# Deployment Blueprints Turns architecture decisions into executable deployment tracks. ## Blueprint tracks - Single-region starter SaaS topology. - Multi-region production topology. - Shared services + per-tenant workload topology. - Deployment-stamp topology with a global control plane and tenant placement strategy. - Reference CI/CD promotion model. ## Multitenant deployment requirements Apply the deployment-stamp guidance from [Architect multitenant solutions on Azure](https://learn.microsoft.com/en-us/azure/architecture/guide/multitenant/overview): - Define stamp boundaries, capacity limits, tenant allocation, and scale-out triggers. - Separate global routing and tenant-placement metadata from stamp-local workload resources. - Support controlled tenant movement between stamps, including data migration and routing changes. - Use repeatable IaC and versioned configuration so stamps remain consistent while supporting safe upgrades. - Define blast radius, rollback, and regional evacuation behavior. ## Deliverables - Deployment sequence and dependency graph. - Environment-specific parameter model. - Stamp topology, tenant placement algorithm, and migration procedure when stamps are used. - Release and rollback strategy guidance.
