Frequently asked questions
Which cloud certification course has the highest ROI in 2026?
AWS Cloud Practitioner (CLF-C02) has the highest ROI for beginners — it is the most requested entry-level cloud cert by employers, takes 12 hours to prepare, and is free to audit on Coursera.

Start with AWS Cloud Practitioner if you are undecided — AWS holds ~31% of cloud market share and the cert is recognized globally. Choose Azure Fundamentals (AZ-900) if your employer uses Microsoft 365. Choose Google Cloud if you work with data or ML, where GCP has strong tooling.
