What does this role do?

DevOps Engineers bridge the gap between development and operations. They design and own the systems that take code from a developer's laptop to a production server reliably and repeatedly.

  • Design and maintain CI/CD pipelines
  • Containerize applications with Docker and Kubernetes
  • Provision and manage cloud infrastructure with Terraform
  • Set up monitoring, alerting, and on-call workflows
  • Automate repetitive operational tasks using scripts and pipelines
  • Collaborate with dev and SRE teams on production readiness

Industry Context

DevOps Engineers are among the most in-demand roles across startups, scale-ups, and enterprises. They appear in product teams, platform teams, and dedicated DevOps centers of excellence.

In Azure-heavy shops, they work extensively with AKS, Azure DevOps, and Bicep. In multi-cloud environments, they own Terraform and cross-cloud deployment pipelines.

  • Found in SaaS companies, banks, healthcare, and e-commerce
  • Often the first hire after a startup reaches production scale
  • Progression path: Junior DevOps → Senior → Platform Engineer / Architect

Your 10-Step Roadmap

Follow this path in order. Each step builds on the previous one. Complete all 10 to be job-ready.

01
🐧 LinuxFoundation

Every server runs Linux. Master the command line, file systems, permissions, networking, process management, and systemd. Without this, nothing else works.

02
🐙 GitHub FundamentalsVersion Control

Learn Git branching, pull requests, merge strategies, and team collaboration workflows. Version control is the foundation of every CI/CD pipeline.

03
🐳 DockerContainers

Build, ship, and run containers. Dockerfile best practices, multi-stage builds, volumes, networking, and container security essentials.

04
☸️ KubernetesOrchestration

Orchestrate containers at scale. Pods, deployments, services, ingress, RBAC, autoscaling, and production troubleshooting patterns.

05
⎈ HelmPackage Management

Package and manage Kubernetes applications with Helm charts. Templating, values, hooks, chart libraries, and release lifecycle management.

06
⚡ GitHub ActionsCI/CD

Automate builds, tests, and deployments with GitHub Actions. YAML workflows, secrets management, OIDC, reusable workflows, and AKS deployments.

07
🏗️ TerraformIaC

Provision and manage cloud infrastructure as code. State management, modules, workspaces, Azure provider, and CI/CD-integrated deployments.

08
☁️ Azure BasicsCloud

Understand the Azure platform: resource hierarchy, subscriptions, IAM, ARM, billing, and the core services DevOps engineers depend on daily.

09
📊 Prometheus & GrafanaMonitoring

Build a complete observability stack. Prometheus metrics collection, PromQL queries, Alertmanager, and Grafana dashboards for production systems.

10
🛠️ SRE ConceptsReliability

Adopt SRE principles: SLIs, SLOs, error budgets, incident response, blameless postmortems, and chaos engineering for production reliability.

What You'll Actually Build

Zero-Downtime Deployment Pipeline

Build a GitHub Actions pipeline that builds a Docker image, scans it, pushes to ACR, and deploys to AKS with a rolling update — all on every pull request merge.

Cloud Infrastructure Automation

Define an entire Azure environment (VNet, AKS, Key Vault, Storage) in Terraform, commit it to GitHub, and let a pipeline apply it automatically on every merge to main.

Production Observability Stack

Deploy Prometheus and Grafana on Kubernetes, configure exporters for your application, build dashboards for p95 latency and error rates, and set up PagerDuty-connected alerts.
