1. A method comprising:
establishing a traffic flow associated with an application such that:
control-plane traffic of the traffic flow is sent to a control-plane node associated with the application; and
data-plane traffic of the traffic flow is sent to a data-plane node associated with the application;
receiving, from a client device, a first packet including a first hostname that is associated with the application;
based at least in part on the first packet including the first hostname, sending the first packet to the control-plane node associated with the application;
receiving, from the client device, a second packet including a second hostname that corresponds with the data-plane node associated with the application, the second hostname provided to the client device by the control-plane node; and
based at least in part on the second packet including the second hostname, sending the second packet to the data-plane node associated with the application.
