Networking basics

DNS, HTTP, ports and firewalls — how machines actually talk to each other, which explains most "it's not connecting" bugs.

STAGE 03 · WORKFLOW

Version control with Git

Branching, merging, pull requests — the shared language every team uses to move code without stepping on each other.

STAGE 04 · WORKFLOW

Scripting & automation

Bash and Python for the tasks you don't want to do by hand twice — the real starting point of "ops" work.

STAGE 07 · SCALE

Orchestration with Kubernetes

Running many containers reliably — scheduling, scaling and healing them without babysitting every one by hand.
