    • Scenario: You have multiple services registered with Consul for your e-commerce site, including the front-end service, the shipping service, the inventory service, and the
      cart service. To safeguard your customer's shipping addresses, you want to ensure that communication between the front-end and the shipping service is denied and that
      traffic is only permitted from the cart service.
