And of course Vmware has already been integrated into EMC years ago, quite successfully. Although you could argue the ongoing Dell/EMC saga could jeopardize that... Depending on how well you think it’s going.
From what I've seen, they're doing a lot more sales than RedHat.
However Pivotal CloudFoundry is not their best-seller... I doubt it’s even in the top 5. Vmware’s empire is built on Vsphere/esx (their core business) and, more recently Vsan (storage) and NSX (networking). The former is the largest. The latter two are the fastest growing.
Container platforms are a relatively new category, so sales are not huge. In that category Cloudfoundry might be slightly ahead, but I think Openshift has more momentum because their early bet on Docker then Kubernetes is paying off. Pivotal has PKS but it feels half-hearted.
I'm under the impression that cloud foundry is specifically targeting mega corporation like fortune 100 banks. In that context, it only takes a few sales to capture the market and a lot of money.
I didn't see OpenShift used anywhere.
Disclosure: I work for Pivotal.
