Is single system image still a thing?
Aren't systems like Apache Mesos (which didn't exist back nearly 10
years ago in 2007 when the author wrote that post) the natural successor
to DataSynapse FabricServer, and an example of the "distibuted operating
system" he's talking about? I.e., just a big pool of CPU cores, where
different portions of the pool can be utilized for different types of
distributed workloads.
Sounds more like what he's talking about. Are these kinds of systems
gaining much traction? I'd never heard of Mesos.
Yes, I think so. Many companies are starting to migrate their
Hadoop/Spark/etc. infrastructure on to it. (We're starting to do that
here at YP.)
It makes sense: if you're using Hadoop, Spark, and other distributed
systems, it doesn't take long to figure out it's more efficient to have
that a system that can run any of those on the same cluster simultaneously.
Mesos came out of the same Berkeley Lab that built Spark. More info on
its history here: https://en.wikipedia.org/wiki/Apache_Mesos
