IBM is mainly a consultancy business, so they basically back integrated with the cloud os - kubernetes, or more specifically in this case - open shift. The only issue here is that are around 23 or more certified kubernetes distors, so this might have been an…
If anything I am skeptical about Kubernetes' future. Not in the short term, k8s/docker are the MongoDB of the late 2010s and the same sorts of people are jumping on the bandwagon. But look at the discussion about the AMD EPYCs in Google Cloud. Big machines are now getting so big that a bog standard OS running a bunch of processes is going to provide more than enough power for even very large websites.
One machine now provides more power than a whole rack used to, and horizontal scaling technologies are expensive. A research paper from 2013 showed that just scaling up beat the performance of scaling up for virtually all jobs analysed, which came from Microsoft, Yahoo, and Facebook. So the sorts of companies that are poster-children for this kind of cloud technology.

There's not much career or intellectual capital to be gained by just running things on big boxes, but, eventually the cost effectiveness of this will become hard to ignore.
