DevOps Engineer Roadmap 2026

Stage 1: Linux and Networking Fundamentals (3-4 weeks)

1. The Linux filesystem, permissions, and core CLI tools
2. Process management and systemd basics
3. Core networking concepts -- DNS, HTTP, TCP/IP, load balancing
4. Example: set up and secure a fresh Linux VPS from scratch, by hand, before automating any of it

Stage 2: Scripting and Version Control (2 weeks)

1. Bash scripting for automation tasks
2. Python basics for more complex tooling scripts
3. Git workflows -- branching, merging, pull requests
4. Example: write a bash script that automates the manual server setup from Stage 1

Stage 3: Containers (3-4 weeks)

1. Docker -- images, containers, Dockerfiles, multi-stage builds
2. Docker Compose for local multi-container development
3. Container registries and image versioning
4. Example: containerize a real application (even a simple one) with a proper multi-stage Dockerfile

Stage 4: CI/CD (2-3 weeks)

1. CI/CD concepts -- build, test, deploy pipelines
2. A tool like GitHub Actions, GitLab CI, or Jenkins
3. Automated testing as a pipeline gate
4. Example: set up a pipeline that automatically builds, tests, and deploys the containerized app from Stage 3 on every push

Stage 5: Orchestration and Infrastructure as Code (4-6 weeks)

1. Kubernetes fundamentals -- pods, deployments, services, scaling
2. Terraform for provisioning cloud infrastructure declaratively
3. Configuration management concepts (Ansible or similar)
4. Example: deploy the app to a managed Kubernetes cluster, with its infrastructure defined in Terraform

Stage 6: Monitoring and Cloud Platform (3-4 weeks)

1. Deep expertise in one cloud provider (AWS, Azure, or GCP)
2. Monitoring and alerting -- Prometheus and Grafana, or a cloud-native equivalent
3. Centralized logging
4. Example: add monitoring dashboards and alerts for the deployed app's health and resource usage
