Yes ,Google’s days are numbered, but I don’t think you can put Amazon in the same group. 
AWS regions are all over the world, redundant, self sufficient, own the network backbone, and extremely flexible, scalable, distributed and highly automated for its customers. Block chain is part of the future, and it can possibly be integrated in everything including the cloud, but cloud computing has not hit its peak. Cloud computing is not just about big data, it’s about freeing the customer from maintaining, paying and amortizing for hardware, power, networks and systems and even software, and focusing on their product. Amazon is pay as you go, and will probably adopt blockchain in its solutions. Amazon is doing it right......
