Amazon S3 : Under the Hood

Most S3 courses teach you how to use it. This one teaches you how it works. S3 Under the Hood goes beneath the API and into the engineering: how your bytes survive hardware failure, how a flat namespace scales to hundreds of billions of objects, how a single PUT travels from your machine to durable storage across multiple physical buildings. No AWS console, no CLI, just the internals explained from first principles with interactive simulations at every step.

I'm a Cloud & Software Engineer. I've spent the last 5 years working on AWS, GCP and Kubernetes, and I'm certified in AWS Solutions Architect Pro, AWS Security, AWS AI Practitioner, GCP Cloud Engineer, CKA, Terraform and FinOps.

I started School of Cloud to teach IT, sysadmin and cloud topics the way I'd want to learn them: visually, with interactive elements, and at a level I think this space deserves.

It runs on LearnHouse, the open-source LMS I built before this. That's what makes the interactive lessons possible.

Really glad you're here. Hope you learn something cool. 💙
