Warewulf, bringing it into the present, and looking out into the future.
Warewulf v4 combines ultra scalability, flexibility, and simplicity with being light weight, non-intrusive, and a
great tool for scientists and seasoned system administrators alike. Warewulf empowers you to scalably and easily manage
thousands of compute resources.
### Architecture
One of the design tenants of Warewulf is how to scalably administrate many thousands of compute nodes. Generally
speaking, operating system state introduce a surface for potential discrepancies and version creep between nodes and
thus Warewulf has always gone with the "single system image" approach to clustered operating system management.
This means that you can have a single management node "image". For the last 20 years, we've been calling this a
Virtual Node File System (VNFS), but in hindsight, this is a container.
At its core, Warewulf v4 focuses on what has made Warewulf so widely loved: simplicity, ultra scalable, lightweight,
and an easy to manage solution built for both scientists and seasons system administrators to be able to design a
highly functional yet easy to maintain cluster no matter how big or small or customized it needs to be.
