Why Cloud Engineering?
The infrastructure skill set behind almost every modern product
Almost nothing ships on-prem anymore. Startups and enterprises alike run their applications on AWS, Azure, or Google Cloud, which means someone has to design the virtual networks, provision the compute and storage, lock down access, and keep the whole thing running without falling over — or blowing the budget. That's the Cloud Engineer: part infrastructure architect, part security-minded operator, fluent in the specific services of at least one major provider and the patterns (autoscaling, high availability, disaster recovery) that make cloud systems resilient.
It's a strong, durable career path precisely because cloud spend keeps growing and the skill gap hasn't closed — provider certifications (AWS, Azure, GCP) are some of the most recognized credentials in tech, and the role has real overlap with DevOps and Data Engineering once you add automation and pipelines into the mix. The roadmap below covers the core path: fundamentals first, then one provider deeply, then the security, automation, and cost-control layers that separate a working cloud setup from a production-grade one.

The Cloud Engineer Roadmap
Work through these in order. Each step has a short lesson, official docs, and a repo to practice in.
Cloud Computing Fundamentals
IaaS vs PaaS vs SaaS, public/private/hybrid deployment models, elasticity, and the shared responsibility model between you and your provider.
Networking Fundamentals
DNS, IP addressing and subnetting, virtual networks (VPC/VNet), load balancers, and CDNs — the plumbing every cloud service sits on top of.
Linux & Command Line Basics
Shell navigation, permissions, process management, and scripting — nearly every cloud instance you'll touch runs Linux under the hood.
Pick a Cloud Provider
Go deep on one major provider — AWS, Azure, or Google Cloud — and learn its console, CLI, resource hierarchy, and regions/availability zones.
Compute Services
Virtual machines (EC2, Azure VMs, Compute Engine), serverless functions (Lambda, Azure Functions, Cloud Functions), and when to pick each.
Storage & Databases
Object storage (S3, Blob Storage, Cloud Storage), block storage, and managed databases (RDS, Cloud SQL, DynamoDB) for different data needs.
Identity, Access & Security
IAM users, roles, and policies, the principle of least privilege, encryption at rest and in transit, and cloud-native security tooling.
Infrastructure as Code
Define and version your infrastructure instead of clicking through a console, with Terraform, AWS CloudFormation, or Azure Bicep/ARM.
Containers & Orchestration
Package applications with Docker and run them at scale with managed Kubernetes — EKS on AWS, AKS on Azure, or GKE on Google Cloud.
CI/CD & Automation
Automate builds, tests, and deployments with GitHub Actions, GitLab CI, Jenkins, or provider-native pipelines like AWS CodePipeline.
Monitoring & Logging
Track health and performance with CloudWatch, Azure Monitor, or Grafana/Prometheus, and centralize logs so incidents are fast to diagnose.
Cost Optimization & Certifications
Right-sizing, reserved/spot instances, tagging for cost visibility, and provider certifications (AWS Solutions Architect, Azure Administrator, GCP ACE) to validate what you've learned.
GitHub Projects
Real, buildable projects to put on your own GitHub
Provisioned VPC & Compute
Use Terraform to stand up a VPC, subnets, and an EC2 instance, then tear it all down cleanly with a single command.
Kubernetes the Hard Way
Build a Kubernetes cluster from scratch, node by node, to understand exactly what a managed service like EKS is doing for you.
Serverless Application
Deploy a full serverless app using Lambda, API Gateway, and DynamoDB to see event-driven architecture in practice.
Cloud Monitoring Stack
Deploy Prometheus and Grafana against a cloud workload and build a dashboard that tracks real infrastructure metrics.
Track complete
Twelve steps, from cloud fundamentals to cost-optimized, certified infrastructure. Push what you built to GitHub so it's visible to employers, then keep going — cloud is learned by provisioning real infrastructure, not just reading service docs.
