How does an IoT device in production get instructions from a server?

Question

My original ideas is to just ping an API every second or so. But if I have 10,000 of these out there - will I just end up DDOSing myself?

MQTT. Have the broker retain messages that are waiting for you when a connect or reconnect takes place.
