Learn Cloud - Without Chasing a Certification¶
Plain-English explanations of cloud computing, networking, containers and DevOps for people who want to understand the technology, not just pass an exam.
Built and maintained by Patrick Wiloak - Ex-AWS Solutions Architect, 19x multi cloud certified, 64 certifications and accreditations, 10 years in tech. If certs aren't your goal, start here.

Who this is for¶
You want to understand cloud, but:
- You're not preparing for an exam (or not yet)
- You want context and intuition, not 200-question fact dumps
- You'd rather learn the why before drilling into vendor-specific details
- You're a developer, founder, PM, analyst, or curious technologist
If you do want certifications, head back to the Study Hub - every cloud cert on this site, fully indexed.
What's in this hub¶
Brand new to all of this?¶
- Day One - terminal, git, HTTP, servers. The pages assume nothing. If you've never opened a terminal, start here.
Bite-size concept pages¶
- Concepts - 18 topic pages, 5-10 min each. Cloud primitives (regions, VPC, K8s, serverless), DevOps (CI/CD, Terraform, deployment strategies), networking (DNS, CDNs, load balancing), and operations (autoscaling, caching, observability, cost).
Structured learning paths¶
- Cloud from Scratch - 8-phase path from "what is cloud?" to designing real systems
Learning AI, data or security?¶
- AI from Scratch on AI Zero to Hero - LLMs, RAG, agents, and production AI apps
- Data Zero to Hero - databases, pipelines, streaming and analytics
- Security Zero to Hero - identity, cloud security and compliance
Reference¶
- Glossary - cloud, DevOps and networking terms in plain English
- YouTube curation - filtered videos worth your time
How to use this¶
There's no "right order." Pick what fits:
| If you want to... | Start here |
|---|---|
| Start from absolute zero | Day One |
| Look up a term you keep seeing | Glossary |
| Understand one concept (VPC, DNS, containers, ...) | Concepts |
| Build a foundation in cloud | Cloud from Scratch |
| Compare AWS vs Azure vs GCP | Service comparisons |
| See real architectures | Architecture patterns |
| Try hands-on labs | Hands-on projects |
Why this exists¶
Most cloud content is either:
- Cert-shaped - exam objectives, fact sheets, practice questions (great if you have an exam date, useless if you just want to understand)
- Vendor marketing - "transform your business with the cloud!" (no actual technical content)
- Deeply specialized - PhD-level papers, engineering postmortems (skip the fundamentals you'd need to follow them)
This hub is the missing middle: technical, accurate, plain-English, no exam scaffolding.
Companion resources¶
- Main Study Hub - if you decide to certify
- Architecture Patterns - real-world multi-cloud patterns
- CLI Cheat Sheets - AWS, Azure, GCP, kubectl, Terraform, Docker, Helm, GitHub CLI
- Service Comparisons - cross-cloud equivalents
