Kubernetes does not provide a rich multi-tenant experience out-of-the-box outside of Namespaces. Third-party tools try to bridge the gap generically, but there is no targeted solution to deal with telemetry data (logs, metrics, and traces). Sandor - the founder of Logging Operator that helps deal with logging on Kubernetes - gathered the team once again to re-evaluate the solution. The three main objectives were: to introduce tenants as first-class citizens, use OpenTelemetry Collector, and make it as simple as possible. The result is a new open-source project called Telemetry Controller. In this talk, Sandor will guide you through challenges like noisy neighbors, invalid configurations, parsing errors of multi-tenant logging, and how to solve them.
