We’re extremely pleased with Talos. Much more secure than Azure (our cloud of choice, unfortunately) which run a full-blown Ubuntu underneath. We haven’t run into any issues with Talos and upgrading is super easy with the talosctl tool, both Kubernetes and Talos version.

We currently have a thanos instance in each cluster. We could move it to a separate cluster to reduce some overhead, but the current approach works. We’re ingesting about 60Gi per day of metrics into the S3 bucket, so we might have to optimise that.
