Roadmap

Phase 1: Foundations (Pre-DevOps Skills)

Before diving into DevOps tools, you need strong basics:

  1. OS & Networking

    • Linux commands, file permissions, processes

    • Networking basics: TCP/IP, DNS, HTTP/S, SSH, firewalls

    • System monitoring tools (top, netstat, lsof, etc.)

  2. Programming/Scripting

    • Pick one scripting language (Python, Bash, Go)

    • Learn to write automation scripts

  3. Version Control

    • Git fundamentals (branching, merging, rebasing, tags)

    • GitHub/GitLab workflows (PRs, code reviews)

🟡 Phase 2: Core DevOps Skills

Here’s where the real journey begins:

  1. CI/CD (Continuous Integration & Delivery)

    • Jenkins, GitHub Actions, GitLab CI, CircleCI

    • Build pipelines, testing automation, deployments

  2. Configuration Management

    • Tools: Ansible, Puppet, Chef, SaltStack

    • Write playbooks, manage infra as code

  3. Containers & Orchestration

    • Docker (images, volumes, networks)

    • Kubernetes (pods, services, deployments, scaling)

    • Helm for package management

  4. Infrastructure as Code (IaC)

    • Terraform (providers, modules, state management)

    • CloudFormation (if AWS focused)

🔵 Phase 3: Cloud & Scaling

Most DevOps happens in the cloud:

  1. Cloud Platforms

    • AWS, Azure, or GCP (pick one, then expand)

    • Core services: EC2/VMs, Networking, IAM, Load Balancers, Databases, Storage

    • Advanced: Lambda (serverless), Kubernetes in cloud (EKS/AKS/GKE)

  2. Monitoring & Logging

    • Prometheus + Grafana

    • ELK/EFK stack

    • CloudWatch, Datadog, New Relic

  3. Security (DevSecOps)

    • Secrets management (Vault, SSM Parameter Store)

    • Static code analysis (SonarQube, Snyk)

    • Secure Docker images, vulnerability scanning

🟣 Phase 4: Advanced DevOps & SRE

When you’re comfortable with the above, move to mastery:

  1. Site Reliability Engineering (SRE)

    • SLIs, SLOs, SLAs

    • Error budgets, reliability patterns

    • Chaos engineering

  2. Advanced Automation

    • GitOps (ArgoCD, Flux)

    • Policy as Code (OPA, Kyverno)

  3. Scalability & Performance

    • Load balancing, auto-scaling

    • Distributed systems basics

    • Caching strategies (Redis, Memcached)

⚫ Phase 5: Continuous Learning & Mastery

  • Contribute to open-source DevOps projects

  • Stay updated with CNCF projects (new tools like Crossplane, Dapr, etc.)

  • Get certifications if needed (AWS DevOps Pro, CKA, Terraform Associate)

  • Mentor juniors & build projects (your own CI/CD pipeline, infra automation, monitoring stack)
