 ### Multiple domains in an application
 
-Many customers who have workflows designed around internal web applications, especially those that were built internally, often see challenges related to interdependencies on multiple internal services. Separately, there can be challenges related to SPAs (Single-Page Applications) that make onboarding to a Zero Trust Web Access service difficult. For example, an application may have iFrames or other embedded systems that rely on different internal and/or external addresses.

-If your internal service operates in this way, we recommend specifying multiple top-level domains in a single Access application. Otherwise, if the goal of using multiple domains is to streamline or simplify policy creation, we recommend making one primary domain per application, and automating the rest of your deployment [using Terraform](/learning-paths/zero-trust-web-access/terraform/) or another Infrastructure as Code (IaC) service.
