How does an instance handle multiple domains in domain separation?

When discussing how an instance handles multiple domains in the context of domain separation, the practice of isolating each domain is a fundamental aspect. Domain separation is a strategy used to ensure that different domains (which can represent different business units, departments, or even customers) can operate independently within a single instance of software.

Isolating each domain creates a controlled environment where data, configurations, and processes can be managed separately. This means that users in one domain do not have access to the data or processes of another domain, which enhances security and reduces the risk of data leakage. Each domain can have its own set of rules, workflows, and even user permissions tailored to the specific needs of that domain.

Implementing domain separation in this manner allows for greater flexibility, compliance with regulations, and improved governance of the information handled within the instance. This isolation ensures that changes or issues in one domain do not negatively impact other domains, fostering a more robust and secure overall system architecture.
