Why Apple simply doesn't provide a cloud service?

With AAPL growing now at what I consider to be a "GDP premium rate" ~ 5% and with the iphone growth slowing down, what is left now for Apple is to capitalize on its services. This is now under attack in the EU. I am not a financial specialist but as a European I do however foresee a hard time for Apple to grow services revenue in the EU. Now that Apple has to offer search choices, that revenue with Google might also see some decline.

GenAI? They reshuffled the entire team working on Titan to focus on GenAI. How is that possible? are the skills really transferable? Vision Problem != LLM but again not an expert.

This led me to wonder, why isn't Apple competing in the cloud business? I don't mean like AWS or Azure but for its developers? When a developer onboard on IOS, they make use of the store and the SDK but all cloud services the app uses is running somewhere else. Wouldn't Apple be able to justify 30%+ cut of the developer's revenue if part of the deal was access to Apple cloud infrastructure to run the App services? $Apple(AAPL.US)$
