‣ Low memory footprint
Why should people care about this?What’s in it for me?
OS, EC2, Admin APIsREST Based (xml/json)
Hardware Virtualization - osdoesn’t know its virutalizedParavirtualized – os knows its virtualized (has info about host)Container – operating system virtualization, shares the real hardware, jails off a user to the environment like chroot
