There are multiple hosting options for Pixie.
Pixie is a hybrid system, with a cloud component (Pixie Cloud) and an in-cluster component for data persistence and storage (Vizier). See Architecture for more details.
While Vizier will always be deployed directly onto your Kubernetes cluster, there are multiple options for Pixie Cloud.
Follow the Community Cloud for Pixie Guide if you want to deploy Pixie without needing to host your own version of Pixie Cloud. Community Cloud for Pixie provides community hosting of the cloud component to simplify your Pixie deployment.
With Community Cloud for Pixie, telemetry data is exclusively stored on your Kubernetes cluster (not in Pixie Cloud).
Pixie also supports for self-hosting of the entire platform, including Pixie Cloud. Follow the Self-Hosted Pixie Guide for the steps.
