I’d be pretty happy if our legacy Mainframe systems got shut down, with a decent plan for how our suppliers would move forward to other technologies. As it stands there are only two national companies left who can handle mainframes in my country, so there isn’t much of a bidding war when we put systems into procurement processes, and it makes things really expensive over time.
I hope most enterprises entered the cloud with a mindset not to get locked in. I know we did, and in that setup, Microsoft can move forward as they see fit as long as they give us time to move on.
Not that I think any enterprise organisations were really using Azure Blockchain, I still haven’t seen a single reason to use Blockchain. Even if you live in a corrupt country, where decentralised trust might make sense, you still need an authority to back it up. This is why Bitcoin works for crime, they enforce it.
