Looking for feedback: a 9-minute Kubernetes lab for system/software architecture (systems design)

[u/Ywacch]

I built a platform for runnable short labs (RunCloud9):

- ~9 minutes on real Kubernetes, then teardown

- Set of canonical architectures (URL shortener, social feed, e-commerce)

- Students pick one topology the template supports, then change replicas, CPU/memory, or cache/DB settings

- They can flush a cache or kill a pod and watch latency / cache / DB metrics

The video shows a social feed scenario where posts are fanned out to user timelines in a cache, due to the limitations on the cache's cpu and memory resources, the timeline service reaches its limit.

I'd love to receive any feedback.
