| What | A scalable approach that involves provisioning multiple independent copies ("stamps") of a solution, each hosting a subset of tenants or workloads, enabling linear scale-out, regional deployment, and data separation. | Supports performance efficiency and reliability by isolating workloads, enabling near‑linear scale-out and reducing cross‑tenant impact. |
| Used with | Multitenant or SaaS workloads on IaaS/PaaS needing horizontal scale and tenant isolation; deployment rings for staggered updates. | Aids operational excellence and security through repeatable deployments and per‑tenant isolation; aligns with infrastructure‑as‑code and safe deployment practices. |
| When | When single deployments hit scale limits, incur non‑linear cost, or must separate customers by size, update cadence or region. | Improves reliability and compliance by deploying stamps in specific regions and accommodating diverse customer requirements. |
| Not Suitable For | Simple solutions that scale easily on one instance; systems needing global data replication, partial component scaling, or serving only static content. | Adds cost and complexity; not ideal when a single instance suffices or data must be shared across all deployments. |
| Related To | Geode pattern, sharding, traffic routing, gateway offloading; stamps implicitly shard data and may use routing services. | Sharding Pattern, Gateway Offloading Pattern, Gateway Routing Pattern, Geode Pattern |
