Architecture

Sitefinity Cloud has a single-tenancy architecture, where the services for each customer are completely isolated via dedicated infrastructure contained in separate Azure subscription and Azure Active Directory.

After purchasing a Sitefinity Cloud subscription, each customer gets their own dedicated organization. Each Sitefinity Cloud subscription corresponds to a project in the organization. When a customer purchases additional Sitefinity Cloud subscriptions, these are added as extra projects.
The following diagram illustrates a high-level Sitefinity Cloud customer organization:
