@thom.code: Part 1 ~ Every Major DevOps Tool Explained Follow one line of code from a developer’s laptop all the way to millions of users — and meet every major DevOps tool along the way, in plain English. We explain every major DevOps tool by tracing a single change through the whole pipeline: Git and GitHub for saving and reviewing code, Jenkins, GitHub Actions, and GitLab for building and testing it automatically (CI/CD), and SonarQube for keeping it clean. Then Terraform builds the cloud servers, Ansible sets them up, and Docker packs the app into a container so it runs the same everywhere — with Kubernetes managing hundreds of them at scale and Argo CD releasing new versions straight from Git. Vault protects the passwords and keys, while Prometheus, Grafana, and the ELK Stack watch everything live. And when the shop starts failing at 3 a.m., you’ll see exactly how an engineer gets woken up, finds the cause in the logs, and fixes it — which is why DevOps is drawn as a loop, not a line. Perfect if these tool names have always blurred together. 🔔 Subscribe for more tech explained in plain English — new videos every week. 💬 Got a topic you want explained next?
