Are you curious about DevOps, overwhelmed by all the tools, or simply don’t know where to begin? This guide is crafted for absolute beginners—those who are new to tech or just getting started in software development, operations, or system administration.
By the end of this guide, you’ll have a crystal-clear path to mastering DevOps and becoming job-ready—even if you're starting with zero experience.
What is DevOps?
DevOps is a combination of Development and Operations. It's not just a tool or a job title—it's a culture that promotes collaboration between developers and IT operations teams, focusing on automation, efficiency, and continuous delivery.
Key Benefits of DevOps
Faster software releases
Improved collaboration
Greater automation and fewer errors
Scalable and reliable infrastructure
DevOps Lifecycle Overview
Understanding the DevOps lifecycle is the first step toward becoming a pro:
Plan – Define features, requirements, and timelines.
Develop – Code the application.
Build – Compile and package the application.
Test – Automatically test the code for bugs.
Release – Make the app available to users.
Deploy – Push the app to servers or containers.
Operate – Maintain app availability and performance.
Monitor – Track logs, metrics, and user behavior.
Step-by-Step DevOps Learning Roadmap
Here’s how you go from zero to hero, broken down by stages.
Stage 1: Learn the Basics (Weeks 1–4)
Linux and Terminal
Commands: ls, cd, cat, grep, chmod
Scripting: Bash basics
Resources:
Linux Journey
Nile Bits - Terminal Productivity
Git and Version Control
Core commands: git clone, commit, push, branch, merge
GitHub for hosting
Resources:
Git Handbook by GitHub
Stage 2: Automate Everything (Weeks 5–8)
Continuous Integration / Continuous Deployment (CI/CD)
Learn tools like Jenkins, GitHub Actions, or GitLab CI/CD
Build pipelines to automate code testing and deployments
Jenkinsfile Example:
pipeline {
agent any
stages {
stage('Build') {
steps { echo 'Building...' }
}
stage('Test') {
steps { echo 'Testing...' }
}
stage('Deploy') {
steps { echo 'Deploying...' }
}
}
}

Stage 3: Learn Infrastructure as Code (Weeks 9–12)
Terraform
Define and provision infrastructure using code
Example:
provider "aws" {
region = "us-east-1"
}
resource "aws_instance" "web" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
}

Stage 4: Master Containers and Orchestration (Weeks 13–16)
Docker
Create lightweight, portable application containers
Dockerfile Example:
FROM node:18
WORKDIR /app
COPY . .
RUN npm install
CMD ["node", "index.js"]
Kubernetes
Manage containers at scale with orchestration

Stage 5: Monitoring and Logging (Weeks 17–20)
Tools:
Prometheus + Grafana – For metrics
ELK Stack – For centralized logging
