Single-Tenant SaaS Provisioning System
An automated system that uses the Automation API to dynamically create and manage dedicated infrastructure for each new SaaS customer.
Overview
In a single-tenant SaaS architecture, each customer gets their own isolated set of infrastructure resources. A provisioning system built with the Pulumi Automation API automates this process. When a new customer signs up, a backend service is triggered. This service uses the Automation API to create a new, dedicated Pulumi stack for that customer, configure it with customer-specific details, and deploy a full copy of the application infrastructure. This enables SaaS providers to scale and manage thousands of unique customer instances programmatically.
✨ Key Features
- Automated provisioning of per-customer infrastructure stacks.
- Programmatic stack creation, configuration, and deployment.
- Scales to manage thousands of unique customer environments.
- Integrates with customer signup and management workflows.
- Enforces tenant isolation at the infrastructure level.
🎯 Key Differentiators
- Leverages a full-featured IaC engine for robust and repeatable deployments.
- Manages the entire lifecycle of tenant infrastructure, not just compute.
- Provides a consistent, programmatic approach that can be integrated directly into the SaaS control plane.
Unique Value: Enables SaaS businesses to scale single-tenant offerings efficiently and reliably by automating the entire infrastructure provisioning and management process.

✅ Best For
- Cockroach Labs uses the Pulumi Automation API to manage Kubernetes clusters on behalf of their CockroachDB-as-a-service customers, simplifying the management of their multi-instance SaaS architecture.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Multi-tenant SaaS applications where customers share infrastructure.
- SaaS products with a very small number of customers where manual provisioning is feasible.
🏆 Alternatives
Compared to manual processes, it's infinitely more scalable and less error-prone. Compared to custom scripting with cloud SDKs, it benefits from Pulumi's declarative engine, state management, and diffing capabilities, making updates and deletions much safer.
