Step 1

Foundational Workflow & OS

Before automating, you must master the environment. DevOps starts with the Command Line Interface (CLI) and an absolute understanding of how Linux processes, permissions, and networking function.

🐧 Linux Mastery

Master Bash scripting, Vim/Nano, SSH, Systemd, and Process Management. Linux is the backbone of the cloud.

🌿 GitOps & Branching

Understand Trunk-Based Development vs GitFlow. Learn how to manage merge conflicts and maintain a clean commit history.

🐚 Scripting & Automation

Automate repetitive tasks using Python, Go, or Bash. If you have to do it twice, you should script it.

🌐 Networking Basics

OSI Model, DNS, HTTP/HTTPS, FTP, SSL/TLS, and basic firewall configurations (UFW/IPTables).

Step 2

CI/CD: Continuous Everything

Automating the build, test, and deployment phases reduces human error and accelerates time-to-market. This is the "Engine Room" of modern software delivery.
Integration

πŸ”„ GitHub Actions

Build workflows directly in your repository. Master triggers, secrets, and reusable actions for automated testing.

Automation

πŸ—οΈ Jenkins Pipelines

Learn the industry standard for self-hosted CI/CD. Understand Jenkinsfiles (Groovy), master-agent architecture, and plugins.

Delivery

πŸš€ GitLab CI

Explore integrated CI/CD solutions. Learn about runners, .gitlab-ci.yml configuration, and environments.

Deployment

βš“ ArgoCD (GitOps)

Move towards declarative continuous delivery for Kubernetes. Ensure your cluster state always matches your Git repo state.

Step 3

Containers & Orchestration

Containers ensure consistency across development, staging, and production. Orchestration allows you to manage these containers at a massive scale across clusters of servers.

🐳 Docker Essentials

Learn to write efficient Dockerfiles. Master multi-stage builds, networking, volumes, and Docker Compose for local dev.

☸️ Kubernetes (K8s)

Understand Pods, Services, Deployments, and Ingress. Learn how to scale and manage self-healing applications.

πŸ“¦ Helm Charts

The package manager for Kubernetes. Simplify the deployment of complex applications using templates and versioned charts.

πŸ•ΈοΈ Service Mesh (Istio)

Manage service-to-service communication. Learn about traffic splitting, mTLS security, and observability in a microservices mesh.

πŸ–ΌοΈ Container Registries

Manage and secure your images. Learn about Harbor, Docker Hub, and cloud-native registries (AWS ECR / Google Artifact Registry).

Step 4

Infrastructure as Code (IaC)

Treat your infrastructure like software. Version it, review it, and deploy it automatically. This eliminates "Snowflake Servers" and ensures environment parity.
Provisioning

πŸ—οΈ Terraform

Master HCL (HashiCorp Configuration Language). Provision infrastructure across multiple cloud providers using a single workflow.

Configuration

πŸ“œ Ansible

Agentless configuration management. Learn to automate server setup, application deployment, and system updates via SSH.

Cloud-Native

☁️ Pulumi

Define infrastructure using familiar programming languages like Python, TypeScript, or Go instead of DSLs like YAML or HCL.

Immutable

🧱 Packer

Create identical machine images (AMIs) for multiple platforms from a single source configuration. Perfect for building golden images.

Step 5

Observability & SRE

You cannot improve what you cannot measure. Observability is about understanding the internal state of a system by looking at the data it produces (Logs, Metrics, Traces).

πŸ“ˆ Prometheus & Grafana

Scrape time-series metrics using Prometheus and visualize them by building powerful, real-time Grafana dashboards.

πŸͺ΅ ELK / EFK Stack

Centralized logging. Master Elasticsearch, Logstash/Fluentd, and Kibana to search through terabytes of logs in seconds.

πŸ” OpenTelemetry & Tracing

Track requests as they travel through microservices using Distributed Tracing tools like Jaeger or Zipkin.

πŸ’₯ Chaos Engineering

Break things on purpose. Use tools like Chaos Mesh or Gremlin to test system resilience under simulated failure conditions.

Step 6

Cloud Architecture

The physical servers are gone. Modern DevOps requires deep knowledge of at least one major public cloud provider's ecosystem.
Market Leader

☁️ Amazon Web Services (AWS)

Learn the core trinity: EC2 (Compute), S3 (Storage), and VPC (Networking). Expand into IAM, RDS, and EKS.

Enterprise

πŸ’Ό Microsoft Azure

Highly integrated with enterprise Microsoft environments. Focus on Azure DevOps, Azure Kubernetes Service (AKS), and Entra ID.

Data-Centric

πŸ“Š Google Cloud Platform (GCP)

The birthplace of Kubernetes. Excellent for data analytics and ML. Master GKE, BigQuery, and Cloud Run.

Serverless

⚑ Serverless Computing

Focus entirely on code. Learn AWS Lambda, Azure Functions, or Google Cloud Functions for event-driven architectures.

DevOps Terminology Glossary

The language of Site Reliability

CI/CD
Continuous Integration (merging code frequently) and Continuous Deployment (releasing to production automatically).
SRE
Site Reliability Engineering. Applying software engineering practices to IT operations problems.
SLI, SLO, SLA
Indicators (metrics), Objectives (internal goals), and Agreements (external contracts) for service reliability.
Immutable Infrastructure
Servers that are never modified after deployment. If a change is needed, a new server is deployed.
Blue/Green Deployment
Running two identical production environments to switch traffic seamlessly with zero downtime.
Canary Release
Rolling out a new feature to a small percentage of users before a full deployment to monitor for errors.
