What does this mean?

This website is served by an Nginx web server running on a virtual machine powered by Unikraft Cloud.

The web server runs on the ultra-efficient, lightweight Unikraft operating system.
The entire software stack – the tailored Unikraft kernel plus Nginx – comes in at only 90MB (excluding the website’s content) and boots in around 10ms.

Unikraft Cloud offers advanced, next-generation scaling capabilities. This server uses scale-to-zero, which means the virtual machine is completely stopped (put into standby) when no requests are being handled. As soon as a new request arrives, the Unikraft Cloud Platform instantly starts it up again – with minmal delay, thanks to the efficiency of the Unikraft kernel.

Does the indicator show the real server state?

No, it is a CSS visualization, but it represents how the server behaves with the chosen scale-to-zero configuration: the VM is stopped after one second of inactivity (after having served the last request).

Can I also use Unikraft Cloud?

Yes! Simply sign up.

A free plan is available (this website uses it too). No credit card required.
