Well I definitely agree that decentralized transactions are going to completely disrupt today's business transaction processing - when, I cannot say, but it will definitely happen. History is replete with examples of how more efficient technology wins out over time - even when strong opposition is offered from those making money from legacy processes (e.g. Uber, RIAA, etc). However, I'm not sure how blockchain technology is going to disrupt hosting and cloud computing, unless you're just talking about the contracts that support these services?
