DevOps Infrastructure Automation with Terraform, Ansible, and Prometheus

Scaling and managing servers manually is slow, error-prone, and unsustainable for modern development teams. Transitioning to DevOps requires mastering the tools that automate infrastructure provisioning, configuration, and observability. This written course guides you through the process of designing a fully automated, monitored Linux cluster from scratch. You will progress from foundational concepts of Infrastructure as Code (IaC) and configuration management to implementing a complete observability pipeline with real-time alerting. By reading through clear, step-by-step explanations and analyzing structured configuration files, you will gain a deep understanding of how modern cloud infrastructure fits together. What you'll learn: - Provision cloud servers and manage infrastructure state declaratively using Terraform. - Automate server configuration, package installation, and security updates with Ansible playbooks. - Configure a Prometheus monitoring server to collect system and application metrics. - Design interactive Grafana dashboards to visualize cluster health and performance. - Set up Alertmanager to trigger notifications when critical system thresholds are exceeded. - Apply modern DevOps best practices for secure secret management and modular code organization. The course begins with essential terminology and core architectural concepts before guiding you through the practical integration of each tool. You will reinforce your learning through written configuration exercises and conceptual review questions designed to solidify your engineering skills. This course is designed for system administrators, developers, and IT professionals who have a basic familiarity with the Linux command line and want to transition into DevOps. No prior experience with automation or monitoring tools is required. Start building your automated infrastructure today.
