Summary
In this chapter, we learned about how Prometheus can integrate with a variety of remote storage systems through the remote read and remote write protocols. We made that practical by deploying two popular remote storage backends: VictoriaMetrics and Mimir. Both can be used to extend Prometheus far beyond what simple federation is capable of in order to support advanced use cases involving the multi-tenancy and long-term storage of Prometheus metrics.
In our next chapter, we’re going to look at another popular open source project that integrates with Prometheus: Thanos. It integrates with remote storage protocols but also can be used for a whole lot more.
