For beginners: cloud fundamentals and a first certification
These three courses cover the same foundational territory — cloud concepts, core services, pricing, security — but each is optimized for a different provider path.
What you’ll learn
- Cloud concepts, AWS global infrastructure, and core services (EC2, S3, RDS, Lambda)
- Security, compliance, the shared responsibility model, and IAM basics
- AWS pricing models, support plans, and billing tools
Why we picked it: the most recommended entry-level cloud computing course on Reddit, period. Maarek updates it within weeks of any AWS exam change. If you’re starting from zero, this is the one.
What you’ll learn
- Cloud concepts and the shared responsibility model
- Azure core services: compute, networking, storage, databases
- Azure pricing, SLAs, and the service lifecycle
Why we picked it: the top-rated AZ-900 prep course on Udemy, consistently praised for clarity and exam alignment. Ideal for IT professionals already working in Microsoft environments who want to formalize their cloud training.
What you’ll learn
- Cloud fundamentals and Google Cloud’s core product categories
- Digital transformation concepts and business use cases
- An overview of the data and AI products (BigQuery, Vertex AI)
Why we picked it: the best free entry point for GCP beginners — official content, no paywalls, and directly aligned to the Digital Leader exam. A solid first course before committing to a paid path.
For developers: building on the cloud
Once you have a foundational cert, the developer track shifts focus — building and deploying applications, not just understanding services.
What you’ll learn
- Serverless architecture: Lambda, API Gateway, DynamoDB, SQS/SNS
- CI/CD pipelines: CodePipeline, CodeBuild, CodeDeploy
- S3, IAM, CloudWatch, X-Ray, and Elastic Beanstalk
Why we picked it: the best cloud course for developers building serverless and cloud-native applications on AWS. It covers the full developer workflow end-to-end, not just the exam objectives.
What you’ll learn
- Azure Functions, Logic Apps, and event-driven architecture
- Cosmos DB, App Service, Azure Storage, and API Management
- Authentication, authorization, and Azure Key Vault
Why we picked it: the standard AZ-204 prep for developers in the Microsoft ecosystem. A Cloud Guru’s lab environment lets you practice directly in Azure without managing your own subscription costs.
What you’ll learn
- Cloud Run, GKE, and container-native deployment
- Pub/Sub, Cloud SQL, Firebase, and Cloud Spanner
- CI/CD with Cloud Build, Artifact Registry, and Cloud Deploy
Why we picked it: the best path for developers targeting GCP and Kubernetes-native applications. If you’re building microservices or event-driven systems, GCP’s developer track is genuinely strong.
For DevOps and cloud engineers: infrastructure and automation
This is where cloud training gets serious. These courses target the credentials hiring managers actually filter for.
What you’ll learn
- EC2, S3, RDS, Aurora, VPC, Route 53, and CloudFront
- IAM, KMS, CloudFormation, EKS, ECS, and auto-scaling
- High availability, disaster recovery, and cost optimization patterns
Why we picked it: the most employer-recognized cloud architecture credential at associate level. SAA-C03 is the single cert that appears most often in cloud engineer and solutions architect job postings — non-negotiable for anyone serious about cloud infrastructure.
What you’ll learn
- Azure VMs, virtual networks, load balancers, and VPN gateways
- Azure Active Directory, RBAC, and identity management
- Storage accounts, Azure Monitor, and backup/recovery
Why we picked it: the standard Azure admin certification for cloud engineers in Microsoft environments. AZ-104 is the natural next step after AZ-900, and the baseline requirement for most Azure cloud engineer roles.
What you’ll learn
- Infrastructure as code fundamentals and HCL syntax
- Terraform modules, state management, and remote backends
- Multi-cloud provisioning across AWS, Azure, and GCP
Why we picked it: the most in-demand IaC certification across all three providers. Terraform is the lingua franca of cloud infrastructure automation — this cert signals multi-cloud fluency and is increasingly listed as a requirement in DevOps and platform engineering roles.
For data engineers and AI practitioners
Cloud classes for data roles have a different center of gravity: managed data services, streaming pipelines and ML infrastructure matter more than raw compute.
What you’ll learn
- BigQuery: data modeling, partitioning, and query optimization
- Dataflow (Apache Beam), Pub/Sub, and Cloud Storage
- Vertex AI, ML pipelines, and model deployment on GCP
Why we picked it: GCP’s data engineering certification is the strongest cloud credential for data-heavy roles. BigQuery and Dataflow are used at scale by companies like Spotify and Airbus — this cert proves you can work at that level.
Structured cloud training with real instructor mentorship, covering end-to-end data pipelines and cloud infrastructure across AWS and GCP. Projects are built on real cloud environments — not sandboxes.
Why we picked it: the structured alternative to self-paced courses for learners who want accountability and feedback rather than another certificate.
Best Free Cloud Computing Courses and Resources
Paid courses aren’t the only way to learn cloud. These four free options are genuinely useful — with honest notes on where each falls short.
| Resource | What you get | Where it falls short |
|---|---|---|
| AWS Skill Builder (free tier) | 600+ free digital courses, official AWS content, and CLF-C02 prep modules | No hands-on lab access without an Individual subscription (~$29/month) — good for theory, limited for practice |
| Microsoft Learn | The complete AZ-900 learning path, free, official and well-structured — Azure fundamentals end to end | Nothing significant: no subscription required, one of the best free cloud resources available |
| Google Cloud Skills Boost (free tier) | The Digital Leader course free, plus $300 in credits for new accounts to run real labs | Deeper professional tracks move behind a subscription — but the free tier is more generous than AWS or Azure |
| Cloud Computing Specialization (U. of Illinois) | Distributed systems, cloud architecture, MapReduce and Spark — rigorous university-level content, free to audit | Academic rather than provider-specific: complements certification prep, doesn’t replace it |

CLF-C02 → SAA-C03 → Terraform Associate. That combination covers AWS architecture, multi-cloud infrastructure as code, and signals genuine cloud engineering depth to hiring managers — for roughly $50 in course costs plus exam fees.
Cloud Computing Career Paths and Salaries in 2026
Cloud certifications unlock some of the highest-paying roles in tech. Here’s where the market sits in 2026 (US base salary ranges).
One more role rounds out the market: Site Reliability Engineer (SRE) at $110K–$165K, focused on availability, observability and incident response.
Professionals certified on two or more providers (AWS + Azure, or AWS + GCP) consistently earn 15–25% more than single-cloud peers. Early in your cloud career, the fastest path to the top of these ranges is: one foundational cert → one associate cert → hands-on project experience → a second provider’s associate cert.
Certifications get you past the filter. Infrastructure you’ve actually broken gets you the job.
Everything above is worth your time, and the free tiers go further than most people expect. But the pattern is consistent across every cloud hiring loop: candidates arrive with three certs and freeze the moment they’re asked to debug a VPC routing issue or explain why their Terraform state drifted. Labs in a sandbox don’t produce that experience — real environments and real feedback do. If you want AWS and GCP taught through production-shaped projects, Liora’s Cloud & Data Engineering Bootcamp is the structured, cohort-based path.
- Real cloud environments — not sandboxes: you provision, you break it, you fix it, with the bill visible.
- AWS + GCP together — end-to-end data pipelines and infrastructure, the multi-cloud combination the market pays a premium for.
- Live sessions + career support — accountability that turns “course complete” into “job-ready.”
