The scalability of the system is impressive, as the rack allows for the addition of up to sixteen Kubernetes, showcasing a highly scalable architecture. We have around fifty thousand users. I would rate it ten out of ten.

We have not experienced any scalability issues yet.

I have not scaled to test. 

While it scales, the base configuration is two nodes and it can go up to 25, I believe, so it can scale as you need to. As your business grows, as your compute requirements grow, you just add nodes as needed.

It doesn't really scale well at cloud size.
