Basically, what Zun currently provides is<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>>"serverless" containers, which means Zun is not using VMs to isolate<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>>containers (for people who wanted strong isolation as VMs, they can choose<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>>secure container runtime such as Clear Container).
