DevOps Engineer Roadmap 2025

Master CI/CD, containers, cloud platforms, and infrastructure automation. From Linux basics to Kubernetes and monitoring.

🏗️Fundamentals

1

Linux & Operating Systems

The foundation of server infrastructure.

  • Linux command line (bash, file system, permissions)
  • Shell scripting
  • Process management (systemd, cron)
  • Networking (SSH, firewall, ports)
  • Package managers (apt, yum, brew)
2

Networking

Understand how networks work.

  • TCP/IP, UDP, and DNS
  • HTTP/HTTPS and TLS/SSL
  • Load balancing concepts
  • Firewalls and security groups
  • CDNs and edge computing
3

Version Control

Git mastery is essential.

  • Git branching strategies (GitFlow, trunk-based)
  • Pull requests and code reviews
  • Git hooks and automation
  • Monorepo management

🐳Containers & Orchestration

4

Docker

Containerize everything.

  • Dockerfiles (multi-stage builds)
  • Docker Compose
  • Image registries (Docker Hub, ECR, GCR)
  • Container security and best practices
  • Docker networking and volumes
5

Kubernetes

Orchestrate containers at scale.

  • Pods, Deployments, Services
  • ConfigMaps and Secrets
  • Ingress controllers
  • Helm charts
  • Horizontal Pod Autoscaler
  • Managed K8s (EKS, GKE, AKS)

🔄CI/CD

6

CI/CD Pipelines

Automate build, test, and deploy.

  • GitHub Actions (recommended)
  • GitLab CI/CD
  • Jenkins (enterprise)
  • Build automation (lint, test, build, deploy)
  • Artifact management
  • Deployment strategies (blue-green, canary, rolling)

☁️Cloud & Infrastructure

7

Cloud Platforms

Learn at least one cloud provider.

  • AWS (most popular — EC2, S3, RDS, Lambda)
  • Google Cloud (GKE, Cloud Run, BigQuery)
  • Azure (enterprise — VMs, App Service)
  • Cloud networking (VPC, subnets, security groups)
8

Infrastructure as Code

Manage infrastructure programmatically.

  • Terraform (recommended)
  • Pulumi (infrastructure as real code)
  • AWS CloudFormation
  • Ansible for configuration management

📊Monitoring & Observability

9

Monitoring Stack

Know what's happening in production.

  • Metrics (Prometheus, Grafana)
  • Logging (ELK Stack, Loki)
  • Tracing (Jaeger, OpenTelemetry)
  • Alerting and on-call (PagerDuty, OpsGenie)
  • APM (Datadog, New Relic)
  • Uptime monitoring
