Cloud & DevOps Roadmap

Linux is the operating system that runs most servers on the internet. Learning Linux means understanding how to navigate the filesystem, manage processes, configure services, and automate tasks — all from the command line.

Networking fundamentals cover how computers communicate: IP addresses, DNS, HTTP, ports, firewalls, and protocols. It is the foundation for understanding how the internet, cloud, and distributed systems work.

The command line (terminal) is a text-based interface for interacting with your computer. Instead of clicking through folders and menus, you type commands to navigate, create files, install tools, and run programs.

Git is a version control system that tracks changes to your code over time. GitHub is a platform built on Git that lets you store code online, collaborate with others, and manage projects.

Cloud computing is renting computing resources — servers, storage, databases, networking — from a provider like AWS, Azure, or GCP instead of buying and managing your own hardware.

Docker packages your application and all its dependencies into a container — a lightweight, portable unit that runs the same way on any machine. Containers solve the 'works on my machine' problem.

CI/CD (Continuous Integration / Continuous Deployment) automates the process of testing and deploying your code. Every time you push changes, a pipeline runs tests, builds the app, and deploys it — without manual steps.

Kubernetes (K8s) is an orchestration platform that manages containerised applications at scale. It handles deployment, scaling, load balancing, and self-healing across clusters of servers.

Infrastructure as Code (IaC) means defining your servers, networks, databases, and other resources in configuration files instead of setting them up manually. Tools like Terraform and Ansible make infrastructure reproducible and version-controlled.

Monitoring tracks the health and performance of your applications and infrastructure in real time. Logging captures detailed records of what happened, so you can debug issues after the fact.

Cloud security is the practice of protecting cloud-based applications, data, and infrastructure. It covers identity management, encryption, network security, compliance, and access control across cloud environments.
