What deployment model allows for all data and metadata to remain on customer-hosted infrastructure?

The chosen answer highlights the deployment model known as the "customer-hosted control and runtime plane." This model is significant because it ensures that all data and metadata are retained within the organization's own infrastructure. By opting for this deployment model, organizations maintain full control over their data, which is crucial for compliance with data protection regulations and internal security policies.

In this model, the control plane, which manages the environment, and the runtime plane, where applications are executed, are both hosted on the customer’s infrastructure. This prevents sensitive data from leaving the organization's network and can help in optimizing performance based on the organization's specific requirements.

This approach is particularly beneficial for businesses that have stringent data governance and compliance needs, as it allows them to safeguard their data while still leveraging the MuleSoft platform's capabilities. The flexibility it offers enables organizations to align their IT strategies with their own policies and existing systems seamlessly.

Other models, while useful in their respective contexts, do not provide the same level of control over data and metadata that a customer-hosted control and runtime plane does.
