Sure. But ten years ago, people were using OpenVZ widely in hosting and so on. The benefits were very clear. Yet at that time period, Microsoft went in the opposite direction as they thought HDD space was growing without limit. (Vista introduced winsxs and other disk hungry features.)
They were ahead with App-V (Softricity, streamable apps which work offline in lieu of Citrix virtual desktop or Moka5 VMs), but the landscape on servers and VDI changed.
Did that make it possible to deploy, say, IIS and DNS in separate containers, easily? I always saw it sorta aimed at end-user apps. Also note it's yet another licensing hurdle.
