SmartMachine 生存指南

by fcicq, CC-BY

SmartMachine 是 Joyent 家的虚拟化方案.
SmartOS 主要的卖点是 ZFS + DTrace + Zones (SmartMachine) + KVM (运行 Linux, Windows 等).
实际上 SmartOS 是 Joyent 以 Solaris 为基础 (因为 OpenSolaris 项目被中止而改名 illumos) 打包的操作系统.

SmartOS 作为 HOST 时, 虽然支持 KVM 虚拟化, 但不支持突发的 vCPU.
而 SmartMachine 是基于 Zones 的 (存储则是 ZFS), 比较类似 Linux 平台下 OpenVZ 或者 LXC 的方案.
资源用量由调度器决定, 只需要修改配额 (ZFS 也支持在线扩展) 就可以伸缩, 所以伸缩不需要重启.

<rationalrevolt> With ring, can some one help me understand why passing a var
                 to run-jetty allows me to reload code and have it reflect
                 immediately? (run-jetty #'handler {:port 8080 :join? false})
                                                                        [12:58]
<nDuff> rationalrevolt: passing the var object means it's involved in the
        lookup, and can be substituted/replaced.                        [12:59]
