 This option is designed for users who are using ClickHouse Cloud. In this deployment pattern, both ClickHouse and HyperDX are hosted in ClickHouse Cloud, minimizing the number of components the user needs to self-host.
 
 As well as reducing infrastructure management, this deployment pattern ensures authentication is integrated with ClickHouse Cloud SSO/SAML. Unlike self-hosted deployments, there is also no need to provision a MongoDB instance to store application state — such as dashboards, saved searches, user settings, and alerts.
