Oh really do tell? What knowledge do you have to say this of each infrastructure? You don't know.
The thing with Microsoft is that they have large investments into, and a ton of experience with operating, high-availability infrastructure and systems. They run their own cloud computing platform (Azure), and handle dwarfing loads from client devices running Windows (store, updates, product activation etc.) on a daily basis. They are, and have in the past been, running large-scale operations with hundreds of millions of users (think Hotmail, MSN, Office 365). They have been doing these things for decades, because they are a software and services company. It's hardly a stretch to think that Xbox Live greatly benefits from Microsoft's legacy.
