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
