[FinOps] Intra Kubernetes cluster cost visibility

Challenge

Kubernetes is become the platform-centric brick inside most IT infrastructure.
And to avoid the proliferation of too many distributed Kubernetes clusters, some organizations started a multi-tenancy / shared strategy.
So, basically, less Kubernetes clusters to manage but more challenges on:

• resource isolation
• cost visibility

Focusing on the second point, I'd like to report a couple of really useful tools in order to start getting visibility of cost with a breakdown also to namespaces, both compatible with major cloud providers.
