Can a data center operating system yield higher utilization rates?
We've reached the point where management of the cluster has to go to a type of software that's more than a server operating system appointed as the master. Mesosphere's DCOS claims intelligence in knowing how to schedule tasks so that workloads are paired up that pose the minimum risk of conflicts. One is memory intensive but doesn't use I/Os after an initial data upload; another is I/O intensive. "You can get up to 90% utilization" out of cluster resources, said Trifiro, through the use of such knowledge. That may or may not be true now, but it certainly hasn't been true of cluster operations in the past.
