They have a lot more software in the works, such as Cassanda, MongoDB and Spark [1]. It&#x27;s a push to have good software support for the IBM LinuxONE machine [2], essentially an IBM z Systems (z13) mainframe that will only run Linux on KVM (i.e. without expensive z&#x2F;OS or z&#x2F;VM &#x27;legacy&#x27;).<p>I&#x27;m not sure about the costs, but it might make for a compelling platform as a &#x27;private cloud&#x27; solution. A single mainframe is a lot easier to maintain than racks full of x86 boxes. Apparently one LinuxONE Emperor machine can run up to 8,000 Linux VMs [3] (not sure with what load).<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;linux-on-ibm-z" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;linux-on-ibm-z</a><p>[2] <a href="http:&#x2F;&#x2F;www-03.ibm.com&#x2F;systems&#x2F;z&#x2F;os&#x2F;linux&#x2F;linux-one.html" rel="nofollow">http:&#x2F;&#x2F;www-03.ibm.com&#x2F;systems&#x2F;z&#x2F;os&#x2F;linux&#x2F;linux-one.html</a><p>[3] <a href="http:&#x2F;&#x2F;www.zdnet.com&#x2F;article&#x2F;linuxone-ibms-new-linux-mainframes&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.zdnet.com&#x2F;article&#x2F;linuxone-ibms-new-linux-mainfra...</a>
