I like the model of one cluster per team and one app per namespace. It's also nice to have dev clusters separate from prod clusters. Then each "application" gets a namespace. It can be tricky to decide which containers fit into which application exactly. It turns more into logical organization at that point. If it's a startup / small company you can throw everything into one cluster and divide it up by namespace. Not ideal but not the end of the world.
