12-Factor App
Hands-on 12-Factor App Course
Learn the 12-Factor App methodology by building a real microservice application in Go using modern DevOps practices
The 12-Factor App course is designed to offer DevOps engineers and developers a deep understanding of the principles of building modern cloud-native applications.
At the start of the course you'll learn the fundamentals of the 12-Factor App methodology, learn to design microservice architecture, and create a basic application structure using Go, Echo, and telebot.
Next, the course will cover working with databases (PostgreSQL, Redis), containerizing the application with Docker, and deploying it to Kubernetes. You'll learn to set up CI/CD using GitHub Actions and self-hosted runners.
Special attention will be paid to ensuring dev/prod parity, scaling the application, and ensuring its fault tolerance. You'll learn to apply all 12 principles of the methodology in practice.
This course will allow you to become competent in building modern cloud-native applications that follow DevOps best practices and the 12-Factor App methodology.
