<h1>What Is ZStack</h1>
<p>
ZStack is open source IaaS(infrastructure as a service) software aiming to automate datacenters,
managing resources of compute, storage, and networking all by APIs. Users can setup ZStack
environments in a download-and-run manner, spending 5 minutes building a POC environment all on a single Linux machine,
or 30 minutes building a multi-node production environment that can scale to hundreds of thousands of physical servers.

<p>A single management node is capable of managing <b>hundreds of thousands</b> of physical servers, managing <b>millions</b> of virtual machines,

The default networking model is built on <b>NFV(network functions virtualization)</b>, which provides every tenant a

self-managed, administrators need neither to purchase special hardware nor to deploy networking servers in front of
computing servers.
