 Your cluster's telemetry data flows through Pixie's Cloud via a reverse proxy as encrypted traffic without any persistence. This allows users to access data without being in the same VPC/network as the cluster. Pixie offers [end-to-end encryption](/about-pixie/faq/#data-collection-how-does-pixie-secure-its-data) for telemetry data in flight.

Pixie uses the Kubernetes [Operator pattern](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/) to manage its Vizier, which handles data collection and query execution (see the [Architecture](/about-pixie/what-is-pixie/#architecture) diagram).
