Cloud engineers run infrastructure on cloud platforms. You will learn to provision compute, storage and networking, secure access, control cost and automate everything you repeat.
What the work looks like
You provision infrastructure with code, fix a failing deployment, review a security setting that is too open and check costs so nothing unexpected is running. Automation and careful permissions define the job.
Your learning plan
Timelines assume steady part-time study. Move on when you can do the checkpoints, not when the calendar says so.
Phase 1: Foundations (Weeks 1-5)
Linux, networking and how servers behave.
You are ready to move on when you can:
- Set up a Linux virtual machine and host a simple site on it
- Explain IP addresses, subnets and firewalls in plain language
Phase 2: One cloud provider (Weeks 6-10)
Learn the core services of AWS, Azure or Google Cloud.
You are ready to move on when you can:
- Deploy a web app using compute, storage and a managed database
- Set up users and roles with least privilege
Phase 3: Automation (Weeks 11-15)
Stop clicking, start scripting.
You are ready to move on when you can:
- Define an environment with Terraform and destroy and recreate it
- Containerise an app with Docker
Phase 4: Operations (Weeks 16-20)
Run it reliably and cheaply.
You are ready to move on when you can:
- Add monitoring, alerts and backups
- Set a budget alert and explain your cost decisions
Skills checklist
- Linux and networking fundamentals
- Pick one provider (AWS, Azure or GCP) and learn its core services
- Compute, storage, databases and identity and access management
- Docker and container basics
- Infrastructure as code, for example Terraform
- Monitoring, cost control and backup basics
- Consider the provider fundamentals certification
- Deploy a three-tier application end to end
Projects to build
- Static site on cloud storage with a CDN
- Web app on virtual machines with a managed database
- Terraform-managed environment
- Automated backup script
How to present your work
Draw the architecture, share the infrastructure code and explain the trade-offs. State what you would change for higher availability or lower cost. Always remove keys and account IDs before publishing.
What employers expect at entry level
A junior cloud engineer follows established patterns to deploy and maintain environments and raises concerns about cost and security early.
Free places to learn
Your chosen provider's free learning paths and documentation, the Terraform tutorials and Docker's getting-started guide. Course availability changes, so check each site for current content.
Common questions
Which cloud should I pick?
Choose the one most common in local job listings or your target company. Concepts transfer between providers, so depth in one is more valuable than shallow knowledge of three.
Will I be charged during practice?
Use free tiers carefully, set budget alerts on day one and delete resources when you finish each lab.
Are certifications required?
They help with screening but are not a substitute for building real environments.
Quick reference
Who is this career for?
People who like infrastructure, automation and understanding how large systems run.
Prerequisites
Basic Linux and networking knowledge.
Skills Required
One cloud platform, IAM, networking, containers, infrastructure as code, monitoring.
Tools
AWS, Azure or GCP free tiers, Terraform, Docker, the provider CLI.
Resume Strategy
Describe architectures you built, what services you used and how you secured them.
Interview Preparation
Expect questions on services you have used, IAM, high availability and how you would reduce cost.
Job Search Strategy
Apply for cloud support, junior cloud engineer and DevOps trainee roles; document your labs publicly.
Common Mistakes
Leaving resources running and paying for them; overly broad permissions; learning three clouds at once.
