This is one of my favorite things about Thanos. We run Prometheus in multiple private datacenters, multiple AWS regions across multiple AWS accounts, and multiple Azure regions across multiple subscriptions. We have three global labels: cloud, region, and environment. With Thanos's Store/Querier architecture we have a single Datasource in Grafana where we can quickly query any metric from any environment across the breadth of our infrastructure.

It's really a shame that Loki in particular doesn't share this kind of architecture. Seems like Mimir, frustratingly, will share this deficiency.
