Don't underestimate Amazon. They have the world's largest (?) server-infrastructure and logistic infrastructure in place. Most of the other companies rely on Amazon.
Could imagine that Google's infrastructure is bigger. Their cloud service is clearly smaller than AWS but they have much more computing demand than Amazon has for their main business. So overall Google could be ahead of Amazon.
Logistics infrastructure of Amazon is not the largest either. In the US, Fedex and UPS will have more infrastructure. Not that many warehouses, but when it comes to distributing items they should be larger. Worldwide, DHL Group could be the largest. They have a substantial freight forwarding business so that they will move far more goods every day than Amazon does.
The important thing, though, is that no one has both of it in one company. We'll see how valuable that turns out to be (maybe not at all, maybe very).
