Mule applications that implement a number of REST APIs are deployed to their own subnet that is inaccessible from outside the organization. External business-partners need to access these APIs, which are only allowed to be invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet is accessible from the public internet, which allows these external partners to reach it. Anypoint Platform and Mule runtimes are already deployed in Partner-subnet.
