just starting your DevOps journey or tired of hearing “and we use CI/CD” in interviews? Want to finally understand why code that works on your laptop fails on the server?
This article is your first step toward automation. And it will really be easy.
We’ll break everything down, without overloaded terms and with examples.
What is CI/CD (very simple)
CI/CD is when you press git push and everything else happens automatically.

Introduction
Unlike Caddy, which focuses on simplicity, Traefik (pronounced Traffic) was built to solve one specific task: routing traffic in dynamic environments.
It is a reverse proxy and load balancer designed specifically for Docker, Kubernetes, and other orchestrators.
The main difference from Nginx is not static configuration, but the ability to automatically discover and serve services.
Key Concepts: Dynamic Configuration
The philosophy of Traefik is built on the principle of Service Discovery.

Loki + Grafana: A Lightweight and Cost-Effective Logging Solution for the Cloud
We’re wrapping up our series on centralized logging with a modern and innovative solution: Loki together with Grafana. Developed by Grafana Labs, this stack reimagines how logging works — making it simple, efficient, and especially appealing for those already using Prometheus.
What Is Loki and How Does It Work?
Loki is a log aggregation system designed to minimize resource usage. It indexes only metadata (labels), while the log messages themselves are stored in compressed form — following the same philosophy as Prometheus, but for logs.

We’ve reviewed Munin as a simple solution for basic monitoring. Now let’s move on to a stack that has become an indispensable tool in the world of modern cloud infrastructure, microservices, and containers: Prometheus, Node Exporter, and Grafana. This trio provides a powerful, flexible, and scalable approach to collecting, storing, analyzing, and visualizing metrics.
What is Prometheus and Its Ecosystem?
Prometheus is an open-source monitoring system originally developed at Google and later handed over to the Cloud Native Computing Foundation (CNCF). Its key feature is the “pull” model: Prometheus scrapes metrics from targets via HTTP endpoints.
