DevOps Tools for Developers (2022)

Description: Knowledge can be applied by a developer in any programming…


Knowledge can be applied by a developer in any programming language.

Carry multiple services in Python through all integrations.

By the basics and best practice we’ll show the whole communication system of a working application. The course is fine if now: I’m writing normal code, but what’s next… knows what’s next.

Step 1 – Local environment and loops

You will learn that today it is easy to create a local environment identical to loops. We’ll also break down the nuances of a competent application that aren’t covered enough. There are more than 12 factors.

Stack and theory:

  • Vagrant
  • Docker
  • A competent application

Step 2 – Deployment – CI

You’ll see the first bundles of application elements using Docker Compose and understand the difference between CI tools.


  • Docker Compose
  • Github Actions
  • Gitlab CI
  • Jenkins
  • Team City

Step 3 – Working with Data

You’ll see the difference between connecting databases, message brokers, and how to roll migrations.

Stack and theory:

  • PostgreSQL
  • MySQL
  • Oracle
  • Redis
  • Apache Kafka
  • Rabbit
  • Database Migrations

Step 4 – Balancing and networking

In this phase we will configure the web server, load balancing and touch on the topic of service mesh.


  • Nginx
  • Apache
  • Envoy
  • Istio

Step 5 – Monitoring and Logging

You’ll learn how to set up metrics, logging, why it’s needed, what options there are, and look at tracing services with Jaeger.

Stack and theory:

  • Prometheus
  • Zabbix
  • Elastic Stack
  • Loki
  • Jaeger
  • Grafana
  • Alerts

Step 6 – Security

We’ll look at static and dynamic security at the application layer, as well as basic security against DDos at Layer 2 and Layer 3 of the OSI network model.

Stack and theory:

  • SonarQube
  • Dynamic analysis and other types
  • DDoS: Nginx log analysis

Step 7 – Deployment.

In the final step, let’s go back to automation and deplot our services and see the difference in the possible tools.


  • Gitlab CI.
  • Jenkins
  • Ansible
