Mirantis is well known as a pure play OpenStack vendor. The company is (was) entirely focused on offering organizations help leveraging the OpenStack open-source cloud computing platform.
As we’ve seen over recent years, the OpenStack initiative, while popular in some areas (science and telco, for example) hasn’t seen the sort of service provider revenues that justify the massive valuations of venture-backed companies.
So, while other vendors have gone to the wall and had to sell themselves off to the highest bidder, Mirantis seems to be making a determined effort to pivot into adjacent areas. No longer is this a pure-play OpenStack company; Mirantis now pitches itself as an organization that “helps top enterprises build and manage private cloud infrastructure using OpenStack and related open-source technologies.”
