How we live-migrated massive Cortex clusters to blocks storage with zero impact to Grafana Cloud customers
January 20, 15:01 UTC. I was sitting in my home office, watching the screen and feeling a mix of emotion and nostalgia as a pod was getting terminated. We have thousands of pods, continuously starting and terminating, and I’m definitely not spending my days watching them, so why was this one special? The terminating ingester-0 pod was the very last Cortex ingester running on chunks storage in Grafana Labs’ infrastructure.
