Scenario: You have an application that uses Consul service discovery to connect to backend services in order to process data submitted by end-users. The front-end web service consists of 3 containers, while the backend service consists of 5 static virtual machines. All of the front-end web servers and the backend servers are registered with Consul. During normal operations, a user complains that the data processing is taking too long. To troubleshoot, you run a DNS query against the DNS name for the backend service, but discover that the response only contains three of the virtual machines. Why would Consul only respond with three servers rather than all five?
