To maximize operational efficiency, Zscaler built a highly scalable, global multi-cloud infrastructure. An organization is provisioned on one cloud and its traffic is processed by that cloud only.
Some configurations of the Zscaler service will require you to know the name of the cloud on which your organization is provisioned. For example, it is needed when you configure ADFS for admin SAML single sign-on for the Zscaler service.
You can find the name of the cloud in the URL that admins use to log into the Zscaler service. For example, if an organization logs into admin.zscalerbeta.net, then that organization's cloud name is zscalerbeta.net. See image below.
