They are slowly replacing the mainframe contracts by (private) cloud contracts
I see where they’re going, if they’re trying to learn from what went wrong with SoftLayer. IBM culture destroyed SoftLayer, so if they want another go at cloud, they do need that business to stay VERY fare away from the traditional IBM and their consulting business.
This is not unexpected. Startups will optimize for a few use cases and deliver, get acquired on those strengths only for the acquiring company to realize that ... the tech isn’t easily scalable.
I would love to see them build out a real cloud solution, perhaps even using datacenters full of their z15's. I can't imagine anyone competing with that on commodity hardware in terms of deployment speed and connectivity speed between instances in the same location. It would be crazy expensive though and I doubt they would ever consider it and someone at IBM would have to write a web interface / API into the system that mimics the options of all the current cloud providers.
That's a perfect opportunity to clone something and sell
