Deployment & single-tenant

Glotto runs as a managed SaaS by default. For enterprises with data-residency or isolation requirements, Glotto also offers a single-tenant cell: a dedicated instance in a customer-specified region/VNet, running the same control-plane code as the SaaS — behind the same proprietary cloud (there is no free self-host distribution).

How a cell is provisioned

A cell is described by a CellSpec (region, VPC, cell name) and stamped out by a parameterized Terraform module (templates/single-tenant-cell/) driven through a CellProvisioner abstraction (@glotto/core-provision). The concrete IaC backend (Terraform/AWS) stays behind the interface — it’s hermetically fake-tested in CI, while a live terraform apply is a documented, human-run step (never a CI dependency).

The result: ingest a customer spec into the dedicated cell and deliver SDKs, just like the shared tier — with the cell isolated to the customer’s account/region.
