AWS Skill Builder

AWS Skill Builder offers over 600 free digital courses covering AWS services, machine learning, and infrastructure. The platform includes hands-on labs where you can practice on actual AWS resources, plus dedicated tracks for AWS certification exams like the Solutions Architect and Developer Associate paths.

This works best if you're entering cloud infrastructure or already working with AWS. It's particularly strong for certification prep compared to general MOOC platforms, and competitive with Microsoft Learn for cloud-specific depth.
