Google is drawing from the work of the open-source community to offer its cloud customers a service to better manage their clusters of virtual servers. On Monday, the Google Cloud Platform started offering the commercial version of the open-source Mesos cluster management software, offered by Mesosphere. With the Mesosphere software, “You can create a truly multitenant cluster, and that drives up utilization and simplifies operations,” said Florian Leibert, co-founder and CEO of Mesosphere. Leibert was also the engineering lead at Twitter who introduced Mesos to the social media company.
