Matomo AZURE hosting / Kubernetes

Hey folks.

Is there anyone who runs multiple Matomo Instances in AZURE?

At this time I run multiple on-prem Matomo hosts and want to chance to AZURE Kubernetes Infrastructures.
Im not sure an nginx infrastructure with one big DB instead of multiple smaller DBs is a really good idea.
ATM I store 70GB date a year an delete after 3 years.

Any experiences
