I remember a couple of attempts to make the JVM run on bare metal (JavaOS was one if I recall correctly) and I think that, to a lesser extent, ChromeOS, FirefoxOS and company are trying to eliminate some of the bloat that&apos;s occurred.&lt;p&gt;The other day I spun up a CentOS6 server on a VM and it required a minimum of 512MB of RAM.  I remember building RedHat5 system (not RHEL5) with 32MB or 64MB.  What is the new server doing differently?  Functionally I have the exact same machines (yes, the newer machine is more secure, but should that really require 8x the memory?).&lt;p&gt;So these micro-systems allow the user to go &quot;back to DOS&quot; if they think Windows is too overblown.  And if you don&apos;t need a windowing system, and you have the language tools you need, why not treat the VMs (or hardware devices) as embedded systems.</text><parent_chain></parent_chain></comment><story><title>Truly elastic clouds with Zerg: OS-less Erlang on Xen</title><url>http://zerg.erlangonxen.org/</url></story>
