"
Infrastructure Software is Dead"
Now Id love to tell you that its all because Mirantis OpenStack software is so much better than everybody elses OpenStack software,
but Id be lying. Everybodys
OpenStack software is equally bad. Its also as bad as all the other infrastructure software out there software-defined networking, software-defined storage, cloud management platforms, platforms-as-service, container orchestrators, you name it.
Its all full of bugs, hard to upgrade and a nightmare to operate. Its all bad.
