Multi-tenant software-as-a-service (SaaS) applications can contain many services maintained by different teams based on various technologies. A tenant is the most fundamental construct of a SaaS environment. CyberArk's customers that sign up to use CyberArk's SaaS applications represent tenants in the system.
A Tenant management service manages the tenant's provisioning and life cycle. Tenant management is usually one of the first services SaaS providers build for their SaaS control plane, as the tenant onboarding experience must be simple and fast.

In this talk, you will learn how CyberArk built a simple, cost-effective, scalable tenant management service.
The tenant management service's primary responsibility is adding new tenants and provisioning multiple CyberArk products to the tenants according to the customer's subscription.
In addition, the service manages the life cycle of the tenant and its products, from licenses and configurations to customer notifications (e.g., welcome email) and tenant deletion.
