This book details the creation of an advanced DevOps ecosystem for the complete automation of IT environments. Based on the principles of GitOps, ephemerality and immutability, the architecture uses Jenkins as the central orchestrator, with dynamic agents in Kubernetes. The infrastructure is provisioned as code with Terraform, while Puppet and Ansible manage the layered configuration. Security is guaranteed by HashiCorp Vault, and the lifecycle is managed by Redmine, with monitoring via Zabbix and Grafana. The book explores how to integrate Gemini AI to optimize pipelines, generate code and predict failures, transforming traditional automation into intelligent automation. It analyzes the solution's strengths and weaknesses, offering mitigation strategies and discussing the future of Platform Engineering, AIOps and FinOps. It is a complete guide to building, operating and evolving a modern, secure and efficient software delivery platform.
