You'll learn what the cloud actually provides, how its building blocks fit together, and what drives the bill. By the end you'll choose a sensible approach for a simple application and explain your reasoning to non-technical colleagues in plain language.
You'll learn what cloud computing actually provides, why organizations adopt it, and how cloud services are packaged, deployed, and divided between you and your provider. By the end you'll explain public, private, and hybrid models, tell Infrastructure, Platform, and Software as a Service apart, and describe how the largest providers organize their global infrastructure.
You'll learn the building blocks every cloud application runs on: virtual machines, containers, cloud functions, storage types, and networking. By the end you'll explain how each option works in plain language and choose a sensible building block for a simple application.
You'll learn how data is stored, queried, analyzed, and protected in the cloud. By the end you'll tell relational and NoSQL databases apart, explain why reporting is separated from live applications, and describe backup and recovery choices using recovery time and recovery point objectives.
You'll learn how Amazon Web Services, Microsoft Azure, and Google Cloud compare, how the same service appears under different names, and how cloud pricing actually works. By the end you'll explain a cloud bill, identify what drives it up, and compare total cost of ownership against running your own hardware.
You'll learn how cloud systems talk to each other through application programming interfaces and events, and how applications are structured as monoliths or microservices. By the end you'll design and defend a complete high-level cloud approach for a simple application.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
