A SaaS engineer says: "We need to spin up a new tenant for Acme Corp." What does 'spinning up a new tenant' typically involve?
'Spinning up a new tenant' is the act of running the tenant provisioning automation — creating all the infrastructure and data resources a new customer needs to use the platform. In a well-designed SaaS system this is fully automated: a new tenant can be live within seconds of sign-up, with isolated data storage, configuration, and access credentials.

What is the 'tenant onboarding pipeline' in a SaaS architecture?
The tenant onboarding pipeline is the technical workflow triggered when a new customer is created. It orchestrates everything needed: allocating resources (schema, buckets, queues), seeding default configuration, creating the admin user record, and sending the activation email. It is distinct from the UI-level 'onboarding experience' the user sees.

What does 'tenant configuration' refer to in a multi-tenant SaaS context?
Tenant configuration is the layer of per-tenant data that makes a shared application behave differently for each customer. Examples: custom subdomain, enabled/disabled features, storage quotas, SSO integration settings, locale preferences, and plan tier. It is typically stored in a 'tenant_config' or 'tenant_settings' table and loaded at request time.

A product manager describes the 'tenant lifecycle' as trial → paid → churned. What does 'churned' mean in this context?
'Churned' means the tenant left the platform — they cancelled. In the tenant lifecycle (trial → paid → churned), churn is the terminal state. It triggers an offboarding pipeline: deactivating the account, exporting data for the tenant if requested, and eventually deallocating resources. Churn rate is a critical SaaS business metric.

What is a 'tenant provisioning' failure and how is it typically handled?
Tenant provisioning failures are serious because they leave a new customer unable to use the product. The key engineering pattern is idempotency: the provisioning pipeline should be safe to re-run, detecting already-created resources and skipping them rather than duplicating. Saga-pattern compensating transactions are used in distributed systems to roll back partial provisioning cleanly.
