What is multicluster GitOps?

As we adopt containers and Kubernetes, we end up running and maintaining multiple Kubernetes clusters. Some are used as production, some as QA while others are used as short-lived dev environments. There are many cases where we want to package and deploy applications to these clusters. The kind of applications we want to deploy may also vary a lot. On one hand, we have third-party off-the-shelf applications like Prometheus, Grafana, Elasticsearch, Kafka, etc. which have their own Helm charts. In many cases, these applications only need to be configured to our use case, pinned to a specific version and they can be deployed. While on the other hand, we have bespoke applications that are updated & deployed multiple times a week. Even multiple times a day in some cases.
