What does "They are selling it in a big way" mean?
I've never heard of it, and neither have any of the software engineers who are next to me at the office.
RedHat OpenShift also bombed. They had a great start 11 years ago, but then didn't innovate, and worse, released a 2.0 that wasn't backward compatible. They used the 2.0 release as an excuse to kick off all free plans. What a joke. There's a reason Red Hat isn't a leader in Cloud.
OpenShift is fantastic and I wouldn't hesitate to recommend it to any medium sized startup and up. I run it in my closet. Most medium sized startups end up building out an OpenShift-like K8s but they use 6 months to a year plus to do it.
Upgrades within major versions are totally painless, one-click affairs.
PCF is still making bank but the industry has rallied around K8s. So growth has stalled but it has a happy customer base.
Unfortunately there’s no real equivalent (OpenShift is not really “it”) on K8s unless you’re assembling several products together with a lot of glue. Which is what everyone does, with varying quality.
