In which runtime are Mule Domains supported?

Mule Domains are supported in customer-hosted runtime planes because they provide a way to isolate applications on a single Mule runtime engine. This means that different applications can share the same runtime, but they can also maintain separate configurations, resources, and security settings through the use of domains. This capability is particularly beneficial for organizations that require a clearer separation of applications for security, compliance, or operational management reasons.

Customer-hosted runtime environments allow enterprises to have more control over their configurations and the resources they allocate, which includes the ability to implement and manage Mule Domains effectively. By leveraging these domains, organizations can manage their applications in a way that promotes reusability and resource sharing while still keeping the applications logically separate.

In contrast, other runtimes, such as those in the public cloud, may not offer the same level of customization and control as customer-hosted environments, making domains less applicable or useful in those contexts.
