One big cluster vs. many small clusters (blog post idea)

[weibeld]

Should you have one big cluster or many small clusters for your applications?

If you have 10 applications, should you run each of them on its own small cluster, or run all of them on one big cluster?

Related to "Should you have many small nodes ore few big nodes in your cluster?" blog post.

Here the level of granularity (to split across the small or big clusters) are applications, not pods like in the related article.
