Serverless computation is another stage in the evolution of computational unit management. With a serverless architecture, a function call to the cloud spins up a transient container, calls the function on that container, and then spins down the container. Ryan
http://traffic.libsyn.com/sedaily/Serverless_Edited.mp3Podcast: Play in new window | Download Virtual machines were the unit of cloud computation for many years. Amazon Web Services pioneered the democratized model of allowing anyone to deploy a service to the cloud, running on a virtual machine on Amazon’s servers. After virtual machines, containers have become the unit of scale in the cloud. We break up our virtualized servers into even smaller units of computation called containers.
From Eric Tschetter’s answer via Quora: The difference you are asking about though is ParAccel vs. Druid. ParAccel is the software that Amazon is licensing for RedShift. Aside from just potential differences in performance, there are some functional differences (these are all based on a cursory understanding of what ParAccel does, I’ve read what I could find on it, but a lot of my understanding is extracted from interpretations of marketing
