About this course
DevOps engineers are among the best-paid and most in-demand people in tech, and many work remotely for companies anywhere in the world. This path takes you from zero — never having opened a terminal — to building the kind of automated, monitored, cloud-hosted system that real teams run. You learn in the order professionals use the tools: Linux and the command line, shell scripting, Git, networking, containers with Docker, orchestration with Kubernetes, CI/CD pipelines, infrastructure as code with Terraform and Ansible, the AWS cloud, monitoring with Prometheus and Grafana, and finally GitOps, security and reliability. Each part ends with a hands-on lab, and your capstone is a complete pipeline you can show employers. Expect around 40 hours of video plus practice — about 3 months at an hour a day.
