Phase 1: Foundations — Linux, Networking & Git

Every DevOps journey begins with a firm grasp of operating systems and networking. You cannot automate, containerize, or orchestrate what you do not fundamentally understand.

Linux

Linux is the dominant server OS in the cloud-native world. A DevOps engineer must be comfortable navigating the terminal, managing processes, and configuring services. Key topics include:

  • File system hierarchy — /etc, /var, /proc, /home
  • Process management — ps, top, systemctl, kill
  • User & permissions — chmod, chown, sudo, PAM
  • Package management — apt, yum, dnf
  • Shell environments — bash, zsh, environment variables

Networking Fundamentals

Understanding how systems communicate is essential for troubleshooting and designing distributed architectures:

LayerTopicKey Concepts
L3IP AddressingCIDR, subnets, NAT
L4TransportTCP/UDP, ports, handshakes
L7ApplicationHTTP/HTTPS, DNS, TLS
SecurityFirewallsiptables, security groups, NACLs

Version Control with Git

Git is the backbone of DevOps workflows. Every infrastructure change, pipeline definition, and application config should live in a Git repository — a practice known as GitOps .

Core skills: commit, branch, merge, rebase, pull request workflows, and resolving merge conflicts.

Don't Skip the Fundamentals

Many learners rush to learn Kubernetes or Terraform before understanding Linux and networking. This creates fragile knowledge — you'll struggle to debug pods that can't reach each other if you don't understand DNS resolution, CIDR blocks, or TCP handshakes. Invest in foundations first; every advanced tool builds on these concepts.

Phase 2: Programming & Scripting

DevOps is fundamentally about automation, and automation requires code. You need at least one scripting language and solid Bash skills.

Python — The DevOps Lingua Franca

Python dominates the DevOps tooling ecosystem. Tools like Ansible, AWS CLI, and the Kubernetes Python client are all built with Python. Focus areas:

  • Core syntax, data structures (lists, dicts, sets)
  • File I/O and working with JSON/YAML
  • REST API interactions with requests
  • Automation scripts for system administration
  • Error handling and logging

Bash Scripting

Bash remains critical for day-to-day operations. Write scripts for:

  • Log parsing and analysis
  • Automated backup and cleanup routines
  • Health check and monitoring probes
  • Deployment helper scripts

Go (Optional but Powerful)

Many cloud-native tools (Kubernetes, Terraform, Docker) are written in Go. Learning Go helps you understand these tools' internals and contribute to open-source projects.

Build Your First Automation Script

  1. 1
    Step 1

    Pick a manual task you perform regularly — e.g., cleaning up old Docker images, rotating application logs, or checking SSL certificate expiry dates.

  2. 2
    Step 2

    Use Python with os, subprocess, requests, or boto3 to automate the task. Include proper error handling with try/except blocks and logging with the logging module.

  3. 3
    Step 3

    Use argparse to make your script configurable — accept parameters like --days, --environment, or --dry-run for flexibility.

  4. 4
    Step 4

    Deploy the script to a Linux server and schedule it with crontab. Example: 0 2 * * * /usr/local/bin/cleanup.py --days 30 runs nightly at 2 AM.

  5. 5
    Step 5

    Redirect output to a log file, or integrate with a monitoring system. Verify the script runs correctly by checking logs after the first scheduled execution.

Phase 3: Cloud Platforms

Cloud computing is the foundation on which modern DevOps practices are built. A Cloud Platform provides the infrastructure that IaC provisions, containers orchestrate, and pipelines deploy to.

The Big Three: AWS, Azure, GCP

FeatureAWSAzureGCP
Market Share (2024)~31%~24%~11%
StrengthMaturity, ecosystemEnterprise integrationData, AI/ML, open-source
IaC ServiceCloudFormationARM TemplatesDeployment Manager

Entry-Level Cert Cost$100$99$99
DevOps CertDevOps Engineer ProDevOps Engineer ExpertCloud DevOps Engineer
Certified Avg Salary~$160,000~$140,000~$155,000

Recommendation: Start with one cloud platform and go deep. AWS has the largest market share and job market, but Azure is growing faster, especially in enterprise 2. Choose based on your local job market.

Core Services to Learn

Regardless of the platform, master these categories:

  1. Compute — EC2/VMs, Serverless (Lambda/Functions)
  2. Storage — S3/Blob/GCS, EBS/Managed Disks
  3. Networking — VPC/VNet, Subnets, Load Balancers, DNS
  4. Identity — IAM, RBAC, Service Accounts
  5. Databases — RDS/Cloud SQL, DynamoDB/CosmosDB

Phase 4: Containers & Orchestration

Containerization has become the mainstream method of building and deploying applications, allowing software to be packaged with all its dependencies .

Docker — The Container Standard

Docker provides isolated, reproducible environments. Key concepts:

  • Images & Containers — Build, tag, push, pull
  • Dockerfile — FROM, RUN, COPY, ENTRYPOINT, multi-stage builds
  • Volumes — Persistent data management
  • Networking — Bridge, host, overlay networks
  • Docker Compose — Multi-container local development

Kubernetes — Production Orchestration

Kubernetes is the de facto standard for running containers in production. It manages resource provisioning, container scheduling, grouping, and coordination .

Core K8s Concepts

ConceptPurpose
PodSmallest deployable unit; one or more containers
DeploymentDeclarative updates for Pods; manages ReplicaSets
ServiceStable network endpoint for a set of Pods
ConfigMap / SecretExternal configuration and sensitive data
IngressHTTP routing and TLS termination
NamespaceLogical cluster partitioning
HelmPackage manager for templated K8s deployments

  2. AWS — Terraform vs Kubernetes: The Difference - Technical comparison clarifying that Terraform provisions infrastructure while Kubernetes orchestrates containers. ↩

1# Multi-stage Dockerfile
2FROM node:20-alpine AS builder
3WORKDIR /app
4COPY package*.json ./
5RUN npm ci --only=production

7FROM node:20-alpine
8WORKDIR /app
9COPY --from=builder /app/node_modules ./node_modules
10COPY . .
11EXPOSE 3000
12CMD ["node", "server.js"]

Kubernetes Learning Strategy

Don't try to learn every K8s resource type at once. Start with Pods, Deployments, and Services — they cover 80% of production use cases. Add ConfigMaps, Secrets, and Ingress next. Only then move to advanced topics like Custom Resource Definitions (CRDs), Operators, and Service Mesh. Use a local cluster tool like minikube or kind for hands-on practice.

Phase 5: CI/CD — Continuous Integration & Continuous Delivery

CI/CD is the engine that drives the DevOps lifecycle. CI ensures every code change is automatically built and tested; CD extends this to automated deployment .

CI/CD Pipeline Architecture

CI/CD Tool Comparison

ToolTypeStrengthsBest For
JenkinsSelf-hostedMassive plugin ecosystem, matureComplex enterprise pipelines
GitHub ActionsSaaS/Self-hostedNative GitHub integration, YAML-basedOpen-source & GitHub projects
GitLab CISelf-hosted/SaaSAll-in-one DevOps platformComplete DevOps lifecycle
ArgoCDSelf-hostedGitOps-native, K8s-focusedKubernetes GitOps workflows
CircleCISaaSFast parallel builds, Docker supportFast iteration teams

Jenkins still leads the CI/CD tool market with a 46.35% share, though newer tools like GitHub Actions are rapidly gaining ground .

Phase 6: Infrastructure as Code & Configuration Management

IaC eliminates manual setup, ensures consistency, and makes infrastructure version-controllable and auditable .

Terraform vs. Ansible — Different Jobs

AspectTerraformAnsible
PurposeInfrastructure provisioningConfiguration management
ApproachDeclarativeImperative/Procedural
StateMaintains state fileStateless
LanguageHCLYAML playbooks
ScopeCloud resources (VPCs, VMs, DBs)OS-level config (packages, files, services)
Best PracticeCreates the infrastructureConfigures what runs on it

Terraform manages the "what" (the infrastructure), while Ansible handles the "how" (the software running on it). This separation of concerns produces a predictable, automated, and scalable deployment process .

Key Terraform Concepts

  • Providers — AWS, Azure, GCP, Helm, Kubernetes
  • Resources — Individual infrastructure objects
  • Modules — Reusable, parameterized packages of resources
  • State — Tracks real-world resources vs. desired config
  • Workspaces — Environment separation (dev/staging/prod)

  2. Group107 — DevOps Tools Comparison for Modern Enterprises - Details on the Terraform/Ansible separation of concerns and container orchestrator capabilities. ↩

Deploy a Production-Like Environment with IaC

  1. 1
    Step 1

    Write Terraform modules for VPC, subnets, security groups, and compute instances. Use remote state (S3 + DynamoDB lock) for team collaboration. Organize code with environments/ and modules/ directory structure.

  2. 2
    Step 2

    Write Ansible playbooks to install Docker, deploy your application containers, configure Nginx as a reverse proxy, and set up log rotation. Use Ansible vault for secrets.

  3. 3
    Step 3

    Add terraform plan and terraform apply stages to your CI/CD pipeline. Always apply IaC through CI/CD — never manually from the console — to prevent configuration drift.

  4. 4
    Step 4

    Use tools like OPA/Conftest or Checkov to validate Terraform plans before apply. Enforce policies like 'no public S3 buckets' and 'all EBS volumes must be encrypted.'

  5. 5
    Step 5

    Run terraform validate and tflint in CI. Use tools like Terratest to write integration tests that verify your infrastructure behaves as expected.

Phase 7: Monitoring, Observability & Reliability

You cannot operate what you cannot see. Observability extends beyond traditional monitoring by combining three pillars: metrics, logs, and distributed traces.

The Three Pillars

PillarTool ExamplesPurpose
MetricsPrometheus, CloudWatchQuantitative measurements over time (CPU, latency, request count)
LogsELK Stack, Loki, SplunkDiscrete event records for debugging
TracesJaeger, Tempo, OpenTelemetryRequest flow across distributed services

Key Monitoring Metrics

  • Infrastructure: CPU utilization, memory usage, disk I/O, network throughput
  • Application: Response times, error rates, throughput, user sessions
  • Business: Conversion rates, revenue impact, user satisfaction scores

SRE Fundamentals

Site Reliability Engineering (SRE) provides the theoretical framework:

  • SLI (Service Level Indicator) — A quantitative measure (e.g., 99.9% request success rate)
  • SLO (Service Level Objective) — The target value for an SLI (e.g., 99.9% availability)
  • SLA (Service Level Agreement) — The contractual commitment with consequences
  • Error Budget — 1−SLO1 - \text{SLO}, the acceptable failure rate within a time window

Error Budget=1−SLO\text{Error Budget} = 1 - \text{SLO}

For a 99.9% SLO over 30 days: Allowed Downtime=30×24×60×(1−0.999)=43.2 minutes\text{Allowed Downtime} = 30 \times 24 \times 60 \times (1 - 0.999) = 43.2 \text{ minutes}

Phase 8: DevSecOps — Security as Code

DevSecOps shifts security left — embedding it into every stage of the software delivery lifecycle .

Security Integration Points

Essential Security Tools

  • SAST — SonarQube, Semgrep (code-level vulnerabilities)
  • SCA — Snyk, Dependabot (dependency vulnerabilities)
  • Container Scanning — Trivy, Aqua Security
  • IaC Scanning — Checkov, tfsec, Terrascan
  • Secrets Detection — GitLeaks, TruffleHog
  • Policy-as-Code — OPA (Open Policy Agent), Kyverno
